For large-scale mechanical processing, protective articles should be worn before work, and gloves and scarves are prohibited. Before starting the machine tool, you must know the purpose and operation method of each handle, and check whether each part of the machine tool is running normally, before the machine tool starts, the cutter and workpiece must be clamped with a wrench. Large-scale machining is not allowed to start the machine tool without the permission of the known personnel. Before the machine tool is started, it is not allowed to work such as speed change, chip cleaning or size measurement, and it is not allowed to touch the running part, if foreign matters or chips are found on the machine tool, it is not allowed to take them by hand or blow them with your mouth. When large-scale machining is working, if it is found that the object is loose or the equipment is abnormal, it needs to stop immediately. After the operation, the tools should be cleaned and the machine tool work site should be cleaned, do not put tools, workpieces and other items on the worktop of the machine tool. Large-scale machining is not allowed to touch tools, workpieces and other running parts with hands during work, and it is not allowed to lean the body on the machine tool to avoid other accidents. When two people operate a machine at the same time, it is necessary to have a clear division of labor and close cooperation. Control the quality of raw materials: high-quality raw materials are the prerequisite for the production of high-quality products. Our company uses 40Cr and 45 steel to manufacture gears. No matter what method is adopted, raw materials must undergo strict chemical composition inspection, grain size measurement and purity evaluation after arriving at the factory. Its purpose is to adjust the heat treatment deformation in time and improve the quality in tooth profile processing. More than 30% of the gear transmission noise comes from burrs and bumps. Some factories remove burrs and bumps before the gearbox is assembled, which is a passive way to prepare the organization for handling. It should be noted that in normalizing or quenching and tempering treatment, the furnace temperature must be kept uniform, and station appliances must be used to evenly heat and cool the workpieces. It is strictly prohibited to pile them together.
