Machine features

  • Spindle material is SCM415 full hardened through carbonizing heat treatment.
  • NST#30/R8 spindle with 3HP variable speed motor (250 VS) and NST#40 spindle with 5HP variable speed motor (305 VS) (inverter motor is an available option).
  • Spindle quill drive box is transmitted by ballscrew for better precision.
  • Essential castings are made of high grade of Meehanite cast iron, which has been stressed and relieved to provide a rigid machine structure.
  • Standard with 10”x54” table, hardened and ground.
  • Table T-slot is precision ground to exact tolerance.
  • Precision ballscrews on X&Y axes (select machines).
  • X&Y slideways and gibs are coated with Turcite-B to provide smooth and wear resistant surface.
  • 1:2 ratio timing belt pulleys on XY axes to increase drive torque.
  • Box way design on Y & Z (knee) axes leads to better rigidity. (305 VS)
