When milling narrow and shallow grooves, if you do not have a suitable milling cutter, you can find a triangular carbide blade into a small milling cutter

Find the thickness of the triangle carbide car blade and measure its thickness. When it is too thick, grind it to the size with a grinder. According to the size of the center hole of the blade, a milling cutter rod is manufactured, and after the cutter blade is mounted on the milling cutter rod, the nut is fastened with a small nut. Since the center hole of the triangular hard alloy car blade has no keyway, the key cannot transmit force, and the fastening force of the small nut is too small, so the car blade should be welded to the milling cutter bar by the brazing method. After the workpiece is clamped on the fixture and milled, it can be milled. Because of this cutter is a negative rake angle. Milling depth, feedrate, and milling speed cannot be large, and the coolant is added to cool.
Back to determine the amount of knife

The amount of back knife is determined according to the stiffness of the machine tool, workpiece and tool. Under the condition of permissible rigidity, the amount of the back tool should be equal to the machining allowance of the workpiece. This can reduce the number of passes and increase the production efficiency. In order to ensure the quality of the processing surface, can leave a small amount of finishing allowance, generally 0.2 – 0.5mm.
Natural single crystal diamond

Natural single crystal diamond is the most wear resistant material in diamond. It is finely grounded and finely ground. The radius of the blunt edge of the cutting edge can be as small as 0.008 to 0.005 μm. However, natural single crystal diamond is brittle, its crystal anisotropy, crystal hardness of different crystal faces or the same crystal face in different directions are all different, and must be selected in the appropriate direction when sharpening and using. Because of the harsh conditions of use, natural monocrystalline diamond resources are limited, and the price is very expensive, so PCD, PCD/CC and CVD diamond tools are mostly used in production.
