Carbide rotary burrs can replace small grinding wheels with handles in a huge part of the work, and produce dust environmental pollution; the first production and processing are cost-effective, high smoothness, and can produce high-precision abrasive molds of various shapes; second The service life is long, the cutting performance is 10 times higher than that of spring steel, and the wear resistance is more than 200 times higher than that of small grinding wheels; and it is convenient to grasp, easy to apply, reliable, slow down labor efficiency, improve office environment; high overall economic benefits , The comprehensive production cost can be reduced by up to 10 times. Carbide rotary burrs are generally hand-held electric or pneumatic tool drives (also can be used on CNC lathes). The speed ratio of electric or pneumatic tools is generally 6000-50000 rpm. Note: Be sure to clamp the CNC blade clamp in the application. The drilling method is preferably up-cut milling to prevent reciprocating cutting. But avoid cutting while working
