Cutting is the first step in the metallographic sample preparation process. The quality of cutting directly determines whether the entire sample preparation process can be successful, so it is very critical.

Cutting is to cut the original sample to obtain the most representative target analysis surface. Cutting is essentially the process of removing the slit material, and this material removal process is completed by the cutting blade. The cutting blade rotates at high speed, so that the hard abrasive particles protruding on the surface impact the sample, and the target sample is cut in the form of self-loss.

A small saw blade contains a lot of knowledge. First of all, let’s talk about the process steps of the saw blade:

1. Mix the abrasive particles with the molding resin powder.

2. Spread the mixed powder evenly into the mold cavity.

3. Hot press the powder and remove it from the mold after the resin is cured.

High-quality cutting blades will make the cutting process feel light, the cutting surface is even and smooth, and at the same time, the saw blade life is longer. It is not easy to balance these three points. According to the special requirements of metallographic cutting conditions, Truer Company carefully selects superior abrasive particles, optimizes the particle size distribution of abrasive particles, uses high-binding resin powder, repeatedly optimizes the molding process parameters, and develops special saw blades suitable for metallographic cutting.

How to choose the type of cutting blade? Generally, it is selected based on the hardness of the sample material:
