Fast 9'' grinding wheel - online electrolysis sharpening principle

The principle of online electrolysis and sharpening super abrasive fast 9'' grinding wheel. At the beginning of the electrolysis sharpening, the binder portion of the cast iron bonder grinding wheel will be electrolyzed due to the action of the electrolyte to generate iron ions. Iron ions form a product such as iron hydroxide and iron oxide in the grinding fluid due to chemical action.

The iron hydroxide is easily dehydrated to form an iron oxide, and this newly formed substance is deposited on the surface of the fast 9'' grinding wheel, and an oxide film having an insulating property is gradually formed. The presence of the film causes the electrolysis current acting on the binder to gradually decrease. This is the initial trimming.

As the grinding process progresses, the top surface of the fast 9'' grinding wheel wears gradually wear. At this time, the friction and extrusion of the grinding debris and the surface of the workpiece will gradually peel off the oxide film of the original abrasive grain, and the conductivity of the fast 9'' grinding wheel begins to recover again. The electrolysis process on the surface of the grinding wheel is started, and the grinding wheel is continuously trimmed by in-line electrolysis to obtain a constant protrusion height of the abrasive grains, and the dynamic balance of the insulation layer generated by the surface oxide of the fast 9'' grinding wheel is used to realize the most adaptive control. Good grinding process.

Grinding Temperature Of Different Grinding Wheel

The types of fast grinding wheel for stainless steels are different, and the cutting properties, anti-adhesive wear resistance and thermophysical properties of the abrasive grains are very different. Therefore, when different types of the fast grinding wheel for stainless steels grind ultra-high-strength steel, the grinding temperature is different.

When the single crystal corundum and white corundum fast grinding wheel for stainless steel grind 300M steel, the grinding temperature is not much different, and the grinding temperature of CBN grinding wheel is much lower than the grinding temperature of corundum grinding wheel. Although the grinding speed of CBN grinding wheel is almost twice that of white corundum fast grinding wheel for stainless steel, the grinding temperature of CBN grinding wheel is about 250 °C lower, which is due to the anti-adhesion and wear resistance of the abrasive grain during the grinding process. It can maintain a sharp cutting edge, has a strong cutting ability, is smaller than grinding energy, and has less friction between the abrasive grains and the workpiece surface, resulting in less grinding heat.

In addition, the fast grinding wheel for stainless steel has strong thermal conductivity, and its thermal conductivity is as high as 1300W/(m·K), while the thermal conductivity of corundum abrasive is only 36W/(m·K). The thermal conductivity of low carbon alloy steel is Between 40-60 W/(m·K), the heat in the grinding zone is more transmitted by the CBN abrasive particles.

How to choose the grinding wheel in the sharpening process?

Fast 9'' grinding wheel is widely used in the machining industry. Because machining requires the use of turning tools, but the turning tools need to be sharpened, what kind of requirements does the turning of the turning tools have on the grinding wheel? How to choose the grinding wheel? Let us listen to the grinding wheel production. How do manufacturers say it?

Whether the fast 9'' grinding wheel looks at the abrasive, the second looks at the particle size, and the third depends on the hardness.

Commonly used abrasives are oxide series, carbide series, and high hard abrasive series. Alumina fast 9'' grinding wheel has a slightly lower hardness, but it has high toughness. It is suitable for sharpening high-speed steel turning tools. The white one is called white corundum and the taupe is called brown corundum. The particle size indicates the extent of the size of the abrasive particles, with the number of holes per minute through which the abrasive particles can be represented. The larger the number, the finer the abrasive grain. For rough grinding tools, choose a grinding wheel with a small number of grits.

The hardness of the fast 9'' grinding wheel reflects the difficulty of the abrasive particles falling off the surface of the grinding wheel under the action of the grinding force. The grinding wheel is hard, that is, the surface abrasive grains are hard to fall off; the grinding wheel is soft, indicating that the abrasive grains are easy to fall off. The hardness of the grinding wheel and the hardness of the abrasive grains are two different concepts that must be clearly distinguished.

The choice of the fast 9'' grinding wheel should be determined for the sharpening object. Different grinding wheels are suitable for different sharpening objects, so it should be determined according to the actual situation in practical applications.

How to maintain the fast cheap metal grinding disc

1. The fast cheap metal grinding disc has weak bonding strength, so the self-sharpening property during grinding can be good, it is not easy to block, the grinding efficiency is high, the grinding force is low, the grinding temperature is low, and the disadvantage is that the wear resistance is poor and the wearer wears out. Large, not suitable for heavy duty grinding.

2. Fast cheap metal grinding disc wear resistance and bonding ability is better than resin binder, cutting sharp, high grinding efficiency, not easy to heat and block, less thermal expansion, easy control accuracy, disadvantages grinding surface is thicker, higher cost.

3. Fast cheap metal grinding disc has high bonding strength, good wear resistance, low wear, long service life, low grinding cost, and high load, but poor sharpness and easy blockage.

4. Abrasive grain size has a certain influence on the clogging and cutting amount of the grinding disc. Compared with the fine sand grain, the coarse sanding grain has a larger wear depth of the cutting edge, and the fast cheap metal grinding disc is easy to block.

5. The hardness of the grinding disc has a great influence on the blockage. The high hardness of the grinding disc is high, which is not conducive to the surface heat dissipation, which is beneficial to improve the processing precision and durability.

6. The selection of the fast cheap metal grinding disc concentration is an important characteristic. It has a great influence on the grinding efficiency and the processing cost. If the concentration is too low, the efficiency is affected. On the contrary, the abrasive grains of the fast cheap metal grinding disc are easy to fall off, but the concentration range of the good bonding agent is also good.

China grinding wheel supplier talks about grinding wheel

China grinding wheel supplier talks about the classification and use of grinding wheels. I don’t know how much you know about the grinding wheel. Most of the grinding wheels are made of fiber and resin as a reinforcing bonding material. High tensile, impact and flexural strength.

Use of grinding wheel
Nowadays, the grinding wheel has been widely used in the production of ordinary steel, stainless steel and non-metal. With more and more machinery industry, more mechanical products need to be processed. Usually, the first step of each product needs to pass the grinding wheel. Cutting and forming, and then carrying out subsequent grinding and polishing. So, what is the classification of the grinding wheel? Following China grinding wheel supplier and manufacturer comes to tell you.

According to the materials used, the grinding wheel can be divided into resin grinding wheel, stainless steel grinding wheel, diamond grinding wheel, etc. It is believed that many suppliers know that the grinding wheel and cutting piece belong to the grinding wheel, and we are specialized in producing all kinds of grinding wheel cutting piece.
