Features
•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
