Carbide cutting tap machining non-ferrous materials such as aluminum spiral flute tap selection, cutting brisk, smooth chip; processing brittle materials such as cast iron straight flute tap selection, good rigidity, long life; processing of high hardness steel, use a special groove and special Taps design optimization can solve high-speed steel cone difficult to solve the problem; threaded through holes, the choice of blade angle tap, chips outflow from the front, and high rigidity than conventional straight flute tap, life should be higher than two-fold. Extrusion processing of non-ferrous metal carbide taps and ductility of steel ≥10, using extrusion tap, you can get high strength, surface smoother thread, and tap life than cutting tap increased by more than two-fold. Especially small diameter threaded processing, extrusion tap will increase the life of more than five-fold. Carbide drill attack complex tap processing aspect ratio vias thread ≤1.5 times, cast iron and aluminum materials, selection of drilling before drilling attack after attack complex taps, drills and taps so you can put together the perfect combination of improved drilling and efficiency, but also improve the accuracy of positioning is a good program to serve multiple purposes. Carbide thread milling cutter, cutting a wide range of multi-purpose knife, is the most advanced of the thread processing tool.
