Modern carbide rotary file processing, HSM is widely used as an important technology. By means of applying HSM, you can milling all kinds of soft and hard materials, suitable for most of the precision mold , high precision copper and graphite electrode. There is a lot if discussion around this technology, common ones are as follows:


How is the principle of high speed milling different from the traditional one?


What requirements does high speed milling have for cutting tools and holders?


Will high speed milling replace EDM?


1. The condition of top speed peeling


As the rotational speed increases to a certain extent, the temperature and cutting force of cutlery will gradually decrease instead. The phenomenon is used in high speed milling technology.


2. The contrast of tradition and super-speed


The traditional milling material removal area is large but slow. The temperature is high. Low precision of finished products. The tool wear fast. Produce a poor surface.


The high speed whittling material removal area is small but fast. The temperature is low. High precision of finished products. The tool wear slow. Produce a fine surface.


3. The dispersion ratio of HSM reservoirs


70 percent of the heat source is taken away by iron dust and oil mist, 10 percent is taken away by cutter, 20 percent is absorbed by work piece.

4. The applied range of HSM


To match the spindle specification ensure the stability of machining and safety, tool diameter shall not exceed 16mm. Compared to conventional milling, the removal rate of HSM is correspondingly comparatively small. It fits finding and pattern perfectly. Can be applied to water, fine and other new processing areas. It is a new concept of soft and super hard materials processing method.


5. HSM requirements for cutting tools


Tool vibration directly affects the surface quality obtain by machining. Therefore, it is vitally important to maintain uniform cutting force. In the HSM working, avoiding to trigger shake. The influence of cutter adjacent geome try on cutting force is as follows:


  •        Good concentricity makes for keeping cutting edge loaded on balance.

  • Large overlap of cutting edges is helpful to obtain even cutting force.

  • Short cutting length is beneficial to obtain better rigidity.

  • Core cross section is in the best condition, stress concentration is mininal at the notch.


The market of hard alloy steel rotary file for deburring mould: HSM is getting better and better.
