Poreba TCF heavy centre lathes

Poreba TCF HEAVY CENTRE LATHES 
BASIC PARAMETERS
In their basic version the TCF series
3 guideways bed 250 275 300 heavy centre lathes thanks to the innovative
Max. torque on spindle 40,000 Nm mechanical solutions and the advanced control systems are Max. weight of workpiece between centre 30 tonnes the multi purpose lathes that guarantee productive rough and finish machining. Turning length
PURPOSE
The TCF series lathes are designed for workpiece machining in the range of turning in accordance with their specifications, especially for machining of large size shafts. When delivered with special equipment they can operate as the horizontal machining centres with
turning, drilling and milling capabilities. They can be equipped with an automatic turret, tool attachments, tool and workpiece measuring systems, controlled C axis, workpiece steady rests.
CONTROLSYSTEM
The application of the state of the art CNC system allows for automatic, precise and productive workpiece machining according to a program.
