Description

Technical Field

[0001] The utility model relates to a vibration-resistant forming slot end milling cutter, in particular to a vibration-resistant forming slot end milling cutter, belonging to the technical field of vibration-resistant forming slot end milling cutters. Background Art

[0002] End mills are mainly used for machining planes, steps, grooves, forming surfaces and cutting off workpieces on milling machines, while shock-resistant forming groove end mills are used to reduce the lateral vibration amplitude of the milling cutter when it is cutting at high speed.

[0003] A high-speed anti-vibration carbide end mill with announcement number CN220216853U includes a cutting edge, one end of which is provided with a cutting edge, and the other end is connected to a tool holder. The top of the cutting edge of the device is provided with a blunt round structure, so that the cutting edge is passivated compared with the ordinary structure, which can increase the damping of the cutting system during the processing, thereby enhancing the stability of the cutting edge, and further resisting the high-frequency chatter generated by the rebound of the material. In addition, the milling force amplitude of the variable pitch milling cutter is small in the entire frequency range, thereby fundamentally reducing the self-excited vibration and forced vibration.

[0004] In the above technical solution, the cutting edge is connected to the tool holder as a whole through the cutting edge, so that the stability of the cutting edge is enhanced. However, after long-term use, the cutting edge and the cutting edge will wear out. At this time, the cutting edge and the cutting edge need to be replaced. Since the cutting edge and the cutting edge are an integrated structure with the tool holder, they need to be replaced as a whole, which wastes the user's use cost. For this reason, we provide a vibration-resistant forming groove end mill. Utility Model Content
