Clear division of labor and quality requirements for large-scale machining

Large-scale machining should wear protective equipment before working. It is forbidden to wear gloves and scarves. Before starting the machine tool, you must understand the purpose and operation method of each handle, check whether all parts of the machine tool are running normally, and clamp it with a wrench before starting the machine tool. Tools and workpieces.
Large-scale machining is not allowed to start the machine tool without the permission of the knowledgeable 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 there is foreign matter or inaccurate chip cutting on the machine tool Take it with your hands or blow with your mouth.
When large-scale machining is working, if you find that the object is loose or the equipment is abnormal, you need to stop immediately. After the operation, you should clean up the tools and clean the working site of the machine tool. Do not put the tools, workpieces and other items The work surface of the machine tool.
Large-scale machining is not allowed to touch tools, workpieces and other moving parts by hand during work, and it is not allowed to lean on the machine to avoid other accidents. When two people operate the same machine at the same time, they must have a clear division of labor and close cooperation. .
Control the quality of raw materials: High-quality raw materials are a prerequisite for the production of high-quality products. The materials used by our company are 40Cr and 45 steel to make gears. Regardless of the way, the raw materials must undergo strict chemical composition inspection, grain size determination, and purity evaluation after they arrive at the factory. The purpose is to adjust the heat treatment deformation in time to improve the quality of the tooth profile processing.
More than 30% of gear transmission noise is caused by burrs and bumps. Some factories remove burrs and bumps before the gearbox is assembled, which is a passive way to prepare for the organization. It should be noted that in the normalizing or quenching and tempering treatment, the furnace temperature must be kept uniform, and the work-position equipment must be used to uniformly heat and cool the workpieces, and it is strictly forbidden to stack them together.
