The upper type chip conveyor is applied as a standard to efficiently remove chips generated during machining. In addition, the 365 litre (KF5600 II, 6700 II) large coolant tank provides a seamless machining environment even with large amounts of coolant.
Standard application of upper type chip conveyor
- Standard application of upper type chip conveyor
- Standard on-board screw chip conveyor application (forward / backward rotation function added)
- Bed-flushing coolant is applicable (optional)
- Separated an oil-skimmer and coolant tank to keep coolant free of tramp oils
- 58% reduction in spindle vibration compared to existing models
- Spindle acceleration / deceleration increased by 19%
- Hybrid tool lock
- Improved rotary joint quality
Reduced Spindle Vibration And Improved Acceleration / Deceleration
By improving the spindle structure, the vibration and deflection of the spindle are improved, acceleration and deceleration are improved, and the load on the Z-axis feed shaft bearing is reduced to achieve high accuracy and high productivity.
Spindle Oil Cooling (Standard Spindle Over 10,000 Rpm)
By adopting the spindle oil cooling system as an option, a consistent spindle temperature is maintained even during long-term machining, ensuring stable machining ability.
Hybrid Tool Lock
By applying the hybrid tool lock (hydraulic type) through a pneumatic system, the hydraulic motor is removed, reducing heat and noise.
Improved Rotary Joint Quality
The improved integral structure of the rotary joint prevents damage in the spindle motor by oil leakage.

The spindle acceleration / deceleration time is reduced by directly connecting the motor and spindle. To create a high speed for the spindle, the high-precision, high-speed angular ball bearings design creates a wide range of machining with a maximum 15,000 rpm.
The ultra-high precision, high-speed angular ball bearing design that allows the spindle to operate at high speed provides high-speed machining at a maximum of 20,000 rpm, thus displaying excellent performance during machining of mold.
