螺纹铣削加工刀具技术（Cutting tool technology for thread milling） Thread milling tool technology.Txt do not believe in forever, do not have expectations, do not need a promise, when you can no longer own, the only thing you can do is to make yourself not to forget. The prince is able to export and unitary vertical beauty is because the prince eyes star heart I can export Huan Qiuxing what with the popularity of CNC machine tools, machining thread milling technology is more and more used in machinery manufacturing industry. Thread milling is the three axis CNC machine tools, the use of thread milling spiral milling interpolation and the formation of thread cutter in the horizontal plane each week in circular motion in a vertical plane is linear movement of a pitch. Thread milling has many advantages, such as high processing efficiency, high thread quality, good tool versatility and good machining safety. At present, there are many kinds of milling tools for thread cutting. In this paper, some common thread milling cutters are analyzed and introduced from the point of view of application characteristics, tool structure and machining technology. 1 ordinary machine clamp thread milling cutter The clamp type thread milling cutter is the most commonly used and inexpensive tool in thread milling. Its structure is similar to that of the common machine clamping cutter. It is composed of a reusable cutter bar and a replaceable blade. If the machining of taper thread, special cutter can also be processed by cone screw rod and blade, the blade is provided with a plurality of thread cutting teeth, along the spiral machining tool can be processed once a week from multiple threads, such as milling cutter with a 5 2mm thread cutting teeth, teeth along the screw thread rotary line processing for a week can be processed with 5 thread depth 10mm. In order to further improve the machining efficiency, multi blade clamping type thread milling cutter can be used. By increasing the number of cutting
