Protective equipment and operation requirements for large-scale machining

Large-scale machining should wear protective equipment before work. It is prohibited to wear gloves and scarves. Before starting the machine tool during work, it is necessary to understand the purpose of each handle or operation method, and effectively check whether each part of the machine tool is operating normally.

For large-scale machining, the tool and workpiece must be clamped with a wrench before the machine tool is started. The machine tool is not allowed to be started without the permission of the instructor. 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 are foreign objects or chips found on the machine tool, it is not allowed to take it by hand or blow it with the mouth.

After the operation of large-scale machining is completed, it is necessary to clean up the tools and the working site of the machine tool in time. Do not put the tools, workpieces and other items on the machine tool and work surface during work, and no hands are allowed during work. Touch the tools, workpieces and other moving parts. Do not lean your body on the machine to avoid other accidents.

Large-scale machining requires a clear division of labor and close cooperation when two people operate a machine at the same time. When power is cut or when leaving the machine tool, the machine tool should be shut down to avoid accidents.

In the production process, those processes that are directly related to the transformation of raw materials into products are called technological processes. It includes blank manufacturing, parts processing, heat treatment, quality inspection and machine assembly. The manufacturing of tools, fixtures, and machine tool adjustment and maintenance required for the normal process of the process are auxiliary processes. In the process, the processing method of large-scale mechanical parts in Dalian gradually changes the shape, size, relative position and performance of the blanks in a certain order, until the part of the process that becomes a qualified part is called the mechanical processing process.
