Test machining on a mill/turn centre usingtwo spindles, two turrets and Y-axis, has shown that times can be cut by over 40% and the work of four machines carried out by one machine.

Two spindles, two turrets, Y-axis control, and up to eight axes in one complete multi-axis turning package - it has to be the Mori Seiki ZT, which can be seen on stand 5340 at MACH 2006. Combining operations provides significant savings during manufacture. Components which previously required several turning and milling operations on separate machines can frequently be done in one operation on the ZT.

Not only does this reduce machining and handling times, but it also improves quality by eliminating resetting operations and their associated errors, as well as, making far better use of available space on the shop floor.

Test machining by Mori Seiki has shown that machining times can be cut by over 40% and the work of four machines carried out by one machine and one operator.

The ZT machines offer increased capacity.

The ZT1500YB has 1000mm between spindle large noses, a maximum turning diameter of 190mm, bar work capacity of 65mm and Y-axis travel of 100mm, the largest in its class.

Using the technology available on the machine, multiple operations can be carried out simultaneously, integrating processes and balancing machining times to achieve the optimum cycle time.

The ZT's dual turrets include a quick change type turret for VDI tools, dramatically reducing tool change times.

Fast setting further adds to the flexibility of the machine.

Smaller batch sizes are viable, helping users to offer shorter delivery times to their customers, and at the same time reduce inventory levels.

Castings for the ZT have been designed to maximise the stiffness of the machine structure using high quality Japanese manufactured castings, with carefully designed ribbing for optimum chip removal.

Combined with the high output oil cooled spindle, which is 18.5kW on the ZT1500, the machine can achieve metal removal rates of 162.7mlitre/minute at 6mm depth of cut and precision finishes of 1.07 micron Ry.

A leading supplier of tungsten carbide tooling has invested in a bar-fed mill/turn centre to machine difficult-to-cut tooling materials.

Stellram, a leading supplier of tungsten carbide tooling with manufacturing locations in Europe and North America, has invested in a Matsuura supplied Stama Mill Turn centre Stellram has developed a reputation for providing the best cutting tool solutions for difficult to machine materials - stainless steel, super-alloys, and titanium. The company focuses on these materials, while still servicing general tooling needs for less demanding materials. Stellram has chosen a very high specification Stama MC726MT-G Mill Turn machining centre from the Stama Mill Turn range, configured with a sub-spindle for six-face machining.

Tooling will be produced with this new mill turn, including Stellram's latest product introductions such as high velocity cutters for airframe components, patented anti-rotation tooling for heavy feed milling, plunge milling tools and high feed facing cutters.

Supplied with a proven and integrated bar-feed system, gripper conveyor, 150 tool extended ATC carousel, a 12K HSK63 main spindle with 70bar through spindle coolant and extended deep hole drilling capability, the Stama MC-726MT is part of the ongoing capital investment strategy through out the ATI Corporation.

Stellram's parent company, Allegheny Technologies, (NYSE: ATI), is one of the largest and most diversified specialty material producers in the world.

Speaking of the investment, Hugh Welch, Stellram's UK manufacturing manager said: 'It is a true reflection of our long term objective to invest in the highest specification equipment in order to produce the latest tooling technology.

Two fixed head CNC turning centres - to be shown at the UK's MACH 2006 exhibition - have already been sold, informs a UK supplier, which said the machines will bedelivered after the show.

Two fixed head CNC turning centres - to be shown at the UK's MACH 2006 exhibition - have already been sold, informs a UK supplier, which said the machines will bedelivered after the show. MACH 2006 is already guaranteed to be a success for Macro CNC. Two of the Miyano fixed head turning centres that will appear on stand 5538 have already been sold.

To be delivered to customers immediately after the exhibition, the largest machine, a Miyano ABX-51TH2 two spindle, 51mm capacity three-turret turning centre with two Y-axes is capable of processing high-end parts efficiently in a single set-up.

