In narrow and shallow groove milling, if not suitable milling cutter, can find a triangular carbide turning blade into a small cutter.

Find the carbide car after measuring the thickness of the triangle carbide, too thick, with a grinding machine to the size of thin. According to the size of the center hole of a blade car milling cutter bar, the car blade mounted to the cutter bar with a small nut fastening. Because the triangle carbide car blade center hole no keyway, can not use the key transmission force, and the small nut clamping force is too small, so should use the brazing method to welding the blade to the cutter bar. The workpiece can be milled after it is mounted on the fixture and the knife is good. Because of this cutter negative angle. Milling depth, feed rate and milling speed can not be large, and filling coolant cooling.
