Therefore, the clamping process takes a long time and is difficult. Especially when processing large molds with more complex inclined guide post holes and higher precision requirements, the bevel cutting accuracy is not easy to control and the mold is not easy to fix. If you are not careful, the mold will be scrapped, so a special fixture is needed.