This machine will be delivered to Mann Engineering of County Wexford, Ireland.

The second machine, a Miyano BNJ-42SY will be delivered to HS Rowe and Partners.

The 42mm capacity two spindle, two turret compact turning centre with Y-axis will be delivered to the company's Kingswinford facility in the Midlands.

The orders for both machines highlight the market trend that sees subcontract manufacturers requiring rigid fixed head turning centres with exceptional capability and a capacity to manufacture larger workpieces.

Mann Engineering, a subcontractor, designer and manufacturer of bar feed systems and bespoke systems for special manufacturing applications has purchased its second Miyano ABX-51TH2 to improve its productivity and manufacturing capabilities.

The current Miyano ABX-51TH2 at Mann Engineering has enabled the company to complete components in one-hit.

The third turret on the machine has provided the company a productivity improvement of 20%.

With such impressive results, the company was intent upon buying yet another Miyano from its Irish agent Premier Machine Tools.

Whilst HS Rowe, a subcontract precision turned components manufacturer will acquire its Miyano BNJ-42SY machine to compliment its current range of fixed head turning centres.

Following the purchase of a Miyano BNJ-42S in 2005, Steven Tyler of HS Rowe commented: 'The BNJ-42S has been a tremendous machine and as part of our philosophy of 'value adding contributions per employee head', the introduction of Miyano machine tools to increase productivity has been instrumental.' At MACH 2006, HS Rowe will also be discussing with Macro CNC the possibilities of introducing automated machines from the LZ series.

A 5-axis mill-turn centre for one-hit machining of components up to 710mm in diameter by over 1.5m long features advanced collision avoidance - the CNC monitors the machining area in real time.

Okuma has launched a new mill-turn centre for one-hit machining of components up to 710mm in diameter by over 1.5m long. Called Multus B400, the 5-axis machine features advanced collision avoidance whereby the Okuma OSP-P200 control monitors the entire machining area in real time during an automatic machining cycle or, unusually, in manual mode as well, preventing the axes from being wound by hand into a collision situation. Availability in the UK is through sole agent, NCMT.

Whereas the focus of competitive simulation and interference-checking software is on the tool, holder, spindle and fixture, in addition to the component, Okuma takes a wider view, mapping also the spindle head, slideways and guarding.

The result is a reduction of up to 40% in the time needed to write programs involving the simultaneous interpolation of multiple axes.

In place of a turning tool, the swivelling B-axis spindle accepts HSK-A63 (CAPTO C6) tools, exchanged from a 20-station (optionally 40- or 80-station) magazine, for carrying out heavy prismatic machining operations using 10kW (optionally 14kW) of power.

The milling spindle swivels from -30 to +195 deg in 0.001 deg increments.

Both the tool and the motion of the turret are powered by one Prex reluctance motor (Okuma patent), whose absence of windings on the rotor minimises heat generation and promotes accuracy.

Roller bearing linear guideways allow weight-bearing capacity and precision to be combined with 40m/min rapid traverse in X and Z, 26m/min in the +/-115 mm Y-axis, leading to short idle times.

As befits a machine required to turn large components, the C-axis spindle is powered by either a 30/22kW or 22/15kW motor, switchable in two ranges, the former figures representing 30 min ratings.

The 14.5-tonne, slant-bed machine is capable of high accuracy in a normal shop floor environment, as tests have shown thermal deviation to be less than 10 microns over a 24h period despite a variation in ambient temperature of 8 deg C.

This performance is a result of the application of Okuma's patented Thermo Friendly Concept to both the machine structure and the spindle, together with the use of 0.1 micron resolution linear scales in the orthogonal axes.

Big, complex machines can often be cumbersome to use, but not so with the Multus B400.

Spindle centreline is only 1.2m from the floor and 550mm in from the guarding, there is a lightweight door for ease of use, and a coolant tank that detaches from the front, rather than having to slide it out lengthways.

