The utility model comprises a basal body and a plurality of grinding bodies, wherein the grinding bodies are fixed on the basal body at intervals; the grinding bodies are also arranged on the grinding surface of a grinding head at intervals, wherein the basal body is best made of bonding material with certain flexibility; the grinding bodies are best made of diamond alloy material. The utility model has the characteristics of high grinding performance, easy processing, low cost and high grinding processing quality and can be suitable for large-scale grinding processing.

Description

Bistrique

Technology neck city

The utility model relates to the grinding tool of nonmetallic materials such as a kind of stone material, ceramic material, and particularly relating to a kind of is the grinding tool of mill body with the diamond alloy.

Background technology

In the processing of nonmetallic materials, often relate to nonmetallic materials are carried out grinding process, normally on mill, fix several bistriques and finish this operation as grinding tool.Generally the bistrique of Shi Yonging adds bonding agent by normal sands materials such as carborundum, quartz sand, corundum and constitutes, this bistrique adhesive strength is low, grinding efficiency is poor, bistrique service time is short, environmental pollution is serious, and labour intensity is big in the use, energy consumption is higher.

In order to improve the grinding performance of bistrique, utilized diamond as abrasive material afterwards, it is joined sinter diamond alloy carcass in the metal dust into, and carcass made tile-shaped formation bistrique, but this tile-shaped bistrique face that whole grinding face contacts with machined object in grinding process is bigger, reduced to participate in the pressure of grinding unit's diamond alloy, thereby weakened the grinding force of diamond alloy bistrique; Simultaneously, when this bistrique is made grinding tool, be be welded on it on metallic plate or direct sintering on metal derby, be fixed on again and form on the connector, exactly because adopted this metal connected mode, cause diamond abrasive tool in grinding process with between the machined object, to form rigidity and contact, immalleable, usually occur destroying the machined object surface because of impulsive force is excessive, cause the phenomenon that lacks the limit unfilled corner, have a strong impact on the quality of grinding, can't use in actual applications, and the difficulty of processing height of this bistrique, it is also quite high to make use cost.

In sum, prior art can't solve the grinding performance of raising bistrique and the problem of Grinding Machining Quality simultaneously, and this bistrique exactly is the grinding process wilderness demand.

Summary of the invention

The purpose of this utility model is to overcome the shortcoming of prior art and a kind of grinding performance height is provided, and manufacturing is simple and cost is low, the high grinding tool that also can be applicable to extensive grinding of Grinding Machining Quality.

The purpose of this utility model is achieved in that

The utility model comprises matrix and several mill bodies, wherein is fixed in the matrix several mill body spaces, and the mill body also is the gap setting on the grinding face of bistrique;

Wherein, matrix is preferably made by the adhesives with certain toughness, and such as resin, the mill body is preferably made by the diamond alloy material.This is because resin has certain toughness, and adhesive property is good; The grinding performance of diamond alloy material is good, and the conjugation of these two kinds of materials is also higher, can form structural form closely;

In addition, in order to adapt to the grinding requirement of different machined objects, the mill body can be strip, granular or irregular on grinding face;

Best scheme is that the mill body is the uniform gap distribution on grinding face.

Can form the grinding tool that various device needs after the utility model and connector combine, its preparation method is also very simple, can adopt casting or pressing.Wherein the step of casting is: the mill body of required form is positioned in the shaping box, load onto connector, add the colloidal liquid resin, make it to fuse with connector, treat the demoulding behind the resin solidification, to grind body at last and put the first edge on a knife or a pair of scissors and get final product, the method for this manufacturing grinding tool mainly is applicable to strip or block mill body; Pressing mainly is applicable to granular or irregular mill body, after the steps include: the mill body of required form and powdered resin mixed by a certain percentage, is incorporated with in the shaping box of connector, and extrusion forming, heating cure will be ground body then and be put the first edge on a knife or a pair of scissors and get final product.

The utility model has following advantage than prior art:

The utility model is because adopted the diamond alloy material to make the mill body, and the mill body on the grinding face of bistrique is designed to be the gap to be provided with, not only made full use of the grinding performance of diamond alloy excellence, and in grinding process, also reduced the contact area of unit mill body and machined object, increased the pressure of contact-making surface, thereby increased the grinding force of diamond alloy mill body, simultaneously, also increased the quantity of diamond alloy mill body cutting edge, further improved the grinding efficiency of Buddha's warrior attendant stone mill body, its grinding combination property is greatly improved; In addition, adopt toughness material to make matrix, slowed down, protected the integrality of machined object effectively, improved Grinding Machining Quality greatly in the impulsive force that machined object is added man-hour; Also have, this bistrique can be made various grinding tools, the preparation method is simple, and cost is lower, and its service life, more traditional grinding tool was longer, had reduced the number of times of changing grinding tool, had saved material and artificial; Exactly because have above-mentioned various advantage, obvious this bistrique goes for extensive grinding.

The specific embodiment

Embodiment 1: see figures.1.and.2, this bistrique comprises epoxy resin-base 1 and four diamond strip alloy mill bodies 2, wherein four diamond alloy mill bodies 2 are fixed in the epoxy resin-base 1 with gap, and the diamond alloy mill body 2 on the bistrique grinding face also is the uniform gap setting.This bistrique adopts casting to make T type grinding tool, can be contained on homemade 32 continuous polishers, process ceramic polished floor tile, equipment operates steadily, the workpiece not damaged, compare with traditional carborundum grinding tool, grinding force obviously strengthens, and prolongs 80 times service time, the device head number can be reduced to 25 from 32 in the process, can reach the grinding-polishing requirement of traditional carborundum grinding tool equally, the waste material that no bistrique autophage produces in the use, non-environmental-pollution.

Embodiment 2: with reference to Fig. 3 and Fig. 4, this bistrique comprises phenolic resin as matrix resin 1 and a plurality of granular gold hard rock alloy mill body 2, wherein diamond alloy mill body 2 is fixed in the phenolic resin as matrix resin 1 with gap, and the diamond alloy mill body 2 on the bistrique grinding face is the gap and is provided with.This bistrique adopts pressing to make the triangular form grinding tool, and it is installed on the hand steered polishing machine, mainly is applicable to the grinding of granite, marble material.
