CBN grinding wheel is based on diamond CBN abrasives. It uses metal powder, resin powder, ceramics, and electroplating as a binding agent. The grinding ability is very strong and long.
However, the use process of diamond CBN grinding wheels should pay special attention to some matters, which is different from the Jade Silicon wheel to use the normal use of the Vajrayana CBN wheel and exert its due performance.
1. After the sand wheel is installed with a flange plate, do not completely tighten the screws. You can knock on the substrate part with a wooden stick. Correct the outer round of the sand wheel and beating within 0.03mm, and then tighten the screws. Don't remove it from the flange plate. The best solution is to install flanges.
2. The rigidity of the machine tool is better, and the main axis beating is less than 0.01mm. Try to choose high speed.
3. Due to the small loss of diamond CBN wheels, the rough grinding knife is not greater than 0.03mm, and the fine grinding knife is not greater than 0.01mm. Frequent continuous knife can cause the wheel life to decline sharply. Like the unintentional grind, it is 0.03mm a day, a total of 0.03mm. The most outrageous thing is that a client continuously entered the knife like an ordinary sand wheel, and a diamond sand wheel was used up a day.
4. Due to the high grinding efficiency, the heat generated is also large, so the cooling must be sufficient during grinding. The water pump is larger than when the pump is used to use the jade carbide wheel. The cooling nozzle should be aimed at the grinding site. Monitor the water temperature and cool down in time.
5. As the water temperature rises, the wheels will swell, and the size of the workpiece will be measured in time, and the knife will be retreated in time according to the data to prevent the size from negative. It can be used normally after stability.
6. When the new sand wheel starts to use it, it is found that the concentricity is not good. You can use the silicon carbide wheel to repair or repair it by grinding silicon oil stones. The most economical method is to repair the concentricity by leaving the amount of waste at the same time. During the grinding process, if the wheel is not sharp enough, you can also hold the coil carbide sand oil and stones to carefully renovate the surface of the sand wheel.
7. Before and before booting, one must check whether there are cracks or gaps. Once you find it, install or use it. Avoid standing opposite the sand wheel during use, put the baffle or close the protective door.
