• 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 normailzed, high frequency harden 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 centerlized lubrication system, ensuring proper lubrication and feeding accuracy.
