Description
Technical field
The invention belongs to precision processing technology fields, are related to a kind of glass polishing machine superhard mill and correction-plate.
Background technique
Glass polishing machine is a kind of equipment for throwing technique processing ultraprecise plane using ring, is mainly used for optical glass, silicon, KDP
Crystal, the isoplanar grinding and polishing of ultraprecise metal die, are widely used in aerospace, national defence and precision machinery field.It adopts
The Ultra-precision Turning of the standard round optical flat (diameter 150mm) as plane survey benchmark, 1 grade of optical flat can be realized by throwing technique with ring
Flatness is up to 50nm.There are mainly two types of the mills and correction-plate of glass polishing machine, and one is Dali millstone plates, and one is cast iron mills
Disk.When the nonmetallic materials such as processing optical glass, silicon, KDP crystal, Dali millstone plate is commonly used as rigid support disk, is then existed
Add polishing pad or pitch paying on the millstone plate of Dali, forms polishing disk；When processing metal parts, cast iron mill is commonly used as grinding
Disk.The material of correction-plate is general consistent with the material of mill.
Due to the defects of cast iron materials thermal expansion coefficient is higher, material is partially soft, hardness is uneven, in process of lapping itself
Wear also more serious and abrasion unevenly, to cause the precision stability of cast iron mill and correction-plate poor, grinding precision does not have
The precision of Dali millstone plate is high.However, Dali millstone plate is due to oil suction water suction mutability and hardness is not high, it is also not suitable for directly
Process metal parts.Therefore, the superhard mill and correction-plate for developing while being suitable for metal and nonmetallic Polishing machining, become
The task of top priority.
Diamond (mohs hardness 10) in super hard abrasive, cubic boron nitride (mohs hardness 9.7) and boron carbide (rub
Family name's hardness be 9.3) be one of three kinds of materials most hard on the known world.Boron carbide is low with density, intensity is big, high-temperature stable
Property and the good feature of chemical stability, are mainly used in plate armour, bulletproof jacket and many industrial application product of tank.In addition,
Boron carbide is compared with diamond and cubic boron nitride, and manufacture is easy, is low in cost, thus use is more extensive.In some aspects
Expensive diamond can be replaced, grinding, turning, drilling, in terms of application.
For other super hard abrasives, intergranular can form the gap of similar grinding wheel after boron carbide high temperature sintering, this is right
Highly beneficial oilstone particularly suitable for production precise finiss is cut in highly-efficient processing, storage lapping liquid and appearance.However due to
The restriction of the factors such as Mold Making is at high cost, sintering space is limited, processing difficulties, boron carbide oilstone on the market be mostly size not
Rectangle oilstone greater than 300mm.Common are the rectangular oilstone of 200mm × 200mm × 20mm, 200mm × 50mm × 25mm and
100mm × 25mm × 5mm strip rectangle oilstone.Boron carbide oilstone on the market cannot be used directly to manufacture circular mill and repair
Positive disk.

The splicing of type oilstone is made；Complete regular hexagonal prism oilstone is A type oilstone, and other types of oilstone passes through straight line by A type oilstone
Cutting technique obtains: the midpoint line along A type oilstone bottom surface one vertex side adjacent thereto is cut, face in remainder two parts
Biggish product is Type B oilstone；The lesser part of area is intercept the maximum isosceles triangle that a bottom surface apex angle is 120 ° three
Prism is c-type oilstone；Diagonally symmetrically cutting obtains two D type oilstones to one A type oilstone；One A type oilstone is along bottom surface phase
The two vertex lines for being spaced 1 vertex, which are cut, can be obtained 3 E type oilstones.
The superhard oilstone of regular hexagonal prism used is sintered molding with the same mold, it is ensured that the size of all oilstones is consistent
Property.
