Reasons for the high resistance of diamond soft grinding discs:

Roughness of water mill:

The cutting ability of 50-1000 mesh segment is strong, while the cutting ability of 2000# segment drops sharply, and the filling effect is greatly improved. But from 1000# to 2000#, the fineness jumped directly from 13 microns to 6.5 microns. This is actually grinding rough things directly to a very smooth level. To use an analogy, it is equivalent to letting you go up and use a polishing pad to directly smooth out rough surfaces such as lychee noodles and burnt noodles. The resistance is of course great. Moreover, the doubling of roughness creates a kind of peaks and troughs at the microscopic level. There will be gaps between the ground polished by 1000# abrasive disc and the ground polished by 2000# abrasive, forming a kind of sucker effect. Form a strong resistance.

Relation of resin demoulding parameters:

Resin demolding parameters are mainly the relationship between temperature, speed and pressure. In order to cope with such resistance, 2000# grinding discs are needed to effectively complete the release and filling of the resin. Resin demoulding requires a certain temperature, and the low temperature efficiency is very low. The presence of a large amount of water will reduce the grinding temperature, so less water must be discharged during the polishing stage of 1000#, 2000#, and 3000#. High speed is beneficial to increase the grinding temperature. The light weight of the machine helps reduce resistance.

Methods to solve the resistance of diamond grinding discs:

The above two factors are the reasons for the resistance of the diamond water grinding plate. Pay attention to these two factors, the resin can be released and filled by the machine-driven grinding plate. The fineness of the grinding is equivalent to the fineness of the abrasive of the grinding sheet. The resistance is greatly reduced.

Reduce the weight of the machine:

For single-disc machines and grinders with counterweights, the counterweight can be unloaded when grinding 1000#, 2000#, and 3000#. And if necessary, you can manually sprinkle water instead of adding water to the water tank of the machine, which can also reduce weight.

Less water during polishing:

When entering the polishing stage, that is, 1000#, 2000#, 3000#, you must remember to put less water, keep a thin layer of water on the ground, and do not water a lot. Even dry milling can be used.

Growth rate:

For single-disc machines and grinders with variable frequency speed control, if the resistance increases when grinding 1000#, 2000#, 3000#, please refer to the above two items to increase the machine speed. These methods can not only solve the high resistance problem of 2000#, but also the gloss is better than ordinary workmanship.
