Sequential machining of the front and reverse ends of one component or simultaneous machining of two separate components are equally effective on the new Takamaz XW-180 twin-spindle CNC lathe.

Sequential machining of the front and reverse ends of one component or simultaneous machining of two separate components are equally effective on the new Takamaz XW-180 twin-spindle CNC lathe from Yuasa Warwick Machinery. The majority of Takamaz lathes, in particular the twin-spindle models, are supplied to world markets with automatic component load / unload equipment, and the UK is no exception, hence the importance which Yuasa places on the introduction of this new machine. It has a number of features, which enhance precision and its configuration can be customised with a choice of automation according to end user requirements.

A key development is the machine's special bed structure, which incorporates a vibration damping system.

This is said to allow widely different machining operations to be carried out at the two identical spindles without accuracy being compromised.

Vibrations caused by roughing at one spindle will not, it is said, affect the finish obtained at the other.

A further aid to accuracy is the use of large diameter bearings in both spindles.

Configuration of the machine is as two fixed-headstock lathes sharing a common bed, with work transfer effected either manually or by an integrated gantry system.

As well as being served by an 8-station turret, either spindle can be optionally equipped with a 2-station end drilling unit and/or a programmable tailstock.

This offers the possibility of complete machining of long, shaft-type components.

Maximum turning diameter on the machine is 210 mm with turning length up to 160 mm.

Power of the spindles is 7.5 kW maximum, offering steplessly variable speeds in the range 200 to 3,500 rev/min.

Two versions of the Takamatsu áW load/unload system are available for use with the machine.

The 'CR' model has been developed for components up to 80 mm diameter by 160 mm long and 1.5 kg in weight, while the 'SRQ' version can handle components up to 120 mm diameter by 50 mm long and weighing 2.0 kg.

Each offers a load time cycle of under eight seconds and a quick-change gripper system to suit different components.

Various other component handling systems including bar magazines and part stockers allow the machine to be customised for a wide range of production applications.
