Lathes

The lathe of the type series TUU 1250 of our strategic partner Koltech is a gantry machine for machining individual wheelset profiles on wheelsets of different diameter ranges. The machine is loaded at ground level (floor level) via a track system.

TECHNICAL SPECIFICATION

Standard equipment of the wheel lathe TUU:

• SIEMENS CNC SYSTEM SINUMERIK 840D
• Digital drive units of saddle motor, integrated with the CNC system. SIEMENS SERVO AC brushless motors
• Input-Output system (PLC), based on PROFIBUS solution
• TOUCH AND GO operator’s panel, supported by visualization of technological cycles in operation
• Hydraulic power pack and hydraulic apparatus
• Oil cooler
• Swarf protecting guards
• Operation and Maintenance Manual
• Diagnostics of disturbances in machine work
• Audio-visual warning and signalling system
• Hinged platform with rails
• Measuring heads

Applications:

• Reconditioning of wheel profile of used wheelsets
• Turning of wheel profile of new wheelsets
• Exposing of the ring, securing the wheelset wheel tyre
• Facing of inner and outer faces of wheel tyres
• Facing of active surface of brake discs, axle-mounted or wheelmounted by means of optional equipment
• Frictionless linear guideways with needle bearing cages for saddle and slide travels
• Hydraulic drive motors for rollers drive, for differing the speeds of particular driving rollers at simultaneous preservation of equal distribution of torque.
• Frequency inverters for the regulation of speeds of main drive pump motor
• Measuring heads for achievement of perfect machining results