There is also a convenient, swivelling operator's panel for the Okuma OSP-P200 control, which uses an industrially hardened PC to run both the Okuma operating system and Windows XP.

It is therefore possible to display Excel files listing machining instructions, tooling, offsets and performance results.

Two USB 2.0 ports are provided for program download, data capture and even the attachment of a bar code reader.

Starting from a twin-spindle, twin-turret multi-axis lathe, an electric actuator company engineered a manufacturing system complete with tooling and programs for six components.

When Rotherham, UK-based Precision Magnetics launched an innovative electric actuator for the aerospace industry it took a bold decision. Even though it had no history of advanced machining it realised that it had to make these complex and sophisticated products in-house. Turning Technologies, the UK distributor for Nakamura-Tome and a member of the Engineering Technologies Group, provided the turnkey solution and support that made this possible.

Historically, Precision Magnetics had specialised in the manufacture of extremely powerful Neodymium Iron Boron (rare earth) magnets.

The materials had originally been developed for small powerful electric motors to be used in automotive components such as pumps and windscreen wipers and were also widely used in computer disk drives.

Until a couple of years ago, this was a significant part of the company's business, but the production route was becoming unsustainable in a global market.

The Neodymium ore from China was shipped to the US for refining into sintered bar that was sent to the UK for processing into magnets that were then sent to the disk drive manufacturers in Singapore.

The solution, a manufacturing joint venture in China, meant that Precision Magnetics had to look at new applications for the magnets.

Andrew Myers, managing director of Precision Magnetics, said that this move came as no surprise and the company was already looking to develop value-added applications that incorporated the magnets into more complex components, particularly for the aerospace sector.

Because these rare earth magnets are so powerful they can be used to make electric motors that, weight for weight, are much more powerful than hydraulic actuators.

This makes them particularly attractive for driving control surfaces such as ailerons, rudders and elevators.

But having sold the concept to its Tier One customers, Precision Magnetics then had to look at how it would be able to manufacture the actuators.

'We made the first ones ourselves by buying in the machined parts from a subcontractor,' said Myers.

'But when you sign long-term contracts, you get the benefit of long-term business, but you have to be able to offer year-on-year 'cost-downs.

To be able to maintain the business we had to take some of the cost out - and the biggest cost element was the bought-in components.

The only solution was to make the parts ourselves.' But these were complicated parts in difficult materials and there was no history of CNC machining within the company.

'We did not have any in-house skills so we had to find a partner who could offer us a complete solution,' said Myers.

'After researching the market and looking at a number of possible routes we decided that we wanted to work with Turning Technologies.' Turning Technologies was able to help because it had the right technology to produce the parts in one setting - which the required levels of accuracy demanded, but, perhaps more importantly, Precision Magnetics needed to be able to put its faith in a company that could take them on from basic toolroom machines to the latest multi-axis, 'one-hit' machining techniques.

Starting from a Nakamura-Tome WT-300 twin-spindle, twin-turret multi-axis lathe, it engineered a production-ready manufacturing system complete with tooling and programs for six components.

'They provided the best technical solution and it was based around a single machine.

That was important for us too.

For this application and with our lack of experience we were much happier having just one machine to concentrate on,' said Myers.

The machining requirements were extremely demanding.

The actuator shafts are manufactured from tough stainless steel and with a hollow internal diameter larger than the through bore, and the sleeves that go round them are even more difficult to make.

These are machined from solid inconel to a wall thickness of 0.5mm, so work-holding and handling are critical.

The slightest clamping problem could result in an expensive scrapped component.

As Richard Turner, managing director of Turning Technologies, explained, 'We had to develop a process using a hydraulic steady mounted on the lower turret, together with quick-release mandrels to suit various diameters of sleeve on the right-hand spindle so that we could finish machine the outside diameter to an extremely tight tolerance.

Because of the small batch sizes, changeover times are very important, so we put quick change chucks on both the spindles too.' With the system installed and in full production Myers said the whole project has been a great success.

