We need to prepare different standard samples for the mechanical performance testing of polymer materials, which requires a standardized cutting knife.
Proper use and maintenance can make the use of cutting knife long.
Take the rubber dumbbell national standard no. 1 for example, the first step is to heat the high carbon steel first, then the second step is to cut the blank
The knife edge is carefully polished to form a thick and sharp knife with a sharp edge.
Usage and daily maintenance:
Before cutting, pad a macromolecule material board at the bottom of the sample, it is best to smooth the surface of the nylon board, in order to prevent the stamping cutter blade in the process of the impact to the steel workbench lead to edge damage.
2. Regularly apply anti-rust oil to the blade regularly
3. The cutter is heat treatment high carbon steel, hard but afraid to fall.When using the tool, gently hold the cutter, careful not to slip off.