One mill needs (3) 18, A type oilstone, the position vacancy of an A type oilstone of middle；Need Type B oilstone
12, c-type oilstone and each 6, D type oilstone；One correction-plate needs 7, A type oilstone, needs 6, E type oilstone；
One glass polishing machine needs a mill and a correction-plate, needs the superhard oilstone sum of blanking sintering regular hexagonal prism altogether
It is 42, wherein 25, A type oilstone, remaining 18 oilstones are cut into 12 Type B oilstones, 6 c-type oilstones, 6 D type oilstones
With 6 E type oilstones.
Further, the superhard oilstone of regular hexagonal prism is made up using boron carbide micro powder of high temperature sintering, or using diamond or
Cubic boron nitride micro mist is made up of resin or metallic bond sintering.
To any change that the production method of the material of oilstone or matrix, the quantity of oilstone and incomplete oilstone is made, still exist
Within protection scope of the present invention.
The beneficial effects of the present invention are provide one kind by disc Dali stone substrate and the superhard oilstone group of regular hexagonal prism

Specific embodiment
By taking PL12 type glass polishing machine as an example, the structure and size of boron carbide superhard mill and correction-plate are illustrated.
PL12 type glass polishing machine grinding wheel diameter is 1200mm, according to the inscribed circle diameter of regular hexagonal prism oilstone bottom surface regular hexagon
For 1/6 requirement of grinding wheel diameter, the inscribed circle diameter of regular hexagonal prism bottom surface regular hexagon is 200mm.In view of boron carbide is micro-
The cost of powder, the design height of all oilstones are 20mm.According to the size of regular hexagonal prism oilstone, sintering mold is manufactured, is examined simultaneously
Consider the influence of the factors such as thickness of diamond blade when oilstone after heating shrinks and cuts.
Selecting granularity is that the boron carbide abrasive material of 2000 mesh is at least sintered 42 regular hexagonal prism oilstones, wherein A type oilstone 3 totally 25
Part takes 12 A type oilstones 3 by being cut into 12 Type B oilstone 4 and 6 c-type oilstones 5, takes 3 A type oilstones 3 diagonally
Wire cutting is at 6 D type oilstones 6；Take two pieces A type oilstone 3 along bottom surface separately 1 vertex three lines cutting can be to 6 E types
Oilstone 7.
Being spliced into diameter with 18 3,12, A type oilstone, 4,6, Type B oilstone c-type oilstone 5 and 6 D type oilstones 6 is about
The subcircular disk body of 1200mm, then sticking at diameter is 1200mm, with a thickness of on the discoidal marble grinding disc substrate 2 of 150mm,
Superhard mill is made.Since the linear velocity of mill center point area is lower, should be avoided using the region processing, therefore mill is hit exactly
Between an A type oilstone position vacancy.
It is spliced into the subcircular disk body that diameter is about 600mm with 7 A type oilstones and 6 E type oilstones, then sticks at diameter
For 610mm, with a thickness of on the discoidal marble correction-plate matrix 1 of 80mm, superhard correction-plate is made.Correction-plate avoids as far as possible
Superhard oilstone disk body size is greater than correction-plate Dali stone substrate size.
When superhard mill is modified, for the dressing efficiency for improving mill and correction-plate, grain can be used through Buddha's warrior attendant bigger than normal
Stone, cubic boron nitride or boron carbide grinding agent carry out whole to researching, and then gradually decrease the partial size of abrasive material, mill and are repaired with improving
The plane precision of positive disk；Concretion abrasive is more sharp in the superhard oilstone just modified, and can directly adopt dry grind or only liquid feeding body
It is wet grind, the micron powers such as aluminium oxide, zirconium oxide, cerium oxide, chromium oxide equipped with hardness no more than oilstone hardness can also be used
Grinding agent carry out Polishing machining.It is lower than the grinding agent of mill oilstone sintered abrasive grain hardness using hardness, advantageously reduces superhard
The abrasion of mill and correction-plate, this is highly beneficial for the precision stability for improving superhard mill and correction-plate.