'We have shown our customers we are investing in the supply chain and becoming a partner.

Latest Hyundai-Kia integrated turning and milling centre has been developed for cost-effective 'single-hit' cycles for components produced from bar stock up to 65mm diameter.

Turn/mill centre machines 65mm bar stock Latest Hyundai-Kia integrated turning and milling centre has been developed for cost-effective 'single-hit' cycles for components produced from bar stock up to 65mm diameter. Fitted with a VDI 40, 12 station all-driven turret having +/-40mm Y-axis feed with 16mm tool shank size and M20 tapping capability, the latest SKT 210 SY Integrated Turn/Mill Center from Hyundai-Kia has been developed for cost-effective single hit cycles for components produced from bar stock up to 65mm diameter. Now part of the ever-growing stable of impressive turn/mill centres from C Dugard of Hove, Sussex, UK, this Y- and C-axis subspindle machine has a maximum turning diameter of 240mm diameter at the 15kW, 4,000 rev/min main spindle that carries an 8in chuck as standard.

The subspindle, fitted with a 5in chuck, is powered by a 3.7kW motor giving 6,000 rev/min and a rapid traverse rate of 36m/min.

In order to support milling and drilling cycles at both the main and subspindle positions, 0.001 deg spindle indexing is standard and a manual Q-Setter tool setting probe is fitted to speed toolchange and machine setting.

Axis strokes are 220mm in X, 550mm in Z, 750mm in ZB and +/-40 mm in Y.

The driven tools are powered by 2.7kW motor and the mach

Whether turning or milling the heavy duty machining capability of a mill-turn centre - capable of automatically changing 1m boring bars - provides a powerful platform for high productivity machining.

Yamazaki Mazak's CyberTech Turn 4500M made its UK debut at MACH 2006. This powerful turning centre has a maximum machining diameter of 860mm and, depending on which bed length is specified, a maximum machining length of 3048mm. Heavy-duty machining capability is provided by a main spindle unit with a 37kW/2400 rev/min capability that delivers a 'staggering' 326.3kgf/m (2360ft.lb) of torque.

The CT4500M is more than just a turning machine, though, and is also equipped with a powerful, 11kW, 3000 rev/min milling spindle.

The resulting turning centre is the ideal solution for those companies with a requirement to machine long, large diameter components, typical of those found in the aerospace and oil industries.

The large turret of the CT4500M has capacity for twelve, 32mm square shank tools and can also accommodate boring bars with shanks up to 50mm diameter.

A further plus point is the fact that rotary tools can be located in any of the turret positions and productivity is boosted by the use of random, shortest path, non-lift indexing, which is achieved in a time of 0.4s.

Additionally, two boring bars with 80mm diameter shanks and up to 1m in length can be located in the boring bar stocker.

This feature facilitates the machining of deep bores without the need for time-consuming manual intervention.

For shaft work a servo-driven tailstock, with a stroke up to 2550mm, simplifies setup as its position is recognised by the Mazatrol 640MT Pro CNC, and both its position and thrust settings are controlled by M-code functions.

For further workpiece support automatic programmable travelling steady rests are available.

Furthermore the CT4500M comes with a choice of spindle bore diameter.

As standard, the machine has a 132mm bore and options are available for 185mm, 275mm and 320mm if required, with either a 305mm or 381mm bore through the chuck.

Finally, for a machine of this size agility has not been compromised and rapid traverse rates in the X and Z axes are 24m/min and 30m/min respectively.

The contouring capability, so often required on aircraft and oil industry components, is enhanced by the C-axis, which has a minimum programming increment of 0.001 deg.

Other machines in the CyberTech Turn range offer variations such as the addition of a lower turret or, in the case of the entry-level CT4500, supplied without a milling spindle.

The combination of three turrets, twin spindles and eight axes in a mill-turn centre allows complex components - in for medium volume production - to be machined in a single set-up.

