One of the hot job operations of tungsten carbide burrs mould is high speed machining, called for HSM. HSM has changed the traditional tough or tedious steps: annealing, milling, thermal treatment, ablation or electrical discharge machining, hand polished( buffing ). To achieve customer requirements for product finish, more and more manufactures has been adopting this technology.


1. Introduction to materials and coatings


Tool material must be harder than substitute material. The greater the difference in hardness between the work piece material and cutter material, less tool wear, the longer the tool’s service life. The tool material must be guaranteed to have oxidation resistance, on account of the high local temperature.


2. Requirements for clamping seat


Because of the need for high spindle speed in processing, youd better use HSK-A and HSK-E system. The clamping flange is mounted on the spindle head and the clamping seat has definite mechanical support in the Z direction, as a result, it does not drag into the main axis because of increased centrifugal force, under higher rotation speed.


It increases in square as the speed increases. It means that the centrifugal force caused on spindle with 42000rmp speed is 441 times as much as spindle with 2000rmp speed in the same unbalanced situation. So, unbalance of tool holder device has particularly obvious adverse consequences in high speed machining.

The chuck holder with good damping characteristics is capable of bringing good results for rough machining process. Extremely high rigidity and repeated accuracy can be achieved with reduced joint. Various kinds of the transfer twists of reduced knife base rest with design structure of clamping equipment. They can be quite different.


The foreground of china Die industry has been relating with hard alloy carbide rotary file, we are supposed to always keep a watchful eye and concern.
