The Importance of Metallographic Cutting Fluid
2020-10-30

  Cutting is the first step in the metallographic sample preparation process. The quality of cutting directly determines whether the entire sample preparation process is 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. The cutting disc rotates at high speed, causing the hard abrasive particles protruding on the surface to impact the sample, and achieves micro-bending and fracture of the target sample in the form of self-loss. Therefore, a large amount of heat will be generated during the cutting process. In addition, the cutting position is concentrated. If the heat is not taken away in time, the temperature at the sample slit will rise sharply, which will cause the micro-structure of the material to change and mislead the analysis results.

 

We usually use concentrated spraying of cutting coolant to dissipate heat and cool down. High-quality coolant should have the following conditions:

1. Large specific heat capacity, more heat can be absorbed per unit volume and unit temperature rise, that is, good cooling effect.

2. It has a certain lubricating effect, reduces the friction between the cutting disc and the sample, and thus reduces heat release.

3. Good wettability, low viscosity, less foam, does not affect observation, and can quickly dissipate after cutting.

4. Antibacterial and mildew-resistant, suitable for repeated use for a long time.

 

It is not easy to find a cutting coolant that meets all the above conditions. Shanghai Truer Company has ingeniously formulated a special coolant suitable for metallographic cutting based on the special requirements of metallographic cutting conditions, which is deeply favored by picky customers.
