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.

Just installing a reference sphere in accordance with the
guide diagram shown on the display, and then pressing the
Cycle Start button can facilitate making measurement and
setting it to the NC.Effect: Providing higher accuracy for 5-axis indexing and
higher grade for 5-axis simultaneous machining
Rotate the A and C axes to make measurement at several measure points.
Calculate compensation parameters on the software side,and then set the results on the NC.
