Resin ultra-thin cutting wheel has the advantages of high cutting efficiency, good incision quality, less loss of cut material, etc. It is developed on the basis of common products according to the grinding process requirements, and the cutting speed can reach 60 ~ 100m per second. Resin bond has good plasticity and ductility, suitable for manufacturing various specifications of products. Some customers have higher requirements for the cutting strength of this product, if you feel that the cutting strength is low, Xiaobian will teach you a trick to improve the bond strength.
Based on the analysis of interfacial wetting and bonding, the possibility of improving the grinding performance and grinding tool strength of this product was discussed.
1. Interface infiltration theory
Good infiltration of the filler is extremely important for the liquid resin, poor infiltration will produce a gap on the interface, easy to make the stress concentration and fracture of the material, if completely infiltrated, the bonding strength between the matrix and the filler will be greater than the cohesion strength of the matrix.
2. Interface bonding
In order to obtain a relatively large bonding strength, the adhesive and the bonded abrasive must have affinity, and the two must be in complete contact, so the bonded abrasive must be clean. In order to make the adhesive and the body to be fully in contact.
The wetting state between the adhesive and the bonded body is a prerequisite for good bonding performance of the cemented joint.
Mix according to different mixing processes. According to the same pressing process, the forming material is pressed into a resin ultra-thin cutting wheel and cured under the same curing process conditions.
The gravity of the cutting equipment is used as the radial cutting pressure, so its parameters are relatively stable. The speed of the cutting machine determines the linear speed of the product, that is, the relative speed of the product and the workpiece, which is very important for the cutting efficiency of the product.
The resin ultra-thin cutting wheel made by the above two processes has significantly improved the grinding performance and grinding tool strength than the products made by the traditional process.
