As a tool that is often used in industrial production, ultra-thin resin cutting disc play a very important role. In order to be able to complete the work well, first of all, we need to pay special attention when purchasing. The following editor will tell you in detail how to distinguish the quality of ultra-thin resin cutting grinding wheels, let’s take a look together.

1. Check the nameplate and manual of the stone cutting machine, the parameters should be consistent with those on the certificate.
2. Observe the outer packaging of the stone cutting machine. The outer packaging should have clear patterns and no damage. Open the box to observe the appearance of the stone cutting machine, the color should be uniform. There should be no obvious shadows and dents on the surface of plastic parts, and there should be no scratches or bumps. The coating of aluminum castings is smooth and beautiful without defects, and the surface of the whole machine should be free of oil stains and stains.
3. Hold the stone cutting machine by hand, turn on the power supply, and frequently operate the switch by hand to make the tool start frequently. Observe whether the on-off function of the switch of the stone cutting machine is reliable.
4. During the trial operation of the cutting disc. At the same time, observe whether there are any abnormal phenomena in the TV and fluorescent lamps on site. in order to confirm whether the tool is equipped with a radio interference suppressor.
5. Observe the reversing spark during trial operation, and the reversing spark should not exceed 3/2 level. Generally looking in from the air inlet of the tool, there should be no obvious arc on the surface of the commutator. During operation, there should be no abnormal noise.

The reason for the ultra-thin resin cutting disc film.

1. When the hardening temperature is low or too high, the temperature and humidity suddenly change drastically. In addition, the fluctuation of relevant technical indicators of the raw materials at the same time meets the conditions required by Huaji to cut the grinding wheel film. At this time, if the hardening curve is still the same as before, the film came into being.
2. The time of hardening curve is short. This mainly means that under certain conditions, the low-temperature drying time of the hardening curve is short, and the heating rate in the heating stage is too fast.
3. The furnace or the kiln is too fast or the temperature difference is too large. Because the grinding wheel is especially the grinding wheel with large diameter. There should be a cooling time period at the end of the hardening and soaking period to meet the uniform stress relief of the resin cutting wheel. At this time, if the furnace temperature is too high or the temperature difference changes too much. The cooling change of the grinding wheel will not be synchronized, so the deformation of the grinding wheel will appear. Resin grinding wheel cutting sheet film is actually a form of deformation.
