1. Polisher of canister form vibration it is put the part hold the canister form on bedspring (or bowl form) inside mouth container, make through some kind of device container produces fluctuation and right-and-left vibration, make spare parts and abrasive medium chafe each other thereby and the goal that achieves polishing. The advantage of oscillatory polisher is to be able to machine larger part, the efficiency of polishing is compared common roll light to be gotten high much, and still can be opposite in polishing process the exterior quality of the spare parts undertakes checking. But it is unwell the spare parts at treatment nicety and brittleness, also cannot acquire very shining plane. The method that makes container produces vibration has a variety of, vibrating motor can be installed in the bottom of clingy container, drive by electric machinery have slant place is serious piece drive axis will come true; The electromagnetism system that also can use 50Hz~60Hz frequency to work will arise. The oscillatory frequency of oscillatory polish is in normally 15Hz~60Hz (use 20Hz~30Hz commonly) , the limits of oscillatory extent is 2mm~10mm (use 3mm~6mm commonly) . Polisher of canister form vibration has 3 kinds of configuration (3-12 seeing a picture) . graph 3-12(a) instead of U form canister pursues (B) or graph (C) form, can avoid the circumfluence appearance of part of the part when working, form evener flow. The drive system that produces vibration can make following changes: (1) the 3-12(b that be like a graph) and (C) be shown, convert two axis of rotation, make spare parts and abrasive medium have evener with quicker grinding action. (2) with prejudicial annulus replace slant place is serious piece, in order to get bigger and stable oscillatory action. (3) will slant place is serious piece or prejudicial annulus put in the two side end the canister or cylindrical shell upside. Machine of canister form vibration can add section chief to amount to 12m, wide the part with the large part that amounts to 2m and complex form. In machining a process, can undertake checking to machining quality, change at any time the spare parts of treatment. The appearance of polisher of canister form vibration is like graph 3-13 and graph 3-14 place to show. 2. The appearance of polisher of vibration of polisher bowl form is like bowl form vibration graph 3-15 and graph 3-16 place are shown. Graph 3-16 with device of automatic sift out. The structure of polisher of bowl form vibration is shown like graph 3-17 place. The container installation of form of a bowl or tire form is on bedspring, put spare parts, abrasive by certain proportion next, grind agent and water. By container center on vertical axis slant place is serious piece transmit vibration to container, make the spare parts inside container and abrasive medium make helix motion with certain way, mutual grinding and the goal that achieves polishing. Of the amount that increases person abrasive when be operated actually and workpiece bulk than be 2:1~6:1, rough machining is 2:1, finish machining is 6:1. Add even at the same time wear a lotion, its cent is grinding and blame grinding two kinds. Wear a lotion to be not grinding sex, its function basically is to maintain abrasive clean, keen and can free grinding. Grinding sex grinds an agent to help polishing action through further cutting action, its dosage is normally 0. 2 ％ ~0.
4% (the capacity is compared) . In addition, add water even, the quantity of water wants proper, it is 4%~5% normally (the capacity is compared) , overmuch meeting creates irregular flow, make abrasive and part detached; If water measures inadequacy, criterion lubricity becomes poor, interrupt the flow of abrasive even, make spare parts and abrasive sere. Nextpage and photograph of machine of canister form vibration are compared, the action of machine of bowl form vibration kisses quite and, because this is attainable more bright and clean surface, but efficiency wants a few lower. Watch 3-4 listed the metabolic circumstance of surface roughness of surface of around of polish of polisher of bowl form vibration. The 3-17 that be like a graph (B) be shown, when on container installation blocks feed group and should setting screen network, in bowl form container, the part that grinding ran a week and abrasive medium arrive after blocking feed group to be in, had been served screen net, can make spare parts and abrasive medium depart automatically thereby. Machine of bowl form vibration cannot machine large part, this is its place that is not worth greatly. When polishing combines the bowl form vibration of a few different abrasive together, with respect to the face that can gain tall brightness. 3. Oscillatory polish uses the choice vibration polish of abrasive to answer to requirement of place of the appearance according to workpiece, size, treatment, treatment and workpiece material pledge and choose appropriate abrasive. The abrasive that uses normally has carborundum, corundum, alumina and pottery and porcelain 4 kinds big, its appearance can divide into: ① is globose; ② is cylindrical; ③ is inclined cylindrical; ④ triangle; ⑤ inclined triangle; ⑥ square. It can be right alloy of steel, aluminous, alloy steel, aluminium alloy, zinc, bakelite and plastic the product that waits for material to be made undertakes machining, have the effect of exceedingly good purify burr and polish. The surface roughness of the surface after treatment can raise two 3 level. Watch 3-5 listed the technology of of all kinds abrasive is characteristic, express what 3-6 listed abrasive and arenaceous bead eye are spent to contrast watch. CNC Milling
