A kind of diamond grinding roller and its manufacturing method

Abstract

The invention provides a diamond grinding roller and a manufacturing method of the diamond grinding roller. The diamond grinding roller comprises a basic roller, a grinding bucket and a column type fixed part, wherein the basic roller comprises a connecting part used for being connected with using equipment, the column type fixed part is used for connecting a grinding ring in a sleeved mode, the surface of the fixed part is axially provided with at least one constant hump or one depression, and the grinding bucket is provided with a plurality of superimposed grinding rings. Two ends of the diamond grinding roller are designed into an integrated cutting head, the middle part of the diamond grinding roller is a discontinuous cutting head, so that the relative positions of middle pieces can be arbitrarily placed, and the integrated gap groove is a large helical angle. The radial surface of the cutting head is an arc-shaped surface or a surface with an angle is formed with the radius, the structure is better for chip removal, the cutting blade is broken line shaped of parallel axes, an axial component force cannot occur during working, and the grinding is more stable. The integrated cutting head end pieces are arranged on the two ends, so that the outer working surface of the whole grinding roller has the cutting head contact grinding at any time, and the impact due to the intermittent grinding is prevented.

Description

technical field [0001] The invention belongs to the technical field of mechanical manufacturing, and in particular relates to a diamond grinding roller and a manufacturing method thereof. Background technique [0002] Diamond tool products are a new type of processing tool developed in recent decades. It is widely used in the processing of non-metallic superhard superabrasive materials, and is an indispensable tool and cutting tool for these industries. Diamond tool products are mainly divided into three categories: cutting, drilling and grinding. Among them, diamond grinding roller is the main product in grinding tools. It is widely used in grinding, polishing and finishing of superhard materials such as stone, cement and ceramics at home and abroad. In the process, it has a very important impact on the quality and processing cost of these products. [0003] my country is a major producer of stone, cement products, and ceramic material products. Its products not only suppl...

AI Technical Summary

Problems solved by technology

The disadvantages of this process are: it is difficult to produce diamond grinding wheels with a large helix angle, resulting in low roundness of the grinding rollers, discontinuous grinding, impact, and thus instability. Not only is the operation difficult, but the surface precision of the processed products is low.

Its technology is backward, the production efficiency is low, and it is not easy to realize automation

And waste a lot of precious metal-silver alloy

Even for diamond grinding rollers without helical teeth, due to the uneven density, hardness and strength of the diamond cutter head, the grinding performance varies greatly, which seriously affects the quality of processed products, production costs and efficiency.

at the same time, Figure 8 As shown, the integral cutter head grinding roller grinds smoothly, but the grinding speed is low

Figure 10 The grinding roller with evenly distributed cutter head has high grinding efficiency, but it has impact and poor stability, and there is axial component force during the grinding process, which increases the labor intensity of operation and makes noise, especially at the beginning of the grinding surface. And towards the end, due to the impact of intermittent grinding, the surface quality of the ground surface is reduced

The reason is that the cutter head with a nearly rectangular cross-section evenly distributed on the circumference is discontinuous in the circumferential direction, and it is difficult to make a cutter head with a large helix angle on the axial surface due to the limitation of process manufacturing and cost, so that in the grinding operation some The position does not have the cutter head to participate in the cutting
