1. Pay attention to the cutting angle (such as rake angle and rake angle, etc.); In order to make each surface of the turning tool look like a surface, the cutting surface of the turning tool must be moved slowly during grinding; In order to facilitate observation, pay attention to keep the cutting edge of the turning tool at the top all the time during grinding.
2. Before uncoiling the chip groove, check the shape of the cylindrical surface and side surface of the grinding wheel, and the R angle here should not be too large (dressing the grinding wheel or replacing it if necessary); When slotting, the point of the knife is upward, so the hand must move up and down in a straight line. You can find a position on the grinder by hand, so that the hand will not shake. At the beginning of slotting, it is necessary to select the moving order of the rear part of the turning tool bit to the bit, and constantly check the condition of the edge.
3. The thread grinding tool should also use the template to avoid the wrong angle.
meaning a turning tool is a tool with a cutting part used for turning. Turning tool is one of the most widely used tools in cutting. The working part of turning tool is the part that produces and processes chips, including the blade, the structure that breaks or rolls the chips, the space for removing or storing chips, the channel of cutting fluid and other structural elements.
Introduction The cutting part of turning tool is composed of main cutting edge, auxiliary cutting edge, rake face, main flank and auxiliary flank, and tool tip angle. The combination of cutting part and handle (clamping part) of turning tool mainly includes integral, welding, mechanical clamping and welding-mechanical clamping. Mechanical clamping lathe tool can avoid the stress and crack of cemented carbide blade during high temperature welding, and the handle can be used many times. Mechanical clamping lathe tool is generally a mechanical clamping lathe tool that clamps the blade with screws and pressure plates and installs the indexable blade. After the blade is blunt, it can be indexed and used continuously, and the time for stopping and changing knives is short, so it has made rapid development.
