SSS control ensures high machining stability and quality with
virtually no effects resulting from cutting shape or speed.
Smooth surfaces can be achieved even when small steps
exist in a path, and machining time can be reduced by 5 to
30% relative to conventional systems.
High-accuracy machining is realized by controlling each axis
so that the tool center point moves linearly at a commanded
feed rate even if the rotary axis moves in linear interpolation.
High-accuracy Machining with
Complete Nano Control
High-quality Machining with
Balanced Accuracy and Speed
Complete nano control enables high-speed and high-accuracy
machining at a maximum fine-segment feed rate of 168kBPM.

High-grade 5-Axis Machining
Control Technology
A high-speed error-compensation function is used for
controlling the spindle and servo, enabling accurate tapping.
High-speed and High-accuracy
Tapping
When a possibility of interference is detected on a machine
model, the motor decelerates to a stop before interfering.
The part to interfere is displayed in a different color.
