What you want to ask is what to do if the trapezoidal thread cutter is not durable? The steps are as follows.

1, reasonable selection of cutting parameters. Adjust cutting speed, feed rate, cutting depth and other parameters to reduce tool wear speed.

2. Improve the cooling effect of the cutter. Use coolant or coolant spray to reduce the working temperature of tools, thus reducing wear.

3. Grind tools regularly. Regular grinding of tools can keep the sharpness and accuracy of tools, thus improving their durability.
