When processing stamped parts, do not open the cuffs and wear tight protective clothing. Wear a protective helmet for long hair and do not wear gloves during operation. The chuck and flower tray must have secure bolts and be tightened before use; The conical shaft chuck needs to be equipped with a pull rod. Before starting work, it is necessary to check the working condition of the lathe and promptly handle any problems found. The workpiece and cutting tools should be clamped tightly. The protruding parts of the chuck, dial, and chicken heart clamp for gripping workpieces are best protected by protective covers to avoid twisting clothes and other parts of the body. If there is no protective cover, pay attention to spacing during operation and do not approach. When changing the workpiece, it is prohibited to sand the parts with sandcloth by hand or wipe them with cotton sand. Sanding the inner holes and outer circles must be done with a hammer wrapped with sandcloth. Use hooks to promptly remove strip shaped chips and spiral shaped long chips that have been cut, and do not pull them by hand. Except for the active measuring equipment installed on the lathe, the workpiece should be parked for measurement and the tool holder should be moved to a safe position. When turning slender workpieces, to ensure safety, an intermediate frame or tool holder should be selected, and the part that grows out of the lathe should be marked. To prevent personal injury caused by debris, equipment should be equipped with clear baffles in appropriate positions.