The latest addition to the Yamazaki Mazak Multiplex multi-tasking family of machines, the Multiplex 3 8200Y, further adds to the company's philosophy of developing technology with a purpose. Designed for medium-sized batch size production the Multiplex 3 8200Y benefits from the addition of a lower turret. This, when used in combination with the machine's two spindles and twin upper turrets, provides an extensive capability for simultaneous four-axis machining.

The lower turret, like the two upper turrets, is suitable for fixed and live tooling, giving users even more options when it comes to reducing cycle times by completing as many operations as possible in a single set-up.

The identical horizontally opposed spindles both have outputs of 22kW and generate 35.7kgf of torque and top speeds of 5000 rev/min.

Each has a C-axis and these highly-stable spindle units lend themselves to high speed, high productivity machining.

Aiding these productivity gains is the inherent agility of the Multiplex 3 8200Y.

Rapid feedrate is 50m/min in the X1, X2, Z1 and Z2 axes reducing to 38m/min for the X3 and Z3 axes; 20m/min for the two Y axes, while the two C-axes can run at 400 rev/min.

Acceleration/deceleration in the X and Y axes is 1G.

To maximise utilisation the Multiplex 3 8200Y can be equipped with optional gantry loading or barfeeding.

Alternative enhanced productivity systems such as cut-feeder and shaft loading/unloading systems are also available as options.

Key features among the developments of 'fourth generation', 'one-hit' mill-turn centres is the ability to use 3D-CAD, linear guides in all axes, and 0.0001 deg increments in B- and C-axis.

Yamazaki Mazak's Integrex range, the most widely sold multi-tasking machine tools in the world, epitomise the Done in One concept, with components machined complete in a single set-up. Now, with the introduction of the Integrex Series IV, this concept is further advanced. The fourth generation Integrex series provides the user with a powerful multi-tasking machine tool platform from which to make full use of the machining flexibility that Yamazaki Mazak has created.

One of the key developments on the series IV Integrex machines is the introduction of the Mazatrol Matrix control.

It is this new CNC system that enhances the capabilities of the machine and the interface between it and the operator and/or remote production management and control.

Features such as Intelligent Safety Shield would not be possible without the development of the Matrix control system.

Typical of the range is the all-new Integrex 300-IV ST, which made its UK exhibition debut at MACH 2006.

Key among the developments of the series IV Integrex is the ability to fully utilise 3D-CAD, utilisation of linear guides in all axes, and 0.0001 degree increments on the B and C axes.

This, when combined with the exceptional rigidity of the machine design, results in even better positional accuracy.

The Integrex 300-IV displayed at MACH features opposed spindles and a lower turret with driven tool capability, capable of working on either spindle.

Using the lower turret and upper tool station simultaneously for balanced cutting greatly reduces cycle times, improves turning accuracy and delivers higher quality in terms of surface finish.

Additionally, thanks to the innovative design of the lower turret, the same tool can be used to machine components located in either of the two spindles.

This reduces the total number of tools required, reducing tool costs and improving productivity.

Other developments across the Integrex range include Intelligent Thermal Shield, Intelligent Safety Shield and Active Vibration Control.

Intelligent Thermal Shield has been developed to minimise heat displacement, the machine units producing the minimum possible amount of heat during operation.

Additionally, there is automatic compensation for changes in room temperature.

As a result, machine heat displacement is less than 10 micron with a room temperature change of 8 deg C.

Intelligent Safety Shield highlights any possible collision points when any program is simulated on-screen prior to it being used to actually machine components.

However, Intelligent Safety Shield takes this protection several steps further with the machine being monitored when it is operated in manual mode for instance, during tool measurement with the Tool Eye or when changing inserts.

All machine movements are monitored by the Mazatrol Matrix control, which moves the machine's 3D model simultaneously with the manual data inputs to check machine interference.

