What are the safe and correct operating procedures for boring cylinder workers?

Before working, boring machine workers must check whether each system of the machine tool is safe and easy to use, whether the position of the handwheel crank is correct, and whether the fast feed is barrier-free. Limit stop should be installed correctly. Every time you start the car and start the moving parts, pay attention to whether the knife and handle are in the required position and whether the fast moving parts are in the same direction. It is forbidden to start the fast moving handle suddenly. Before starting the machine tool, check whether the boring cutter is firmly fastened, whether the workpiece is firmly clamped, the pressure plate must be stable, and the pad iron supporting the pressure plate should not be too high or too many blocks. When installing the cutter, the fastening screw shall not extend beyond the rotation radius of the boring cutter. When the machine tool is running, it is not allowed to measure the size, check the template or touch the machined surface by hand. When boring and reaming holes, it is forbidden to observe the situation of eating knives with your head close to the machining hole, and it is forbidden to take things through the rotating boring bar. When using the self-made flat rotary cutter head to cut, the screws should be tightened, and it is forbidden to stand opposite or watch, in case the cutter head screws and inclined iron are thrown out to hurt people; Special attention should be paid to prevent strangling clothes from causing accidents. When the workbench starts to rotate automatically, the boring bar must be retracted, and no one is allowed to stand on the workbench.
