Abstract

The utility model relates to a diamond dry grinding piece, comprising a base body and a metal grinding layer fixed on the outer surface of at least one surface of the base body, wherein the grinding layer is formed by certain quantity of ring-shaped convex blocks which are uniformly distributed. The diamond dry grinding piece has the benefits of being good in softness, good in heat dissipating performance, strong in grinding force, high in wear resistance, high in grinding efficiency, good in polishing effect, and low in cost, saving the emery material, being easy to discharge scraps when in grinding and cutting, being not easy to block, being widely applicable to grinding and cutting of materials of stone, glass, ceramics, synthetic materials of resin, PVC and the like, and having no dyeing and burning to processing materials.

Description

A kind of diamond dry grinding disc

Technical field

The utility model relates to the grinding materials and grinding tool field, is specifically related to a kind of diamond dry grinding disc.

Background technology

Diamond abrasive belongs to super hard abrasive, its microhardness 8000～10000 kgf/millimeters ²In suitability for industrialized production, be widely used in recent years.Be to carry out during rapidoprint, because of its working (machining) efficiency height, processing effect good (can polish exigent material) form the cutting material into first-selection in the mode of micro-cutting.In the prior art, diamond disk and soft abrasive disk are mostly adopted in the processing of the plane of crisp and hard material.Nonmetal hard brittle material grinding modes such as concrete floor, stone material, glass, pottery have wet-milling and dry grind two kinds.The wet-milling mode is lower to the resistance to elevated temperatures requirement of abrasive disc, and most abrasive discs can both reach requirement, but will consume a large amount of cooling waters, and produce large amount of sewage, are unfavorable for environmental protection; The dry grinding mode does not need cooling water, can avoid the sewage discharge problem, and the dust that dry grinding produces also can be collected, process operation is convenient, but dry grinding, especially long-time dry grinding is very high to the resistance to elevated temperatures requirement of abrasive disc, in case abrasive disc resistance to elevated temperatures deficiency, then can smolder in grinding process burns, abrasive disc and phenomenons such as machined material surface discolouration and adhesion residue, the adverse consequences that grinding can not be proceeded in serious also can causing, abrasive disc and machined material are damaged and scrap.

Existing diamond dry grinding disc, in the majority with concentric circles radial pattern and two kinds of spiral radial patterns.But existing this type of dry grinding disc pliability is good inadequately, poor heat radiation.Disclose a kind of diamond that is used for hand electric polisher among the Chinese patent literature CN 2710835 and cut abrasive disc, has plane disc substrate, be provided with axis hole in the middle of its disc substrate, periphery is provided with the ablation layer, disc substrate is provided with the countersunk head through hole of annular spread, in order to be fastened on end face on the machine shaft in addition and have screw hole and diamond to cut the corresponding flange head of abrasive disc countersunk head through hole to be connected; Disclose a kind of clearance type diamond among the CN 2587621 and cut abrasive disc, the boart boart working lining that it comprises the chassis and is coated in chassis surface, this working lining is made up of some intensive uniform projections, it can be used for cutting, the polishing of stone material, metal, glass, glass, pottery, resin synthetic material, PVC material etc., have that the diamond consumption is few, cost is low, be difficult for to stop up advantage such as heat radiation better, chip removal is unobstructed, and cutting polishing speed is fast; Disclose a kind of novel diamond circle abrasive disc among the CN 201147904, the lines of its circle abrasive disc two sides is symmetry fully, and the abrasive disc both sides are stressed impartial with friction during cutting function, and vibration amplitude reduces.

Summary of the invention

The technical problems to be solved in the utility model provides that a kind of pliability is good, thermal diffusivity good, and the diamond dry grinding disc that stock removal is big, the grinding time is long, resistance to elevated temperatures is good.

For solving the problems of the technologies described above, the technical solution adopted in the utility model is:

A kind of diamond dry grinding disc comprises basic unit's body and is fixed on the diamond grinding layer of at least one outer surface of basic unit's body that the ring-type projection that described grinding layer is fixed on basic unit's body by evenly arranging constitutes.

Described basic unit body center offers installing hole.

Described basic unit body is discoid.

Described bump height is 2～10mm.

Spacing between the described projection is 1～10mm.

Diamond grit in the described diamond grinding layer is any one among 50#, 100#, 200#, 300#, 400#, 500#, 800#, 1000#, 2000#, 1500#, 3000#, the BUFF.

The utlity model has actively useful effect:

1. pliability is good, perfect heat-dissipating, and grinding force is strong, the rub proofness height, the grinding efficiency height, polishing effect is good;

2. the diamond dust materials are economized, and cost is low, and polish when cutting, and chip is easy to discharge, and are difficult for stopping up;

Perfect heat-dissipating;

3. be widely used in the grinding and the cutting of materials such as stone material, glass, pottery, resin synthetic material, PVC, and rapidoprint is not dyeed, do not burn.

Description of drawings

Fig. 1 is a kind of structural representation of diamond dry grinding disc.
