Non-ferrous materials processing aluminum alloy carbide cutting tap spiral flute tap selection, cutting light, smooth chip; machining brittle materials such as cast iron straight flute tap selection, good rigidity, long life; processing of high hardness steel, made ​​of special geometries and special Taps design optimization can solve high-speed steel cone difficult to solve the problem; processing through hole threads, the choice of blade angle tap, flowing from the front of the chip, and high rigidity than conventional straight flute tap, life should be higher than 2 times. Processing of non-ferrous metal and hard alloy extrusion tap ≥10 ductility of steel, using extrusion tap, you can get a high strength, surface smoother thread, and tap life than cutting tap increased more than 2 times. Particularly small diameter threaded processing, extrusion tap life will be improved by more than 5 times. Carbide drilling and tapping tap processing complex aspect ratio ≤1.5 times threaded through holes, cast iron and aluminum materials, selection of drilling before drilling attack after attack complex taps, so you can put together the perfect combination of drills and taps, improve drilling and efficiency, but also improve the accuracy of positioning, is a good program fully staffed. Carbide thread milling cutters, cutting a wide range of multi-purpose knife, is the most advanced threading tools.
