Problems solved by technology

The shape of the currently used cutter head is an approximate cuboid, distributed vertically along the radial direction of the mounting substrate. This structural setting is mainly for the convenience of cutter head processing and installation, but it will have a great impact on the performance of the diamond grinding wheel, because the installation The substrate is ring-shaped, and the cutter heads are arranged on the edge of the mounting substrate in a circular shape, so that when the radial width of the cutter heads along the mounting substrate is equal, (1) The distance between adjacent cutter heads is from outside to inside Gradually shrinking, if the arrangement is not careful when welding and fixing, adhesion will occur. The distance between the cutter heads is to remove chips and take away heat. The diamond grinding wheel provided by the prior art is along the diameter of the mounting substrate because the distance between adjacent cutter Gradually shrinking in the direction, or even sticking, which will cause poor chip removal during grinding, affecting the polishing effect and the service life of the diamond grinding wheel; Poor degree, low grinding efficiency

specific Embodiment 1

[0027] In this embodiment, a diamond grinding wheel is provided, which includes a ring-shaped mounting substrate 1 and a plurality of diamond bits 2 fixed on the edge of its upper surface. The diamond bits 2 are arranged in a ring shape, adjacent to each other. There is a gap 4 between the diamond segments 2: the diamond segments 2 are distributed along the radial direction of the mounting substrate 1 at an angle of 30°, and the distance between the diamond segment 2 and the center of the mounting substrate 1 has a basis From the width of gradual change, when being the width of gradual change, the farther away from the center of the grinding wheel, the wider the width, the outside of the diamond cutter head 2 is arc-shaped and the radius of the arc is the same as that of the mounting substrate 1 The radius difference is less than or equal to 5 mm; a mounting hole 3 is provided in the center of the mounting substrate 1 , and positioning holes 10 are also provided around the moun...

Embodiment 2

[0033] In this implementation, it is basically the same as Embodiment 1, the difference is that the diamond cutter head 2 has an equal width from the center of the mounting substrate 1, so that the specifications of each diamond cutter head are consistent, and when in use The amount of grinding is also consistent, avoiding the reduction of life due to severe wear of a certain part.

[0034] Moreover, in this embodiment, the radius of the outer arc surface of the cutter head is equal to the radius of the mounting substrate.

Embodiment 3

[0036] In this embodiment, in order to make the diamond grinding wheel have a better use effect, it is specially improved. Specifically, improve the diamond cutter head 2 on the grinding wheel, as attached Image 6 , 7 , 8, the diamond cutter head 2 is provided with acute-angle helical teeth inclined toward one side at least on the inner side of the mounting substrate 1 along the radial direction. In this way, during the grinding process, when the rotation direction of the diamond grinding wheel is consistent with the direction of the sharp helical teeth, the sharp helical teeth first contact with the workpiece, which can cut quickly, thereby improving the cutting efficiency. Refer to attached figure 1 At present, the traditional diamond grinding wheel adopts the structure of the cutter head as a flat tooth. When the structure of this flat tooth is used for grinding, most of the side of the cutter head is in contact with the workpiece, and the grinding effect is poor and the...

Abstract

The invention relates to a diamond grinding wheel which comprises an annular mounting baseplate and multiple diamond tool bits fixed at the edge of the upper surface of the annular mounting baseplate. The diamond tool bits are arranged in the shape of a circular ring, a gap is formed between each two adjacent diamond tool bits, the diamond tool bits are distributed in a manner of radially inclining along the mounting baseplate, and distances between the diamond tool bits and the center of the mounting baseplate are equal or gradually change; when width gradually changes, the longer distance with the center of the grinding wheel is, the large width is; the outer side of each diamond tool bit is in the shape of an arc, and difference between radium of each arc and that of the mounting baseplate is smaller than or equal to 5mm. Compared with the prior art, the diamond grinding wheel has the advantages of good heat-radiating performance, long service life and convenience for production and machining.

Description

technical field [0001] The invention relates to a grinding tool, in particular to a diamond grinding wheel for grinding hard materials. Background technique [0002] Most ceramic tiles or stones require fixed length and width specifications for ease of construction and installation, so edge grinding is required. Grinding the edges of ceramic tiles or stone requires the use of specific abrasives - diamond grinding wheels. The grinding tool of the diamond grinding wheel grinds the product to obtain a product with a fixed specification. Specifically, the diamond grinding wheel is vertically installed on the driving device, and the driving device drives it to rotate at a high speed. When the workpiece to be processed passes through it, the diamond grinding wheel grinds the edge of the workpiece, so that the workpiece obtains a fixed length and width. Specification. Of course, this processing is not limited to ceramic tiles or stone, most hard materials can be processed. [0...
