5. Eco-friendliness
 Energy saving through
use of LED lights as
standard
Energy saving by eco sleep function
Switches 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
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.
Just need to install a reference sphere as
shown in the guide diagram and then press
the Cycle Start button.
Setting the measurement results to NC
parameters
Effect: Providing higher accuracy for 5-axis
indexing and higher grade for 5-axis
simultaneous machining
7. Geometry error compensation function
For machining with 5-axis machine,
geometry errors (such as the tilt and displacement of the axis
of rotation) significantly affect machining accuracy.
