Adopt multi grinding head combination and multi-directional cut in type

The method of forming grinding straight track

On line dressing technology of multi group grinding wheel

Linear rolling guide and guide multi grinding head combination device won the national invention patent award.

HZ-078CNC precision linear rolling guide grinding machine is suitable for precision forming of linear rolling guide. The products adopt the method of multi grinding head combination and multi-directional cutting type forming grinding straight track with International Pioneering nature. The company has independent intellectual property rights.
