PC-12S-NC

Precision spindles: The GW spindle and the RW spindle are precision machined and made from alloy steel, processed with normalization, aging, and heat treatment, then proceed to sub-zero treatment, finally finished after precision machining and grinding.
Feed screw: The feed screw is manufactured from alloy steel. It’s also normalized, high frequency hardens, and precision ground in order to have high feeding accuracy and excellent wear resistance.
Pressure switch: When starting the GW and RW spindle, this pressure switch allows starting only when oil enters into bearings thereby providing safety protection for the spindle bearings.
Lubrication system: The automatic lubricator provides lubrication to the GW spindle. Also, all slideways are lubricated by a centralized lubrication system, ensuring proper lubrication and feeding accuracy.
