Safety technology and protective measures for turning processing

Turning processing is one of the most widely used in the machine manufacturing industry. There are a large number of lathes, a large number of personnel, a wide range of processing, and many tools and fixtures are used. Therefore, the safety technology of turning processing is particularly important. , Its key tasks are as follows:

Injury and protective measures of cutting chips

The toughness of various steel parts processed on the lathe is good, the chips produced during turning are full of plastic curl, and the edges are relatively sharp. During high-speed cutting of steel parts, red hot and long chips are formed, which are very easy to hurt people. At the same time, they are often wound on the workpiece, turning tools and tool holders. Therefore, iron hooks should be used to clean up or break them in time during work. It should be stopped to remove it when it is time, but it is never allowed to remove or pull it off by hand. In order to prevent chip damage, chip breaking, chip flow control measures and various protective baffles are often taken. The chip breaking measure is to grind chip breakers or steps on the turning tool; use a suitable chip breaker and mechanically clamp the tool.

Installation of the workpiece (Guide: Silicon molybdenum rod technology and its production method)

In the process of turning, there are many accidents that damage the machine tool, break or break the tool, and cause the workpiece to fall or fly out due to improper clamping of the workpiece. Therefore, in order to ensure the safe production of turning processing, special attention must be paid when loading the workpiece. For parts of different sizes and shapes, you must choose appropriate fixtures, regardless of whether the three-jaw, four-jaw chuck or the connection between the special fixture and the spindle must be stable and reliable. The workpiece must be clamped and clamped. The sleeve can be used to clamp the large work piece to ensure that the work piece does not shift, fall off, or throw out when the workpiece is rotated at high speed and cut. If necessary, use the center frame, center frame, etc. to enhance the clamping. Remove the handle immediately after the card is tightened.

Safe operation

Check the machine tool thoroughly before work and confirm it is good before use. The clamping of the workpiece and the tool ensures the correct position, firmness and reliability. During the machining process, the machine must stop when changing tools, loading and unloading workpieces, and measuring workpieces. The workpiece should not be touched by hand or wiped with cotton silk when rotating. The cutting speed, feed rate and strenuous depth must be selected appropriately, and overload processing is not allowed. Workpieces, fixtures and other sundries are not allowed to be placed on the head of the bed, the knife rest and the surface of the bed. When using a file, move the turning tool to a safe position, with the right hand in front and the left hand in the back to prevent the sleeves from being caught. The machine tool must have a dedicated person responsible for use and maintenance, and other personnel must not use it.
