This series of lathe machine bed is the overall box-shaped structure, adopts high standard cast iron (HT300) one molding casting, after the second aging treatment, it has good stability, guide-way width (400mm), good rigidity, anti-vibration ability; Processed by medium-frequency hardening and machined by the imported rail grinding machine , to ensure a long life, high precision and good maintainability.
This series of lathe machine has big diameter of spindle which is supported by precision heavy-duty bearings, which makes the rotation steadily. they can perform not only the heavy turning but also the finish turning. Automatic forced circulation lubrication makes the transmission system is flexible and effectively cool. Automatic segmented speed control by the M code, the segment automatically variable speed by S code selection control, achieved stepless speed and constant linear cutting. X and Z use precision ball screw ensures a high processing accuracy, positioning accuracy and accuracy of retention. CNC system uses the internationally renowned FANUC, SIEMENS or China GSK980TD AC servo control system, axis-Z uses large torque AC servo motor, directly connected to ball screw by non-backlash elastic coupling. X-AC servo motor is associated with a ball screw by 1: 1 toothed belt. Before delivery all the lathe machines use the British RENISHAW laser detector for precision testing, so the lathe machine has a high positioning accuracy and repeat positioning accuracy. All the lathe machines are equipped with electric turret, free lifting, tool change quickly and easily, there are vertical 4 and 6 station and horizontal 6 station and other electric turret for choose.
