Description

Technical Field

[0001] The utility model relates to the technical field of milling cutters, in particular to a variable diameter thread milling cutter. Background Art

[0002] Thread milling technology is increasingly used in mechanical manufacturing, which has promoted the development of the industry. The application of thread milling requires attention to the applicable workpiece shape, favorable processing plan and reliable quality thread milling cutter. Only through the comprehensive use of thread milling technology can the advantages of thread milling be fully utilized and effective results be achieved. At the same time, it also allows the performance of machine tools to be fully demonstrated and promotes the production capacity of thread milling cutters.
