Description
Technical Field
The invention relates to the technical field of abrasives, in particular to a self-sharpening agglomerated abrasive.
Background
Machining is a main component part of equipment manufacturing industry and is embodied in the national comprehensive national force level. Along with the continuous improvement of the scientific and technical level, particularly the high-speed development of material science, engineering material categories are continuously refined and deepened. Industry chains of considerable size and length have been developed. Compared with a huge number of engineering material systems, the development of the processing materials has the phenomenon of relative hysteresis. As "industrial teeth", grinding is a basic machining method in machining, and has an irreplaceable position. Also, grinding processes are also subject to process mismatch between the abrasive material and the engineered material. In the field of abrasive article manufacturing, the abrasive article manufacturing technology is at its heart. Therefore, development of a novel abrasive is necessary.
In grinding, the abrasive directly participates in the processing of the processed part. In the case of single abrasive particles, the working condition is very bad, and both high grinding heat and heavy grinding load directly act on the abrasive particles. This places higher demands on the properties of the abrasive particles themselves. The high grinding heat not only brings thermal shock to the grinding material, but also affects the processing surface, and the excessive grinding heat can generate burn on the processing surface and has great influence on the surface integrity of the workpiece. The grinding heat is generated partly by cutting away the workpiece material with individual abrasive grains, and partly by the reduced sharpness of the abrasive grains, which is rubbed against the workpiece surface. The frictional heat caused by the reduced sharpness of the abrasive grains should be eliminated as much as possible. Therefore, when the sharpness of the abrasive is reduced, the dull abrasive can timely fall off, and the generation of friction heat can be effectively reduced. Therefore, the abrasive should possess a degree of self-sharpening.
The existing agglomerated abrasive in the market at present is generally aggregated by small particles to obtain large cutting force, high self-sharpening property and continuous grinding force, and mainly comprises the steps of mixing a metal oxide glass binder and fine-grained diamond abrasive, granulating, sintering at high temperature, crushing and grading. The method can obtain isotropic agglomerated abrasive grains, and has consistent cutting edges of the inner layer and the outer layer of the grains and relatively long service life, but the strength of the glass binder is limited, so that the integral strength of the agglomerated abrasive is still not very high, and meanwhile, the technical problem of poor self-sharpening is also solved.
