Problems solved by technology

The key to recovering the electroplated diamond grinding wheel is to separate the abrasive layer from the matrix, but the separation of the matrix and the abrasive layer in the current structure of the diamond grinding wheel is difficult, and if it is forcibly dismantled, the matrix will be easily damaged, affecting the recovery of the matrix. manufacture

Embodiment 1

[0023] Embodiment one: as shown in the figure, a kind of manufacturing method of electroplated diamond grinding wheel that is easy to recover comprises the following specific steps:

[0024] (1) Take a disc-shaped auxiliary base 2 and two bases 3, process the central shaft hole 31 on the base 3, process the mounting holes 21 on the two ends of the auxiliary base 2, and in the center of the auxiliary base 2 Machining the center hole 22, and controlling the difference between the diameter of the installation hole 21 and the diameter of the center hole 22 to be 10% of the outer diameter of the auxiliary base 2;

[0025] (2) Cut an annular slider 4 on the auxiliary base 2, form an annular fracture 23 on the auxiliary base 2, and make the outer arc length of the slider 4 smaller than the inner arc length;

[0026] (3) Assemble the slider 4 at the annular fracture 23 of the auxiliary base 2, and push the slider 4 outward along the radial direction of the auxiliary base 2 to eliminat...

Embodiment 2

[0030] Embodiment 2: As shown in the figure, other steps are the same as Embodiment 1, the difference is that there is one base body 3, and a stepped through hole 24 is processed on the auxiliary base body 2 in step (1), and the step through hole 24 is controlled. The difference between the large and small apertures is 15% of the outer diameter of the auxiliary base 2 , the shape of the base 3 matches the shape of the stepped through hole 24 , and the base 3 is assembled in the stepped through hole 24 .

[0031] In the above-mentioned embodiment, the ratio of the difference between the diameter of the mounting hole 21 and the diameter of the central hole 22 to the outer diameter of the auxiliary base 2 can be selected in the range of 5% to 30% according to the actual processing needs. The ratio of the difference to the outer diameter of the auxiliary base 2 can be selected in the range of 5% to 30% according to actual processing needs.

Abstract

The invention discloses a method for manufacturing an electroplated diamond grinding wheel capable of being recycled easily. The method has the advantages that during machining, a slider is cut off from an auxiliary base at first, and then is assembled on the auxiliary base, an outer arc surface of the slider and an outer circular surface of the auxiliary base jointly form a smooth electroplating surface, and then a grinding material layer is electroplated on the electroplating surface; when the electroplated diamond grinding wheel is recycled, bases are detached at first, the slider is pushed and pressed so as to be separated from the grinding material layer, and then two opposite acting forces are exerted to two ends of an annular notch of the auxiliary base; the auxiliary base which is thin and narrow can elastically deform to a certain degree under effects of the acting forces, the diameter of the grinding material layer electroplated on the surface of the auxiliary base is not changed, accordingly, a tiny gap can be formed between the grinding material layer and the auxiliary base, and the grinding material layer can be easily stripped off from the auxiliary base; and the bases, the auxiliary base and the slider can be directly reused after the electroplated diamond grinding wheel is recycled.

Description

technical field [0001] The invention relates to a grinding wheel, in particular to a method for manufacturing an easily recyclable electroplated diamond grinding wheel. Background technique [0002] Electroplated diamond grinding wheels are mainly used for grinding the inner shape of hard and brittle materials such as cemented carbide, glass, ceramics, etc. when they are made into products. The electroplated diamond grinding wheel mainly includes two parts: the substrate and the abrasive layer, and the abrasive layer contains diamond abrasive grains. When the abrasive layer is ground many times, the electroplated diamond grinding wheel with diamond abrasive grains remaining loses its grinding ability and is declared scrapped. Diamond abrasive grains are expensive, and the remanufacturing of the substrate also consumes materials and costs, so it is very necessary to remanufacture the scrapped electroplated diamond grinding wheels. The key to recovering the electroplated dia...
