CNC Technology of Thread Milling Tools

With the popularity of CNC machine tools, thread milling technology is increasingly used in the machinery manufacturing industry. Thread milling is a three-axis linkage of a CNC machine tool, which uses a thread milling cutter to perform spiral interpolation milling to form threads. The cutter makes a circular movement on the horizontal plane, and linearly moves a thread pitch in the vertical plane. Thread milling has many advantages such as high processing efficiency, high thread quality, good tool versatility, and good processing safety. There are many types of thread milling tools currently in use. This article intends to analyze and introduce several common thread milling cutters from the perspectives of application characteristics, tool structure, and processing technology. 1 Ordinary machine clamp type thread milling cutter The clamp-type thread milling cutter is the most commonly used and low-cost tool in thread milling. Its structure is similar to that of the ordinary clamp-type milling cutter. It consists of a reusable toolholder and a blade that can be easily replaced. If you need to machine taper threads, you can also use special tool holders and blades for taper threads. This blade has multiple thread cutting teeth. The tool can process multiple thread teeth at a time along the spiral line. For example, use one A milling cutter with 5 2mm thread cutting teeth can process 5 thread teeth with a thread depth of 10mm along the helical line. In order to further improve