Should this occur, the axis movements are stopped immediately, preventing damage to the machine and avoiding costly downtime.

The third innovation is Active Vibration Control, which reduces vibration in all axes during rapid accelerations and results in improved accuracy and surface finishes.

The main specifications of the Integrex 300-IV are a maximum machining diameter of 760mm; maximum machining length of 1524mm; 26kW, 4000 rev/min turning spindles; 18.5kW, 12 000 rev/min milling spindle; and rapid traverses of 38m/min in X/ Z and 26 m/min in Y, with a maximum C-axis rotation speed of 555 rev/min.

Ideally suited to automotive applications, a 26kW inverted spindle turning centre can be used either as a stand-alone machine or combined into an automated two-machine cell.

Where the requirement is to turn and mill large volumes of components Yamazaki Mazak's IVS range is an ideal choice. Ideally suited to automotive applications, the inverted spindle turning centre can be used either as a stand-alone machine or combined into an automated two-machine cell to complete first and second operations in a seamless fashion. The design of the IVS machine delivers a solid platform that lends it to high-volume metal removal and/or hard turning of material in excess of 50 HRc.

The IVS-300M on display at MACH 2006 features a 26kW, 4000 rev/min spindle that can accelerate from standstill to maximum speed in 3.4s and the maximum machining envelope is 350mm diameter by 180mm long.

Rotary tools are driven by a 5.5kW spindle with a maximum speed of 4500 rev/min.

While the IVS 300 is an extremely stable machine it is also extremely agile, with rapid traverse rates measured at 60m/min in the X-axis and 45m/min in the Z-axis.

Acceleration in both cases is 0.9G.

To maintain the highest levels of accuracy and repeatability the IVS 300 employs a scale feedback system on the X-axis.

This system measures the actual distance moved and maintains accuracy over extended periods of operation.

The Z- (spindle) axis is also used to load/unload and facilitate component handling, which in turn eliminates the requirement for gantry load/unload systems.

This reduces both capital costs and the amount of floorspace required.

Also, reflecting the high-volume environment that the IVS machines are aimed at, the 12-position, drum turret can accept rotary tools in any position, and is of the non-lift design that results in a one position index time of 0.2s.

If it is required to index more than one position, the control automatically selects the shortest path to keep non-cutting time to a minimum.

To aid tool setting the IVS is supplied as standard with Yamazaki Mazak's Tool Eye, which can be used to measure tools, register tool data and adjust tool offsets.

Additionally, it can be used to check for tool wear and damage, helping to maintain the machine's up-time.

An NC electric tailstock that delivers quick set-up with no manual intervention was fitted to a 30kW/3300 rev/min turning centre at MACH 2006 - of 420mm diameter x 1538mm machining capacity.

The Quick Turn Nexus series of turning centres from Yamazaki Mazak combines those crucial elements required in today's modern manufacturing environment - namely advanced technology, productivity and value for money. In designing the Quick Turn Nexus range Mazak completed a thorough review of the basic machine components and used state-of-the-art design technology to arrive at a range of turning centres ideally suited to meet the production needs of businesses large and small. At MACH 2006 the range was represented by the recently introduced Quick Turn Nexus 350MY.

This single 30kW/3300 rev/min spindle machine has a machining capacity of 420mm diameter by up to 1538mm long.

It also benefits from the inclusion of a NC electric tailstock that delivers quick set-up with no manual intervention.

The tailstock provides accurate support even for components that can only be supported by low-thrust force.

Positioning and thrust force is achieved using servo motors and are programmable.

Each position in the 12 station drum-type turret can be used for rotary tools, which are driven by a 7.5kW/4000 rev/min motor.

The versatility of the QTN350MY is complemented by the addition of a 150mm Y-axis, further expanding the machine's possible application areas.

Power is matched by agility, with the X and Z axes having rapid traverse rates of 30m/min and 25m/min respectively.

