Grinding is a common process for hardware mold accessories after long-term use. The abrasive particles embedded in the lapping tool will finish the surface of the workpiece during the grinding process. During the relative movement between the lapping tool and the workpiece, the rust and damage on the surface of the hardware mold accessories will be gradually smoothed and become more smooth. After the grinding process, the hardware mold accessories will have a longer service life and a more significant processing effect. What should we pay attention to when grinding high-quality hardware mold accessories?
1、 Pay attention to the use order of abrasive
Even high-quality hardware mold accessories need to use abrasive in a certain order when grinding, which must be from large particles to small particles, from coarse abrasive to fine abrasive. And in order to avoid the phenomenon of "relief".
2、 Pay attention to the correct use of abrasive
What are the precautions when grinding hardware mold accessories?
In order to avoid scratches on the surface of the hardware mold accessories, only abrasives with the same grain size can be used in the same grinding tool, and the surface of the hardware mold accessories must be carefully cleaned before changing the grain size each time, so as to avoid the residual abrasive with large grain size damaging the accessories in the next process.
3、 Pay attention to the correct operation of grinding with different grain sizes
When an efficient and professional hardware mold parts grinder grinds precision mold parts, when switching to the next particle size grinding process, the grinding direction will be about 30 degrees from the previous grinding direction, because it is not easy to have scars. If there are scars during the switching operation, they should be completely trimmed to remove the pits.
