Abstract
The utility model relates to the technical field of lapping tools, in particular to high-precision sponge sand. The high-precision sponge sand comprises a sponge substrate layer. The upper surface of the sponge substrate layer is provided with a thin layer; the upper surface of the thin layer is provided with an abrasive and glue mixture layer. The abrasive and glue mixture layer comprises a glue layer and an abrasive layer. The middle upper part of the abrasive layer is exposed on the glue layer. According to the sponge sand, the phenomena that abrasive waste is caused and the abrasive layer of a product surface is uneven due to the fact that liquid primer glue and abrasives of which the grain diameters are smaller than pore diameters of sponge foam pores in the adhesive layer sink into voids of the sponge foam pores are avoided. Moreover, the adhesives of the high-precision sponge sand provided by the utility model can reach up to 2500 meshes in maximum grain diameter, so that the surface abrasive layer of the sponge sand is smooth; the use ratio of the abrasives is high; the lapping efficiency can be improved; the processing precision is improved; the surface of a to-be-processed workpiece is more smooth.
Description
Technical field
The utility model relates to milling tool technical field, relates in particular to a kind of high accuracy sponge sand.
Background technology
Conventionally coated abrasive tool used can be divided into two large classes at present with base material classification:
1, paper base material: it is that coated various hard abrasive materials form on paper substrate, and the advantage of this series products is: low price, being easy to produce, is the most traditional production technology; Shortcoming is: easily tear rotten, pulling force is good not, heat radiation is slow, workpiece to be machined grinding discontinuity, Precision Machining are undesirable;
2, cloth base material: it is that coated various hard abrasive materials form on fabricbase, and key property and the paper product of this series products are close, and advantage is: stretching resistance is large, indeformable, grinding force ratio paper substrate series products strong.
Yet current product is to the more and more stricter derivatives, new class base material series products of the precision machined requirement of grinding, sponge substrate sand paper, be commonly called as sponge sand, it is to take sponge elastomer as base material, and that on sponge elastomer, coated one deck abrasive material forms is flexible, elastic force good, rapid heat dissipation, polishing be without the top grade polishing product of scratch.These advantages are that paper substrate and cloth base product do not have.
There is sponge foaming hole in existing sponge sand surface due to sponge substrate in the middle of the process of producing, the little abrasive material of the liquid glue using in manufacturing process and aperture, size ratio sponge foaming hole can infiltrate in the middle of sponge foaming hole, thereby cause the waste of glue and abrasive material, the abrasive material infiltrating in sponge foaming hole is not fully utilized, and shortens the service life of sponge sand.Make abrasive material be roughness on sponge substrate surface, when the sponge sand that uses this type of explained hereafter is processed product, can cause workpiece to be machined to have the scratch of abrasive material.
Particularly for some, need the workpiece of meticulous polishing, need to use the sponge sand of abrasive size more than 1000 orders, yet current sponge sand, its abrasive size can only be accomplished 240 order left and right, seriously restrict the development of grinding workpieces industry, thereby on market, needed the high accuracy sponge sand of a kind of abrasive size more than 1000 orders badly.
Summary of the invention
The utility model provides a kind of high accuracy sponge sand for overcoming above-mentioned defect, the abrasive material on this sponge sand surface is smooth smooth, abrasive material utilization rate is high, and the particle diameter of abrasive material is the highest can reach 2500 orders, can improves grinding efficiency and make the surface flatness, flatness of workpiece to be machined than original further raising.
For achieving the above object, the utility model adopts following technical scheme.
A kind of high accuracy sponge sand, comprise sponge substrate layer, described sponge substrate layer upper surface is provided with thin layer, and described thin layer upper surface is provided with abrasive material glue mixture layer, described abrasive material glue mixture layer comprises glue layer and abrasive material, and the middle and upper part of described abrasive material exposes described glue layer.
Wherein, the particle diameter of the abrasive material in the abrasive material in described abrasive material glue mixture layer is 240-2500 order.
Wherein, the abrasive material in described abrasive material is white fused alumina abrasive material, brown corundum abrasive, silicon carbide abrasive, fused alumina zirconia abrasive material or glass abrasive material.
Wherein, described thin layer is elastic hot melten gel thin layer, elastic plastic film layer or TPU thin layer.
The beneficial effects of the utility model are: a kind of high accuracy sponge sand of the present utility model, and on thin layer, lay after abrasive material glue mixture formable layer, then the thin layer that is provided with abrasive material glue mixture layer is laid on sponge substrate layer, form sponge sand; This sponge sand has avoided the little abrasive material in aperture in size ratio sponge foaming hole in liquid primer glue and abrasive material to submerge in the hole in sponge foaming hole and the rough phenomenon of the abrasive material of the abrasive material causing waste and product surface, and the particle diameter of abrasive material of the present utility model is the highest can reach 2500 orders, make the abrasive material on this sponge sand surface smooth smooth, abrasive material utilization rate is high, can improve grinding efficiency, improves machining accuracy and make workpiece to be machined surface more smooth, smooth.
Accompanying drawing explanation
With accompanying drawing, the utility model is described in further detail, but embodiment in accompanying drawing does not form any restriction of the present utility model.
