Precautions

1. Replacement of passivated sand. When the passivation time of 400# sand tool is more than 20 minutes, the sand needs to be replaced or redeployed.

2. After the replacement of new sand, the passivation time of the first mode tool should be reduced. The passivation time cannot be reached once, but should be gradually extended to the range.

3, for the small number of sample knives, clamping should be separated from the isolation of clamping passivation.

4. The passivation time of the first mode tool at work should be reduced by 3 minutes every day. The passivation time should not be put into place once, and the passivation time should be gradually extended to the range.

    Diamond Frets files for processing guitar frets

    Diamond fret files can easily process hard metals and high-hardness frets with their ultra-high hardness and excellent cutting performance, significantly improving work efficiency. Their excellent wear resistance and low heat generation characteristics ensure that the files remain sharp and the shape of the workpieces remains stable during long-term use. At the same time, the surface of diamond files is not easy to clog, and they are easy to clean and maintain. They are suitable for finishing work that requires high precision and high finish, such as flattening, crowning and polishing of guitar frets. A variety of shapes and specifications make them widely applicable and have unparalleled advantages in various professional and industrial applications.