The resulting fast, vibration-free acceleration/deceleration is due to the use of high-gain servo-control and high-power AC servo motors.

Control is provided by the Mazatrol Fusion 640T Nexus CNC unit that features the easy-to-use Mazatrol conversational programming format.

As a result programming time and program length are considerably reduced and editing of existing programs is simplified.

Additional benefits of the Mazatrol Fusion control are its ability to accept modification of programs with minimum editing, cutting conditions are determined automatically by the automatic cutting condition function, edited cutting conditions are stored and recalled when the same material is used again.

High-speed vertical turning machines with linear motor drive that can also perform auxiliary operations such as milling, drilling and tapping now include a 400mm diameter chuck capacity.

Exceptional performance and flexibility have already earned the CTV linear Series a high reputation in the automotive industry and similar high productivity sectors. With specific tooling these high-speed vertical turning machines from DMG can also perform auxiliary operations such as milling, drilling and tapping. This versatility has already enabled manufacturers to reduce unit cost significantly making them much more competitive.

With the addition of the CTV400 linear to the range DMG has opened up this potential to larger diameters.

With a chuck capacity of up to 400mm this top-of-the-range machine has dual-track loading and unloading that can reduce handling time by up to 40%.

The high performance of the machine is complemented by a wear-free linear drive on the 1620mm X-axis that accelerates at 1G for rapid traverses up to 100m/min.

In common with its forerunners, the CTV400 has an integrated spindle drive whose advantages are significantly greater output, high machining forces and no power loss when the spindle is idle.

Maximum torque is 730Nm and swing diameter, 500mm.

High precision and resolution are assured by the machine's direct measuring systems that also dispense with the need for time-consuming reference positioning.

The fast indexing servo turret - 0.21s for 30 deg and with 11.3kW on driven tools - greatly reduces idle times.

This is especially true for eccentric drilling and milling operations for which the turret can be equipped with optional Y-axis featuring a +/-100mm stroke.

To ensure good accessibility and maximum security during three-shift operation, the machine base is divided in two.

The compact and rigid base is of cast-meehanite and supported by a cast mineral foundation.

Unusual in a machine of this class, the design provides superior damping capability and a very high machine weight of 13,000kg.

This stability, in combination with the vertical spindle arrangement that supports optimum swarf clearance, creates the ideal conditions for dry and hard machining.

The inclusion of an optional multi-function T-slot plate in the work area greatly enhances the capability of this heavyweight.

It allows additional tools to be installed in fixed or driven configuration for milling, grinding and boring as well as multi-spindle drill heads or linear tool mounts.

The modular design of this machine allows it to be easily adapted for specific customer needs.

A range of automation options is available to achieve the desired performance.

The machine is controlled by the Windows-based Siemens 840D controller that is of course compatible with the full DMG range of Powertools software support packages including DMG Netservice.

Driven units for the Mori Seiki NL Series of turning machines allow additional machining processes to be carried out in a single setting, reducing downtime and secondary set-up time.

Kennametal's new driven units for the Mori Seiki NL Series of turning machines allow additional machining processes to be carried out in a single setting, reducing downtime and secondary set up time. The units extend the capability of the machine to perform both milling and drilling operations. Setups can be accomplished accurately and efficiently with these units that are either fitted with either the KM interface or a standard ER collet .

When using the units with the highly accurate KM modular interface milling and drilling tools fitted can be precisely pre set offline, the machine can then be set to automatically adjust for the corrected parameters without requiring a test cut.

The savings made in setup time directly translate into higher productivity.

Individual driven units are designed to work specifically with each model variation of the NL series of turning machines to ensure maximum equipment capability.

The driven units feature high precision, wear resistant gears which ensure smooth operation and long tool life.

High-quality seals and O-rings enhance protection against external contamination.Through-coolant capabilities of up to 100 lb/in2 are available.

One of the key design features is high rigidity, enabling higher spindle speeds and feeds and significantly extended tool life.
