• The machine base’s inner ribs are calculated and deployed through Finite Element Analysis, which reduces unnecessary mass and boosts the structural rigidity to the optimum level.


    • The C3 grade pretensioned ball screws are directly coupled with servo motors,featuring high servo response and superb positioning accuracy.


    • The inner bore of headstock casting is fine-bored to embrace the spindle cartridge firmly and precisely. Also the symmetric external ribs minimize and stabilize thermo expansion. The entire unit features low vibration, low noise and low temperature rising.


    • The STM MH series is high performance CNC lathe with box guideways. Coated with Turcite and grooved with lubrication oil channel, the box guideways design allows the most rigid performance to deal with the heavily cutting.
