5. Eco-friendliness

Energy saving through use of LED lights as standard

Energy saving by eco sleep functionSwitches to sleep mode when the machine remains on standby for a given period of time, turning OFF the servomotor, chip conveyor, etc.

This reduces standby power consumption by nearly 54%.

6. Rotation axis measurement function

Setting the measurement results to NC parameters

Just need to install a reference sphere as shown in the guide diagram and then press the Cycle Start button.

Use of a touch sensor makes it possible to make measurement of the axis of rotation of the table of 5-axis machine in an easy way and a short period of time.

Effect: Providing higher accuracy for 5-axis indexing and higher grade for 5-axis simultaneous machining

7. Geometry error compensation functionFor machining with 5-axis machine,geometry errors (such as the tilt and displacement of the axisof rotation) significantly affect machining accuracy.
