Measuring

DHF has been newly equipped with advanced tool measuring machine from ZOLLER. With CCD camera and Saturn image processing system,

the instrument can inspect various types of tools ans cutting.

The accuracy can reach 0.002mm.

Tool measruing can assure the accuracy of the workpieces and also the tool life.

Laser Engraving

After strict quality control, all end mills are engraved code number and "DHF"logo for verifying good quality.
