Frisby Metal Collapsible Stick Handle

The center hole of the positioning fine reference plane should be processed before rough machining, and the process of repairing the center hole should be arranged after quenching and tempering and before grinding. After quenching and tempering, the center hole is repaired to eliminate the heat treatment deformation and oxide scale of the center hole. Before grinding, the center hole is repaired to improve the accuracy of positioning the fine reference surface and reduce the surface roughness value of the tapered surface. When formulating the technological process of the transmission shaft, the processing of the secondary surface should also be considered while considering the processing of the main surface. When semi-finishing ￠52mm￠44mm and M24mm outer circle, it should be turned to the size specified in the drawing, and the chamfers and threads of each undercut should be machined at the same time; each keyway should be milled after semi-finishing and before grinding. This can ensure a more accurate positioning datum when milling the keyway, and can avoid damaging the finished outer surface when milling the keyway after fine grinding.
