Detailed Product Description

Most key parts of the automobile in the present age are made of die-casting aluminum alloy with complex structure, shape and many step-formed holes which itself has higher quality requirement on roughness, roundness, concentricty, and no flash. In order to meet the machining requirement, our company developed PCD forming step reamer by utilizing imported high precison grinder and form grinding techniques. The PCD forming step reamer makes all the cutting edges have excellent cutting behavior under different maching loads, guarantees the dimensional precision and roughness of the workpiece machined,eliminates the disadvantages of carbide reamer, such as adhering to the reamer, poor resistance to wear, variable dimension, poor quality of machined surface, prolongs the service life of cutting tools and reduces the production cost
