Features

•三點支特式主軸並採用精密級斜椎軸承

The spindle is 3 pointed type which is supported by precision tapper roller bearings.

Cross slide with heat treatment and are finished with precision grinding to increase working life over 3 times.

Leasd screw is designed with immersing style, which reduces abradsion.

INTERNAL STRUCTURE OF HEADSTOCK

Headstock box uniquely designed to use high class iron and all running parts are lubricated by presure pump.Forced lubrication system is employed for headstock to ensure its lubrication and cooling when high speed revolve and keep accuracy lasting. Gears in the headstock are made of chromium molybdenum steel (SCM-21), treated with cementation and precise grinding to provide smooth and quiet running.

THE STRUCTURE OF BASE

One piece of base is made of meehanite casting, which by harden heat treating and precise grinding.Main motor and coolant pump are devied under base which is safe and saves time.
