Graph 3-20 is to rotate the principle graph of type polisher polish. It is secure the spare parts go up in one axis of rotation, and immerge fills those who have abrasive slop to rotate inside the canister, because spare parts surface is moved quickly of slop cast the goal that grind action and achieves exterior polish. Rotate the abrasive that polishing uses has a variety of, the most commonly used is oxidation molybdenum mine arenaceous, connect water and chemical accelerant to undertake wet condition polish from inside the conduit of canister center upside. Regard as when dry state polish, wait for medium of mixture composition abrasive with carapace of fine abrasive and broken corn core, Hu Tao. Its handling time exceeds 20min rarely, be in commonly 30s less than. Because the spare parts is,secure the possibility that go up in rotary column coming back and won't have mutual collision individually, because of this kind of equipment very agree with cage of treatment gear, chain wheel, bearing the spare parts that wait for nicety and is afraid of collision, can go to its burr, round and gain very fine face. Its machine this kind of specific treatment facilities efficiency is inferior, cost is higher. Apply to only commonly other group by group the circumstance that polishing equipment cannot satisfy a requirement. CNC Milling
