Grinding is a process that mold parts often undergo after long-term use.

The abrasive particles embedded on the grinding tool will perform fine finishing on the surface of the workpiece during the grinding process. During the relative movement between the grinding tool and the workpiece, the rust and damaged areas on the surface of the mold parts will be gradually ground flat, making it smoother.

Mold parts that have undergone grinding processes will have a longer service life and more significant processing effects. So, what are the matters needing attention during grinding?

1. Pay attention to the sequence of using grinding abrasives

When grinding, it is also necessary to use grinding abrasives in a certain sequence, from large particles to small particles, and from coarse abrasives to fine abrasives. And to avoid the occurrence of the "relief" phenomenon.

2. Pay attention to the correct use of abrasive materials

To prevent scratches on the surface of mold accessories, only the same particle size of abrasive can be used in the same grinding tool. Before each particle size change, the surface needs to be carefully cleaned to avoid the remaining large-particle abrasive from damaging the accessories in the next process.

3. Pay attention to the correct operation of grinding for different particle sizes

When professional mold accessory grinders are grinding precision mold accessories, when switching to the next particle size grinding process, the grinding direction will form an Angle of approximately thirty degrees with the previous grinding direction, because this is less likely to cause scratches. If any scratches occur during the conversion operation, they should be repaired and the pits removed.
