What are the types of car knives?
In addition to what the landlord said, I would say a few more, for I have been doing machine work for ten years. I can only think of such a thing as cutting knives, boring machetes, R knives, and internal grooves. Our company also has numerical control machine, but the knife that used to be on top is oneself grind.
The tool can be divided into outer circle, shoulder, end face, cutting, cutting, thread and forming tool. There are also car knives for automatic line and digital control machine tools. The structure can be divided into the overall car knife, the welding tool, the lathe tool, the turning tool and the shaping tool
According to the structure of the knife: overall knife (usually high speed steel and tool steel material), welding knife (usually carbide or diamond of the cutting tools, welding on 45 # steel knife body or tool rod), and machine clamp knife (usually cemented carbide or hard ceramic cutter, with mechanical force clamped on 45 # blade or other materials), etc. Press the material of knife: high speed steel, tool steel, hard alloy, super hard ceramics (such as cubic nitride boron), diamond etc. Use of knife: external round knife, inner hole knife, cutting knife, cutting knife, thread knife and various molding knife.
