Description

technical field [0001] The invention belongs to the technical field of grinding wheel production and manufacturing, and in particular relates to a device and method for adhering an abrasive block of a superhard material grinding wheel and a substrate. Background technique [0002] Due to the advantages of high strength, long service life and high processing precision, superhard material grinding wheels, as the preferred tool, play an irreplaceable role in the field of processing difficult-to-machine materials. Superhard material grinding wheels are usually composed of grinding wheel substrates, abrasive layers and bonding layers. In the preparation process of superhard material grinding wheels (especially large-diameter grinding wheels), it is difficult to realize the integral abrasive layer preparation process. Usually, the abrasive layer is made into A number of abrasive blocks are subsequently spliced ​​into an overall abrasive layer by bonding, and then consolidated on t...

AI Technical Summary

Problems solved by technology

[0005] (1) The adhesive layer is difficult to control. Due to manual application of the adhesive, it is difficult to guarantee the uniformity of the adhesive on the grinding wheel base and the grinding wheel block;

[0006] (2) The pressing force of the grinding wheel block is inconsistent, especially during the curing process of the adhesive, the pressing force is constantly changing, resulting in different bonding strengths between the abrasive block and the substrate;

[0007] (3) Low efficiency, since each abrasive block must be pressed by bolts, the operation is cumbersome and the production efficiency is low;

[0008] (4) The curing strength between the abrasive block and the grinding wheel substrate is different. Due to the uneven temperature field in the oven, the curing speed of the adhesive layer is not equal, resulting in a large bonding stress between the abrasive block and the substrate;

[0009] (5) The waste of energy is serious, because during the curing process of the adhesive, the grinding wheel base and bonding related parts are all in the oven, the temperature rises slowly, and the energy is not effectively used
