Grinding is a process which is often carried out after the hardware mould parts are used for a long time. The abrasive particles embedded on the lapping tool will finish the surface of the workpiece in the process of lapping. In the process of the relative movement between the lapping tool and the workpiece, the rust on the surface of the hardware mold accessories will be gradually ground flat and become more smooth. After the grinding process, the service life of the hardware mold parts will become longer, and the processing effect will be more significant. So what should be paid attention to when grinding high-quality hardware mold accessories?

I. pay attention to the use sequence 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 "relief" phenomenon.

II. Pay attention to the correct use of abrasives

In order to avoid scratches on the surface of hardware mold accessories, only abrasive with the same particle size can be used in the same lapping tool, and the surface of hardware mold accessories must be cleaned carefully before changing the particle size every time, so as to avoid the residual abrasive with large particle size damaging the accessories in the next process.

III. pay attention to correct operation of grinding with different particle sizes

When the high-efficiency professional hardware mold accessories grinder grinds the precision mold accessories, when changing the next granularity grinding process, the grinding direction will be about 30 degrees from the last grinding direction, because it is not easy to get scars. If there is any scar in the process of switching operation, it shall be completely repaired to remove the pit.
