Multiple Functions Status Display

Trouble Shooting

When the alarm appears, the screen will display the malfunction message and trouble shooting procedure enabling the operator to solve problems to shorten the shutdown time.

Circular Work-Piece Measurement

By measuring the A, B, C three points coordinates the circular work piece's center point can be correctly calculated.

CNC Parameter Optimization

From rough cutting to fine finishing, the operator can select various cutting modes based on the working condition, and then set the allowable error and work piece weight to obtain the optimum parameter.

Advanced RectangularWork-Piece Measurement

The rectangular work piece program can calculate the center coordinate and the slant angle of a work piece by measuring point A, B, C, D and E coordinates; the calculated center coordinate can be inputted into the work piece coordinate program ( G54 ~ G59 ).

Auto. Tool Length Measurement

Graphic user interface is easy to use, and up to 12 tool length measurement can be done in one button, which saves programing time and lowers operation error.
