Abstract
The invention relates to a sapphire sheet edge polishing method. The method polishes sapphire sheet edges through a diamond polishing wheel comprising a diamond wire lock and a base in the steps of Step one: stacking and fixing 50-100 square sapphire in the thickness of 0.2 mm-0.3 mm together; Step two: mounting the diamond polishing wheel on a shaft of a device, wherein the diamond polishing wheel is driven by the rotating shaft of the device to rotate at the speed not less than 2800 turns/minute; Step three: pouring cooling fluid water to sapphire sheet portions to be polished; Step four: slowly moving the shaft of the device to enable the diamond polishing wheel to perform profiling grinding on sapphire sheet edges along the shape tracks of sapphire sheets. The sapphire sheet edge polishing method can be used for grinding to eliminate burrs, dark spots and the like of the sapphire sheets, thereby achieving a very good polishing effect. The water coolant is directly used for removing grindings, so that the economical and environment friendly effects are obtained. Additionally, the method can polish multiple sapphire edges simultaneously, thereby greatly improving the polishing efficiency.
Description
Technical field
The present invention relates to mechanical grinding field, a kind of more particularly, to sapphire sheet edge finishing method.
Background technology
With global electronic consumer products high speed development, some the electronic product enterprises with Apple as representative, constantly
Release great innovation, lead the product of human lives' new paragon.The design of these products produces, and so that a lot of materials has been obtained new
Application, such as sapphire material, with its high hardness and superior Electronic Performance, is used in mobile phone faceplate, home key, shooting
Head mirror head protection screen etc..
Sapphire material hardness is high, fragility is big, after the circular or square thin slice of sapphire ingot cutting, to sapphire sheet
The polishing technology at edge is still bottleneck.If it is larger sapphire edge to be adopted normal diamond grinding tool sapphire edge can be applied
Grinding force, sapphire sheet is easy to fragmentation；According to abrasive pastes polishing fluid etc. because grinding force is little, do not reach ideal effect,
Efficiency is also very low.
Therefore design a kind of finishing method that sapphire sheet edge efficiently can be polished to be particularly important.
Content of the invention
The technical problem to be solved in the present invention is to design a kind of sapphire sheet edge finishing method, realizes to sapphire sheet side
The burr on edge, dim spot play good polishing effect, improve polishing efficiency simultaneously.
For solving above-mentioned technical problem, the sapphire sheet edge finishing method of the present invention, using diamond polishing wheel to indigo plant
Gem piece edge is processed by shot blasting, diamond polishing wheel includes diamond wire tuft and matrix, concretely comprises the following steps:
Step one: the square sapphire sheet that 50～100 thickness is 0.2～0.3mm is superimposed and fixes；
Step 2: diamond polishing wheel is assemblied on equipment axle, drives diamond polishing with the rotation of equipment axle
Wheel rotation, the rotating speed of equipment axle is not less than 2800 revs/min；
Step 3: in sapphire sheet grinding position water flowing coolant, cool down grinding position and discharge abrasive dust；
Step 4: slow mobile device axle makes diamond polishing wheel carry out profiling mill along sapphire sheet shape track to edge
Cut.
Further, diamond polishing wheel excircle is uniformly arranged diamond wire tuft, and diamond wire tuft one end is fixed on base
External circumference and along and its lateral surface vertical direction, the loose free shape length 30～80mm of the other end, between diamond wire tuft between
Gap is beneficial to exclude abrasive dust in time during grinding sapphire sheet, improves quality of finish.
Further, matrix is to become the middle circulus having axis hole by nylon or other plastics, metal material processing.
Further, diamond wire tuft is formed by fixation after the integrated tuft of 10～20 consistent diamond wires of length.
Further, diamond wire is that diamond particle passes through electroless nickel layer and is uniformly fixed on steel wire.
Further, diamond particle is 4～40 μm of diamond single crystal granules through surface metalation of particle diameter, and steel wire is
The high-tensile B alloy wire of a diameter of 0.08～0.5mm.
Further, equipment axle can Double-directional rotary clockwise and anticlockwise.
Further, this finishing method also comprises the steps:
Step 5: fine setting finishing equipment axle movement is adjusted to diamond polishing wheel position, with the speed of 1mm/s along grinding rail
Mark moves, and makes the complete grinding in sapphire sheet edge；
Step 6: after diamond polishing wheel rotates polishing sapphire sheet one week, diamond polishing wheel is set on the contrary
Hour hands rotation polishing sapphire sheet one week.
Further, the step 4 in said method can be substituted with following steps: by sapphire sheet to diamond polishing
Wheel is slowly moved and is rotated with 100 revs/min of profilings.
When in working order, diamond polishing wheel passes through peg-in-hole assembly on equipment axle, drives diamond by equipment axle
Buff wheel is rotated with the rotating speed being not less than 2800 revs/min, the side of the cylindrical diamond wire tuft of diamond polishing wheel and sapphire sheet
Along contact, the attached diamond particle of diamond wire tuft plating does grinding, diamond wire tuft and sapphire sheet side to sapphire sheet edge
Profile copy grinding is realized on edge.
Beneficial effects of the present invention: after such finishing method, grinding can eliminate sapphire sheet edge burr, dim spot
Deng, play good polishing effect, keep face shape consistent, improve product quality, solve a difficult problem for sapphire sheet edge polishing.
Directly it is water-cooled liquid exclusion abrasive dust, economic and environment-friendly.In addition, can achieve simultaneously to multi-disc sapphire during the work of diamond polishing wheel
Edge polishes, and improves more than 3 times of polishing efficiency than oil-soluble abradant polishing solution.
Brief description
Below in conjunction with the accompanying drawings the specific embodiment of the present invention is further elucidated with.
Fig. 1 is the sapphire sheet edge polishing schematic diagram of the present invention.
Fig. 2 is the top view of diamond polishing wheel.
Fig. 3 is the b-b sectional view of Fig. 2.
Fig. 4 is the structural representation of diamond wire.
Specific embodiment
In conjunction with Fig. 1, Fig. 2, Fig. 3 and Fig. 4, the present embodiment adopts the diamond polishing wheel 1 that external diameter is 180mm, axis hole 6 diameter
For 30mm.Diamond wire is by the surface metalation of fixing 5 μm of the particle diameter of electroless nickel layer 7 on the steel wire 8 of an a diameter of 0.12mm
