Product Advantages Technical Parameter Manufactured Product

1. The high-precision multi-station tool grinding machine for micro drills and mills, with a new grinding machine design concept, is a 4-station CNC rotary continuous automatic tool grinding machine ;
2. Based on the 4 working head rotary table, this machine can be used for high volume production of carbide micro drills;

3. 3 of these 4 stations is disigned for grinding and the 4th station is for loading and unloading workpieces. This machine is the only rotary continuous automatic machine designed specifically for the production of micro drills;
4. Machining cycletime: ≤ 15 seconds per workpiece, and the accuracy and dimensional repeatability: less than 0.002 mm for mass production;
5. Tool clamping technology can guarantee the runout of workpiece:less than 0.002mm;
6. Closed loop control of all axes;
7. Automatic high speed loading and unloading robot system;
8. Simple and intuitive programming.
