Abstract

The utility model relates to a grinding tool, in particular to a new type of grinding wheel for ceramic walls and floor tiles. Existing grinding wheels are composed of a basal body and a grinding body containing diamonds, wherein the grinding body containing diamonds cannot firmly adhere to the basal body. As a technical proposal, the new type of grinding wheel for ceramic walls and floor tiles comprises a basal body and a grinding body containing diamonds referred to as the grinding body, wherein both the basal body and the grinding body are annular. The utility model is characterized in that: the grinding body is fixed on the basal body through a binding layer that does not contain diamonds. The binding layer without diamonds can firmly bind the basal body and the grinding body without falling. Besides, the proposed grinding tool facilitates chip escape and heat radiation, and edge-breaking and heat stress become rare. The utility model can widely be to various grinding tools, in particular to dry grinder for ceramic walls and floor tiles.

Description

New ceramics wall, floor tile emery wheel

Technical field

The utility model relates to a kind of grinding instrument, particularly a kind of new ceramics wall, floor tile emery wheel.

Background technology

Existing emery wheel comprises matrix, diamantiferous mill body---hereinafter to be referred as the mill body, wherein grinds body and is fixed on the matrix by binder course.The mill body of some emery wheel is a complete annulus, and this emery wheel is difficult for making ceramic tile to collapse the limit in use, but is unfavorable for chip removal and heat radiation, in the use, easily because of the inequality of being heated, and the crack occurs.The mill body of some emery wheel is made up of the abrading block of a plurality of annular spread, helps chip removal and heat radiation, but makes ceramic tile collapse the limit easily.

The utility model content

The technical problems to be solved in the utility model is the above-mentioned defective that how to overcome existing emery wheel, and a kind of new ceramics wall, floor tile emery wheel are provided.

For solving the problems of the technologies described above, this new ceramics wall, floor tile comprise matrix, diamantiferous mill body with emery wheel---hereinafter to be referred as the mill body, the two is annular, wherein grinding body is fixed on the matrix by binder course, it is characterized in that: the outer rim of described mill body or inner edge are provided with the slot area that has a plurality of grooves, and the radical length of this slot area is poor less than the inside and outside radius that grinds body.So design, 1., when the rotation of mill height speed described groove forms a plurality of teeth on the outer rim of mill body or inner edge, make the similar gear structure of whole mill body, and following advantage is arranged:, form cyclone, be the chip removal of mill body, heat radiation by wind-force; 2., be difficult for producing the crack because of thermal stress; 3., the working (machining) efficiency height, be not easy to make work piece to collapse the limit; 4., mechanical strength is big.

As optimization, described groove evenly distributes on mill outer rim of body or inner edge, the center of its extended line by emery wheel or tangent with the concentric circles of emery wheel.So design, stressed even, structural strength is big.

As optimization, the opening of described groove is less, and root is bigger, is trapezoidal; Or opening, root equate, and be rectangular.So design, the spacing between tooth and the tooth is less, and during use, stressed variation is little, and tooth is not vulnerable to impact, and helps to save material.

As optimization, the axial depth of described groove is less than or equal to the axial width that grinds body.So design, the axial depth of described groove is less than the axial width of mill body, and structural strength is big; The axial depth of described groove equals to grind axon to thickness, and chip removal and good heat dissipation effect can adapt to different requirements.

As optimization, also have a through hole in each groove, above-mentioned through hole runs through emery wheel, and its outlet is positioned on the operative end surface of mill body, and its inlet is positioned on the matrix.So design during use, feeds cooling medium in the through hole, can directly enter the operative end surface of mill body, cooling mill body, chip removal in time simultaneously.

After adopting technique scheme, this new ceramics wall, floor tile emery wheel have the chip removal of being easy to and heat radiation, and are difficult for making ceramic tile to collapse the limit, are not prone to the advantage of thermal stress, extensively are suitable for various mill cutting tools, are particularly useful on the dry mill of ceramic wall, floor tile.
