VMC has latest manual guide CAM on board

Of ten machines shown under power, a twin pallet VMC has the latest manual guide CAM while two updated two axis lathes will be hard turning aerospace components to 'super precision' finish.
Visitors to Ward Hi-Tech on stand 5280 will see a total of ten machines, under power, ranging from standard two-axis CNC lathes through to powerful multi-axis driven tool turning centres; large capacity vertical turning lathes through to horizontal and vertical machining centres and universal head bed-type and travelling column CNC milling centres. Among them will be several new models and others that benefit from significant upgrades. * New - the Dah Lih DMV-800 twin pallet travelling column vertical machining centre, featuring a Fanuc OIMB control system with latest manual guide cam software and colour graphics, benefits from a large rotary pallet arrangement and is capable of performing both heavy-duty and high speed machining.

Axis travels of 800mm (X) and 560mm (Y and Z) are supplemented by a spindle speed of between 80 and 8000 rpm and a 32-position toolchanger.

This model will be shown machining a stainless steel valve body under heavy-duty conditions as well as demonstrating the high-speed machining of aluminium, highlighting the versatility of the DMV-800.

CME's FS-0 ram-type universal head machining centre with Heidenhain I530 control provides a rigid platform from which to make best use of its speed and accuracy.

With its 1200mm (X) and 750mm (Y and Z) axes travel, 5000 rpm spindle and universal head the FS-0 will be machining a mould for an automotive alloy wheel, a process involving heavy-duty cutting in steel.

* Updated - new from Doosan will be the updated S280N and S310N two-axis lathes.

The S280N features a maximum turning diameter of 280mm combined with a turning length of 320mm and a maximum spindle speed of 6000 rpm.

Manufactured with rigid box ways, 10 position turret and axis travels of 160mm (X) and 330mm (Z), the S280N will be demonstrating its ability to 'hard turn' an aerospace component to a 'super precision' finish.

The larger S310N has axis travels of 185mm (X) and 500mm (Z) with a maximum turning diameter of 310 mm and length of 480mm, while the turret increases to a 12-position unit.

Promoting the rigid box way design, the S310N will be demonstrated cutting a steel billet under heavy-duty conditions.

Two axis Horizontal and Vertical lathes - Ward Hi-Tech will also be showing the Doosan S670L heavy-duty two-axis slant bed lathe, which with a maximum turning length of 1850mm is ideal for shaft work.

The S670L has a maximum chuck size of 762mm and a turning diameter of 670mm, while its 50HP main motor and four-speed gearbox delivers full power from 64 rpm.

Confirming its suitability for heavy-duty application, it can accommodate 32mm2 shank tooling and up to 60mm diameter boring bars.

Vertical turning is also catered for with the Doosan V550 single-spindle, two-axis vertical turning lathe.

With a maximum turning diameter of 550mm (610mm chuck) and turning length of 610mm, the V550 provides ease of loading and a heavy-duty machining capability.

The V550 has become a well respected model throughout the automotive industry and will be demonstrated producing commercial vehicle brake drum components for a well known name within the industry.

* Multi-axis turning centres - Doosan's S310SMLY six-axis turning centre features a y-axis turret arrangement along with c-axis control of the main and sub-spindles.

Other features include a 12-station VDI driven tool turret, maximum turning diameter of 310mm and length of 750mm and a 65mm bar capacity.

This model will be shown producing complex VDI toolholders complete, in an example of 'one hit' machining throughout the show.

The second Doosan multi-axis lathe on display will be the Z290SMY eight-axis twin turret, twin-spindle turning centre.

The main and sub-spindles are fully synchronised and can be fitted with a combination of chuck or collet chuck.

The 12-station turrets can accommodate up to six driven tools in any combination while the main and sub spindle both have full c-axis capability.

Maximum turning diameter is 290mm and length is 580mm with 65mm bar capacity.

The machine at MACH will be coupled with a magazine bar loader and will highlight its y-axis capability with a thread milling operation.

The Z290SMY is a high-speed producer of volume components ideally suited to around the clock production requirements.

* horizontal machining centres - Ward Hi-Tech will be represented in this sector by the Doosan HM45H twin-pallet horizontal machining centre.

The machine is equipped with twin 450mm2 pallets and a 60-position fast moving toolchanger.

Axis travels on this moving table machine are 600mm (X) and 560mm (Y and Z), with the X and y axes sharing an H section carriage.

Another feature of this machine, which will be demonstrated producing an aluminium mobile 'phone holder from solid (roughing and high-speed finishing), is its two-speed built-in 30HP motor and its numerous optional features, which make it ideal for integration into a variety of alternative production cells.
