Description
Technical field
The present invention relates to the one kind drawn needed for excellent link in a kind of Sapphire Substrate manufacture process of LED industry use is special
Cutter.
Background technology
After the main simple transformation by traditional vertical machining center of rod drawn by sapphire at present, blue precious using collet clamping
Stone draws excellent knife root, carries out drawing rod processing by the vertical method chiseling hole machined.The sapphire of this kind of form is drawn excellent knife and is adopted axle
Hole clamping position, the cutter tooth at edge of a knife position sinters crescent shape into using diamond cuprio, and then cutter tooth is uniformly welded on base steel and draws
On excellent cutter hub, form some deeper chip areas.
Excellent knife drawn by above-mentioned sapphire, and excellent knife root centrifugal force in the case of running up drawn by collet clamping sapphire
The deformation causing is big.Deeper chip removal mouth leads to sapphire to draw in excellent knife grinding process, and cutting fluid cannot pass through, washes away grinding sword
Portion and be expelled directly out it is impossible to effectively take away the cutting edge powder of grinding generation, lead to crystal bar finished surface to grind wound, percent defective is high.
Content of the invention
The present invention draws sapphire in rod motion for sapphire and draws the problem that excellent cutter exists, and provides a kind of new structure shape
Excellent cutter drawn by the sapphire of formula, draws excellent efficiency and yield rate to improve crystal.Hard and crisp sapphire processing generally adopts grinding
Mode, the present invention, according to wheel grinding technological requirement, proposes to solve the scheme of above-mentioned technical problem：
Excellent knife drawn by sapphire, including the cutter head being sequentially connected, draws excellent cutter hub and handle of a knife, and cutter head is fixedly mounted on draws excellent cutter hub
Front end, draw excellent cutter hub have for cooling liquor stream enter axially through annular limbers, wherein：Before drawing excellent cutter hub rear end and handle of a knife
End face fit, draw excellent cutter hub and be provided with several axially extending and mutually corresponding positioning shaft hole with handle of a knife, and draw excellent cutter hub and
Handle of a knife is crossed positioning by positioning shaft hole and is fixed.
For optimizing technique scheme, the concrete measure taken also includes：
Above-mentioned excellent cutter hub rear end of drawing is provided with in-line or cross locating groove, and the front end of handle of a knife is provided with and locating groove
The positioning card convex matching, when drawing excellent cutter hub rear end and fitting with handle of a knife front end face, locator card convex clip enters prevents knife in locating groove
Handle relatively rotates with drawing excellent cutter hub.
Above-mentioned cutter head front end is provided with the annular edge of a knife, and several edge of a knife grinding swords are ringwise laid on the annular edge of a knife,
And be fixedly connected in the annular edge of a knife of rear end insertion of edge of a knife grinding sword and with the annular edge of a knife, annular is stretched out in the front end of edge of a knife grinding sword
The edge of a knife, the gap between adjacent edge of a knife grinding sword is connected with annular limbers, between high-pressure cooling water is between edge of a knife grinding sword
Gap imports edge of a knife grinding sword working position, washes away machining area.
By granularity 80 mesh, the diamond JR-3 of concentration 100% and binding agent is integral sintered forms for above-mentioned edge of a knife grinding sword,
Binding agent is bronze.
The above-mentioned annular edge of a knife and the main part of cutter head are welded and fixed by profile of tooth, and postwelding grinding makes joint face smooth.
Above-mentioned edge of a knife grinding tread degree about 3mm, each edge of a knife grinding sword stretches out the of length no more than of the annular edge of a knife
1.5mm, makes to form shallow chip area between adjacent edge of a knife grinding sword.
After the above-mentioned annular edge of a knife of edge of a knife grinding sword insertion, by welding, edge of a knife grinding sword is fixed as one with the annular edge of a knife
Body.
On the basis of the above-mentioned peripheral side by handle of a knife, the no more than 0.02mm that beats of cutter head.
Above-mentioned edge of a knife grinding sword is equidistantly laid on the annular edge of a knife, and the spacing between adjacent edge of a knife grinding sword is 3mm
To 4mm.
The sapphire of the present invention is drawn excellent knife cutter hub and is connected by axis hole positioning with handle of a knife, and what end face was fitted crosses location structure shape
Formula, to improve cutter rigidity, the deformation that when reducing High-speed machining, centrifugal force produces.Draw excellent cutter hub rear end and pass through locating groove and knife
Handle coordinates, and prevents handle of a knife and draws excellent cutter hub and relatively rotate, and reduces cutter head and beats.Edge of a knife position adopts shallower rhone, by force will
Water under high pressure imports grinding sword working position, washes away machining area, takes away grinding heat and cutting edge powder.Edge of a knife position cutting edge is adopted
Use diamond JR-3, granularity 80 mesh, concentration 100%, binding agent is the bronze selecting bond strength high, grinding sword in edge of a knife position is adopted
After integrally sintered, it is welded by profile of tooth in the annular edge of a knife making with 45 steel, fixing very firm, postwelding grinds
Cut the tool precision it is ensured that high.
Compared with prior art, the invention has the advantages that：4 inches of cutters of location and installation mode are crossed in 4000r/ using end face
Under the rotating speed of min, the deformation that centrifugal force produces is 4.6 μm, compares collet clamping installation direction, and deformation reduces 10 times, and
And the circular runout of cutter head position is less than 0.02mm and each cutting tooth action is less than 3 μm, cutter precision itself greatly improves, and protects
Demonstrate,prove the required precision to emery wheel for the grinding technique.Using shallower rhone knife edge structure, formed good using water under high pressure
Punching bits environment, effectively prevents cutting region from holding bits situation and occurs, and take away heat in metal cutting in time.Meet the final realization of above-mentioned condition and draw rod
The high linear speed of processing, roughing feed grinding, improves in the case of ensureing yield rate and draws excellent efficiency.Knife-edge portion is burnt using overall
Form the intensity that type cutting tool shape effectively improves cutter tooth position, prevent from drawing the excellent situation damage cutter of forging a knife being manufactured into during knife, carry
High cutter life.Facts have proved that drawing excellent efficiency using new construction cutter than traditional structure cutter improves more than 3 times.
