Modern automotive gearboxes are designed to reduce weight and versatility. More and more die-cast aluminum alloys are used to make complex gearboxes with a number of stepped shaped holes. Surface roughness, roundness, cylindricity, concentricity, and burr-free quality requirements are very strict.
In order to meet the need for efficient and high-precision machining of multi-step forming holes in gearboxes, the Japanese company has developed a PCD forming step reamer. The tool uses high-quality PCD insert material and uses high-precision forming grinding technology to ensure excellent and consistent dimensional accuracy and surface roughness of the cutting edge shape, so that all cutting edges have excellent cutting performance under different processing loads. The tool can achieve satisfactory processing quality in use, eliminating the disadvantages of the sticking knife, prolonging the tool life and reducing the processing cost by half.
