Precision ground and supersonic frequency hardened bed ways is designed in double wall structure, giving super rigidity. The spindle system is high in rigidity and accuracy. The design of the main drive is optimized and the gears in the headstock are precision ground. The noise of the machine is low.
There is no need for change gears. The machine can turn about 200 kinds of metric, whitworth, module and D.P. threads. An automatic stopping device is used to realize automatic stop for the machine of a certain length workpiece, which is safe and reliable with braking device providing quick and effective stop while operating.
