What Safety Issues Need To Be Addressed In Turning Operations?

Turning is one of the most widely used in the machinery manufacturing industry. The number of lathes and worker are large, the processing range is wide, and the tools and fixtures used are numerous. Therefore, the safety technical problems of turning processing are particularly important. This article will give you a detailed introduction to the safety priorities that need to be addressed in turning operations.

1. chip damage and protective measures

The various steel parts processed on the lathe have good toughness, and the chips generated during turning are rich in plastic curl and the edges are sharp. When cutting steel parts at high speed, red hot and long chips will be formed, which is very easy to injure people. At the same time, it is often wrapped around the workpiece, turning tool and tool holder. Therefore, it is necessary to clean or break the iron hook in time. It should be stopped when it is parked, but it must not be removed or broken by hand. In order to prevent chip damage, it is often used to reduce chip breaking, control chip flow direction measures and add various protective baffles. The chip breaking measure is to grind the chip breaker or step on the turning tool; using a suitable chip breaker, a mechanical clamping tool is used.

2. the loading of the workpiece

In the process of turning, there are many accidents that damage the machine tool, break or crash the tool due to improper loading of the workpiece, and the workpiece falls or flies out. Therefore, in order to ensure the safe production of turning, special care must be taken when loading the workpiece. For the parts of different sizes and shapes, the appropriate fixtures should be used. The connection of the three-jaw, four-jaw chuck or special fixture and the spindle must be stable and reliable. The workpiece should be stuck and clamped, and the large workpiece can be clamped with a sleeve to ensure that the workpiece rotates at high speed and the force is not displaced, does not fall off and does not fall out. If necessary, it can be reinforced with a top, a center frame, etc. Remove the hand immediately after clamping.

3. safe operation

Before the work, check the machine tool thoroughly and confirm that it is good. The loading of the workpiece and the tool ensures that the position is correct, firm and reliable. During the machining process, the tool must be stopped when changing tools, loading and unloading workpieces, and measuring workpieces. Do not touch or wipe with a cotton thread while the workpiece is rotating. To properly select the cutting speed, feed rate and depth of effort, no overload processing is allowed. No workpieces, work tools and other debris shall be placed on the machine bed and knife holder. When using the 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 sleeve from getting caught. The machine tool must have a person responsible for use and maintenance, and other personnel must not use it.
