Tool geometry, glass and steel are mostly brittle materials

Tool geometry: FRP mostly brittle materials. Such as high silica glass fiber reinforced plastic sheet, molding materials and Diamond blade, all belong to such materials. Only appropriate to increase the rake angle, keeping the blade sharp, can be successfully cut fibers. Since the elastic modulus of FRP small, large Polycrystalline diamond, in order to reduce friction, so that light cutting tool rake angle, and the blade as the blade material strength structural limitations Valin superhard cutting tool according to the customer specific design of the tool case angle; strive to achieve the best Abrasive grinding wheel, tool sharpening rich technical experience makes fiberglass after turning finish, after repeated verification, when the choice of turning CDW20 grade fiberglass, using 7-11 degrees angle of 5-6 degrees rake angle 2-3 degrees blade angle can be rough, you can finish, using this angle, the plot is not easy to produce tumor cut, the tool does not vibrate, the process noise;
