What are the characteristics of the grinding process used by high-precision grinding machines

1. The grinding tool has multiple edges and high grinding speed The grinding method adopted by high-precision grinding machine is to use the high-speed rotating grinding wheel as the cutting tool, so as to realize the fine cutting of the workpiece surface. Therefore, most of the abrasive tools used in high-precision grinding machines are multi-edged and have high grinding speed. This is because the grinding wheel surface has a self-sharpening effect, so that the surface of the parts can obtain a high-precision fine surface. 2. There are many kinds of materials suitable for grinding According to the survey feedback data, there are many kinds of materials suitable for grinding by high-precision grinding machines. Because most grinding processes take grinding wheel as the main tool, which is made by bonding abrasive grains and binding particles, so each abrasive grain is equivalent to a cutter tooth, so it can grind both soft and hard materials, and each cutter tooth can reasonably grind the material. 3. It is suitable for cutting extremely thin surfaces and has a high cutting rate The grinding process used by high-precision grinding machine is also particularly suitable for cutting extremely thin surface and has a high cutting rate. Because the abrasive grains on the grinding tools are of different shapes and all are irregularly distributed, the selection of this high-performance grinding machine can ensure that it has strong extrusion and friction polishing while cutting the extremely thin surface, so that it also has a high cutting rate for the extremely thin surface.

Which products are more suitable for grinding with high-precision grinding machine

1. Powerful cutting tool According to relevant survey feedback, a large number of high-precision grinding machines have been widely used to grind various cutting tools. This is because the precision large size complex wheel groove forming powerful cutting tools have very high requirements for grinding accuracy, and the performance parameters of high-precision grinding machines are more in line with the requirements of grinding accuracy, wear resistance and dimensional stability, so they are particularly suitable for machining powerful cutting tools. 2. Plane groove High-precision grinding machine has gradually become one of the indispensable important equipment for grinding plane grooves. Some mechanical components are grinded into a variety of plane grooves with different shapes due to the working conditions and structural technological requirements, which requires that the grinder can accurately control the accurate cutting of different planes. Even if the grinding stress increases rapidly, the grinder can ensure that the mechanical components maintain high accuracy during grinding. 3. R-type milling cutter It is well known that the R-type milling cutter has very high requirements for grinding equipment. The high-precision grinding machine is made of CCr15SiMn, T10, T8 and other materials. When grinding the R-type milling cutter, it only needs to be equipped with pre-treatment such as quenching, tempering and high temperature tempering to make the R-type milling cutter obtain a more fine surface, and at the same time, it can also meet the wear requirements of the parts in the process of use.

How to select high precision grinding wheel

1、 Selection of abrasive The choice of abrasive for high-precision grinding wheel is a kind of knowledge. The choice of abrasive mainly depends on the workpiece material and heat treatment method. When using high-precision grinding machine to grind materials with high tensile strength, we should choose materials with greater toughness; When grinding materials with high hardness, the abrasive with higher hardness should be selected; When grinding materials that are not easy to be processed, the abrasive with chemical reaction should be selected. 2、 Selection of granularity The grain size of the grinding wheel of the high-precision grinding machine mainly refers to the grain size of the abrasive, which mainly depends on the surface roughness and grinding efficiency of the grinding price. The grain size is mainly expressed by the grain size number. When grinding with the coarse-grained grinding wheel, the production efficiency is high, but the grinding surface is relatively rough; When grinding with fine-grained grinding wheel, the surface roughness of the workpiece is good, but the productivity is very low. 3、 Selection of hardness The hardness of the grinding wheel of high-precision grinding machine refers to the difficulty of the abrasive particles falling off under the action of external forces, which mainly depends on the material of the workpiece to be ground, the grinding efficiency and the quality of the machined surface. If the grinding wheel is selected too hard, the grinding particles will not fall off; If the grinding wheel is too soft, it will increase the wear of the grinding wheel, thus losing the correct geometric shape.
