In turning machining, it is often necessary to make the cutting edge of the turning tool slightly lower than the center of rotation of the workpiece or the turning point of the turning tool and the center of rotation of the workpiece. If the tool tip is higher than the center of rotation of the workpiece, the machined part can not meet the accuracy requirements, the part geometry is deformed or the roughness is poor, and the tool is easily damaged.
Wrench: A commonly used installation and disassembly tool.Wrench is a hand tool that uses the principle of a lever to turn the opening or socket of bolts, screws, nuts, and other threaded tightening bolts or nuts.
Wrenches are usually made of carbon or alloy structural steel.
The wrench is usually provided with an opening or sleeve hole for holding the bolt or nut at one end or both ends of the handle. When it is used, external force is applied to the handle along the direction of thread rotation to twist the bolt or nut.
