Auto Measurement System

Using automatic measurement system, you can be able to find the inclination measurement, AR correction and reference point. EXCETEK provide a probe to measure the accuracy and auto-calibrate the precision mold before machining which reduce the pre-processing time.

With macro instruction, it automatically measure and correct the reference point to improve the mold processing accuracy. After processing, the accuracy test is performed directly on the workbench, which saves the repeated disassembly time of the workpiece and avoid the processing errors caused by repeated disassembly.
