CNC lathes, with a choice of bed lengths up to 10m, feature large spindle bores are suited to machining 'oil country' components as well as other long bed work.

 

There are five models in XYZ Machine Tools' 'extra large' capacity CNC lathe range, including the latest 'large bore' XYZ XL 1200 and smaller, mid-range, 'large bore' XYZ XL 1100.

 

Both machines feature a 410mm/16.15in diameter spindle bore, making them ideally suited to 'oil country' work.

 

They offer a choice of bed length up to 10m, so a lathe configuration can be set up for a customer's specific requirements.

 

All machines in the XL range are controlled as standard by the Siemens 840D conversational ShopTurn CNC.

 

The control system has 'easy to navigate' menus and comprehensive 'Help' screens.

 

So operators lacking specific DIN/ISO knowledge can soon learn how to program the machines.

 

Graphical support and integrated profile calculator help pogram any contour quickly and easily.

 

Other aids include simulation and many other functions to speed programming and program verification.

 

A 10m bed XL lathe would weigh 22 tonnes and the 'large bore' XYZ XL 1200's footprint is 13180mm (for a 10m bed length machine) by 2500mm.

 

The equivalent footprint figures for the smaller, lighter, 'large bore' XL 1100 are 12930mm by 2300mm.

 

The solid ribbed one-piece 692mm-wide cast iron bed and base casting of the 50HP/3-250 rev/min 'large bore' XYZ XL 1200 ensures maximum rigidity during heavy-duty machining.

 

All models have 'vee and flat' bedways to give a large bearing surface that contributes to a high standard of accuracy and surface finish.

 

The headstock is of equally rugged construction, featuring induction hardened and precision ground gears and precision taper roller bearings and support roller bearings that guarantee spindle rigidity and concentricity.

 

Similarly, a substantial tailstock with three clamping points prevents movement when machining components between centres.

 

Model designations denote the swing diameter in mm over bed, with a swing over the cross slide of 950mm (XL1200)/750mm (XL 1100).

 

Standard equipment includes a four-jaw independent chuck, four-way toolpost, joystick control for rapid movement, automatic lubrication of all gears and bearings (ensuring thermal stability, quiet running and long life), flood coolant and electro-magnetic spindle brake.

 

Optional equipment includes fixed or travelling steadies, quick change toolpost or electrically-operated or hydraulically-operated turret, and chip conveyor with cart.
