The maximum allowable weight of the lathe spindle is based on the bearing load capacity. If the weight of the chuck and workpiece combination is too large, the bearing may be overloaded. For those machining tasks with danger beyond the limit, this danger may determine people’s choice of workpiece fixture. The weight of jaw chuck is often larger than that of the same spring chuck. Therefore, the spring chuck is the appropriate choice when the weight needs to be controlled.<\/p>\n\n\n\n

Therefore, NC High-speed machining process can be generally divided into: rough machining – semi finishing – corner cleaning – finishing and so on. For parts with high precision requirements, it is sometimes necessary to carry out secondary and semi finishing, and then finish machining. After rough machining, the parts can be cooled naturally to eliminate the internal stress caused by rough machining and reduce deformation. The allowance left after rough machining shall be greater than the deformation, generally 1 ~ 2mm. During finish machining, the finished surface of parts shall maintain a uniform machining allowance, generally 0.2 ~ 0.5mm, so that the tool is in a stable state in the machining process, which can greatly reduce the cutting deformation, obtain good surface machining quality and ensure the accuracy of products.<\/p>\n\n\n\n
