Safety Technical Issues for CNC Turning Parts

Nov. 25, 2019

Turning refers to lathe machining as part of machining. The turning machine mainly uses a turning tool to turn the rotating workpiece. Lathes are mainly used for machining shafts, discs, sleeves and other workpieces with a rotating surface. They are the most widely used type of machine tool in machinery manufacturing and repairing plants.

Safety Technical Issues for CNC Turning Parts

CNC Turning Parts

CNC Turning Parts is a method of cutting a workpiece on a lathe using a workpiece relative to the tool rotation. The cutting energy for turning machining is mainly provided by the workpiece rather than the tool. Turning is the most basic and common cutting method, and it plays an important role in production. Turning is suitable for machining rotary surfaces, and most workpieces with a rotating surface can be machined by turning.

Industry CNC Turning Parts is the most widely used in the machine building industry. The number of lathes is large, the number of people is large, the processing range is wide, and the tools and fixtures used are numerous. Therefore, the safety technical problems of turning machining appear. Of particular importance, its key tasks are as follows:

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 will easily injure people and often wrap 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 chipbreaker or step on the turning tool; using a suitable chip breaker, a mechanical clamping tool is used.

2. Loading of the workpiece. In the process of turning, there are many accidents that damage the machine tool, break or crash the tool, and the workpiece falls or flies out due to improper loading of the workpiece. 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 a 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 bed, knife holder and bed. 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.
