In mould treatment, rough machining, semifinishing machining uses milling cutter of head of ball of machine clip type extensively already. But when finish machining, traditional treatment pattern still is to use milling cutter of integral hard alloy. Cutting tool price is high, answer grind more difficult, need recoat layer. Answer more primary cutting tool has the cutting tool life after grinding and precision bigger difference. Outstanding company is aimed at Japanese black these problems, through research and experiment, development goes individual precision work to use head of ball of machine clip type to carry milling cutter, fill the blank in mould treatment, already used extensively in Japan, United States and Europe at present. Its characteristic is as follows: 1. Ministry of center of blade of good by treatment surface quality cutting uses the big chamfer that hold bit to design, because this has the good sex that discharge bits and cutting sex, can achieve very tall surface precision. Can be amounted to by treatment surface Ra0. 4 the following. 2. Cutting tool production precision and treatment precision are tall because use unique fixed structure, make bit installs clip to originally, stability is taller, deserve to go up again the razor blade of high accuracy (point production precision is ± 0. 006) , the integral precision that raises cutting tool thereby (precision of circular arc of the point after assembling is ± 0. 008) . 3. Bit holds clip it is convenient, good to repeat precision individual clamp unit, the outfit of bit is placed and disassemble more convenient, and repeat precision tall (patent application) . 4. Cutting tool service life grows bit to use the JC5010 with newest DIJET and JC5025 material to plant. The surface uses TiAlN and TiCN crisscross multilayer and compound coating, its cutting performance is very steady. JC5010 has extremely tall wearability, JC5025 can suit bigger percussive is machined. 5. Manufacturing efficiency tall steel linear velocity of dot of the cutting when treatment is recommended for 200m ／ Min, and linear velocity of its cutting dot is recommended when cast-iron treatment for 250m ／ Min, feed can amount to 1mm ／ Rev. 6. Reduce milling cutter of head of ball of cost whole hard alloy to be in answer after grinding, repeat when using, the ability after needing recoat layer achieves former service life and efficiency. Because the user is in answer the production requirement that adjusts very will inaccessible primary cutting tool, cause cutting tool life to suffer an effect greatly. And use this cutting tool, will avoid the difficult problem of above, improve cutting tool service life thereby, reduce cost. Compare with photograph of milling cutter of head of ball of integral hard alloy, the machine clip of this cutting tool does not grind bit to show very old economy again. 7. Breed range of all ready, application is wide by cutter hub diameter classification has 8, 10, 12, 16, 20, 25, 30, 32. By cutter hub length classified criterion has short model (S) , medium-sized (M) , long model (L) .
