Background technology
Along with global electronic consumer products high speed development, take Apple as some electronic product enterprises of representative, constantly release has innovation, leads the product of human lives's new paragon.The design of these products is produced, and make a lot of material obtain new application, such as sapphire material is with its high hardness and superior Electronic Performance, is used in mobile phone faceplate, Home key, cam lens protection screen etc.
Sapphire material hardness is high, fragility large, and sapphire ingot is still bottleneck to the polishing technology at sapphire sheet edge after cutting into circular or square thin slice.If adopt normal diamond grinding tool can apply larger grinding force to sapphire edge to sapphire edge, sapphire sheet is easy to cracked; According to abrasive pastes polishing fluid etc. because grinding force is little, do not reach ideal effect, efficiency is also very low.
Therefore design and a kind ofly can seem particularly important to the finishing method that sapphire sheet edge carries out efficient polishing.
Summary of the invention
The technical problem to be solved in the present invention is design a kind of sapphire sheet edge finishing method, realizes the burr to sapphire sheet edge, dim spot plays good polishing effect, improve polishing efficiency simultaneously.
For solving the problems of the technologies described above, sapphire sheet edge of the present invention finishing method, adopt diamond polishing wheel to carry out polishing to sapphire sheet edge, diamond polishing wheel comprises diamond wire tuft and matrix, and concrete steps are:
Step one: the square sapphire sheet being 0.2 ~ 0.3mm by 50 ~ 100 thickness is superimposed and fixes;
Step 2: diamond polishing wheel is assemblied in equipment axis, drive along with the rotation of equipment axis diamond polishing to take turns and rotate, the rotating speed of equipment axis is not less than 2800 revs/min;
Step 3: in sapphire sheet grinding position water flowing cooling fluid, abrasive dust is also discharged in cooling grinding position;
Step 4: slowly mobile device axle makes diamond polishing wheel carry out profile copy grinding along sapphire sheet shape track to edge.
Further, diamond polishing wheel excircle is evenly arranged diamond wire tuft, diamond wire tuft one end is fixed on matrix excircle and edge and its lateral surface vertical direction, the loose free shape length of the other end 30 ~ 80mm, get rid of abrasive dust in time when gap between diamond wire tuft is beneficial to grinding sapphire sheet, improve quality of finish.
Further, matrix is by nylon or other plastics, the middle circulus having axis hole of metal material processing one-tenth.
Further, diamond wire tuft fixedly forms by after the consistent integrated tuft of diamond wire of 10 ~ 20 length.
Further, diamond wire is that diamond particle is evenly fixed on steel wire by electroless nickel layer.
Further, diamond particles is the diamond single crystal particle of particle diameter 4 ~ 40 μm through surface metalation, and steel wire is diameter is the high-tensile B alloy wire of 0.08 ~ 0.5mm.
Further, equipment axis can clockwise and counterclockwise Double-directional rotary.
Further, this finishing method also comprises the steps:
Step 5: inching equipment axis moves and regulates diamond polishing wheel position, moves, make the complete grinding in sapphire sheet edge with the speed of 1mm/s along grinding track;
Step 6: rotate polishing sapphire sheet after one week at diamond polishing wheel, is set to inhour mutually by diamond polishing wheel and rotates polishing sapphire sheet one week.
Further, the step 4 in said method can substitute by following steps: sapphire sheet slowly moved to diamond polishing wheel and rotate with 100 revs/min of profilings.
Time in working order, diamond polishing is taken turns by peg-in-hole assembly in equipment axis, diamond polishing wheel is driven to rotate with the rotating speed being not less than 2800 revs/min by equipment axis, the diamond wire tuft of diamond polishing wheel cylindrical contacts with the edge of sapphire sheet, diamond wire tuft plates attached diamond particle and does grinding to sapphire sheet edge, and diamond wire tuft and sapphire sheet edge realize profile copy grinding.
Beneficial effect of the present invention: after adopting such finishing method, grinding can eliminate sapphire sheet edge burr, dim spot etc., play good polishing effect, holding surface shape is consistent, improves the quality of products, solves a difficult problem for sapphire sheet edge polishing.Direct water coolant gets rid of abrasive dust, economic environmental protection.In addition, can realize during the work of diamond polishing wheel doing polishing to multi-disc sapphire edge simultaneously, improve polishing efficiency more than 3 times than oil-soluble abradant polishing solution.
