Max. gripping force : 56 kN /Max. rpm : 6,000 rpm

Fine adjustment possible by NC adjustment(Resolution 1kN level)

Surface roughness improved by more than 3 times compared to hydraulic pressure(no cylinder)

Removal of hydraulic unit - realization of clean environment(Removal of hydraulic tank, hydraulic motor and cylinder)

Electric driven main spindle CNC lathe system

/ Possible for all type of chuck

/ By removing the hydraulic cylinder, no vibration effect due to hydraulic pulsation during machining, so the surface roughness is improved by 71.3% compared to the hydraulic pressure.

Measure the hydraulic system and power consumed underthe same conditions.

The average power consumption of the electric driven system measured over 10 minutes(20 cycles) is 0.101 kW, and the hydraulic system is 1.06 Kw, reducing 90.5% level.

① Measured power consumption after applying 23kN of draw bar thrust (based on 6-inch Lathe)

② Measured hydraulic system with power consumption of the hydraulic drive motor (20 cycles)
