What's the best roughness for machining cast aluminium ?

PCBN is a new superhard cutting tool material with high hardness, high thermal stability and high chemical stability, which is second only to diamond in hardness. When PCBN cutting tool is combined with turning instead of grinding technology, the metal removal rate can be significantly improved, and the same or better surface roughness can also be obtained. In addition, it is convenient to change the tool by turning instead of grinding, and there is no necessary time to correct the grinding wheel, so the machining efficiency is higher. At present, PCBN cutting tools and turning instead of grinding technology have been widely used. Practice has proved that the processing time and cost are reduced by at least 70%. Zhengzuan adds a new PVD coating to the original PCBN tool, which has strong adhesion to prevent the coating from falling off and realize stable processing. After the coating is added, the wear resistance of the tool is improved, thus prolonging the serviceli life. The lower su

High precision: The axial adjusting bolt and dynamic balance adjusting bolt achieve perfect runout precision. The unique design of the clamping mode of the cartrige ensures the machining precision firmly and reliably. High efficiency: Lightweight Design & firm structure, capable of high-speed machining, optimized edge material selection and design, and faster cutting process. High tool life: The internal cooling channel design improves the tool life of the edge and optimizes chip removal. The cutter body is made of high-strength material, which is more wear-resistant. High value: Stable processing, excellent processing surface. PCD cartrige is durable, replaceable and grindable.

PCD universal ball end milling cutter is suitable for non-ferrous metals such as aluminum and aluminum alloys, copper and copper alloys, fiber and metal composites, glass, engineering ceramics, engineering plastics, stone and wood.
