Description

Technical Field

[0001] The invention relates to the technical field of screw processing milling cutters, and in particular to an indexable milling cutter for processing a small-diameter screw raceway. Background Art

[0002] A milling cutter is a rotary tool with one or more teeth used for milling. Each tooth cuts off the excess of the workpiece intermittently in sequence during operation. Milling cutters are mainly used to process planes, steps, grooves, forming surfaces and cut off workpieces on milling machines.

[0003] The existing cyclone milling cutter is mostly used in the process of screw raceway processing. However, during the processing of the current cyclone milling cutter, when the blade of the milling cutter becomes blunt, the milling cutter needs to be replaced. At this time, the machine needs to be stopped, the milling cutter needs to be disassembled and replaced, or the milling cutter needs to be polished and then replaced. The milling cutter blade cannot be automatically changed and polished, resulting in cumbersome use of the milling cutter and low tool changing efficiency, which leads to low processing efficiency of the screw.
