CNC turning parts processing is the most widely used one in the machine manufacturing industry. The number of lathes is large, the number of personnel is large, the processing range is wide, and there are many tools and fixtures used. Therefore, the safety and technical problems of CNC turning parts processing, It is particularly important, and its key tasks are as follows:
1. Chip damage and protective measures
All kinds of steel parts processed on lathes have good toughness, and the chips generated when CNC turning parts are rich in plastic curling and have sharp edges. When cutting steel parts at high speed, red-hot and long chips will be formed, which are very easy to hurt people. At the same time, they are often wrapped around the workpiece, turning tools and tool holders. Therefore, iron hooks should be used to clean or break them in time during work. If necessary When it is necessary to stop and clear it, it is absolutely not allowed to clear it or pull it off by hand. In order to prevent chip damage, measures are often taken to break chips, control the flow of chips and add various protective baffles.
2. Loading of workpieces
In the process of CNC turning parts processing, there are many accidents that damage the machine tool, break or crash the tool, and the workpiece falls or flies out due to improper clamping of the workpiece. Therefore, in order to ensure the safe production of CNC turning parts, special attention must be paid when clamping workpieces. The workpiece should be clamped and clamped, and the large workpiece can be clamped with a sleeve to ensure that the workpiece does not shift, fall off and throw out when it rotates at high speed and is subjected to cutting force.
3. Safe operation
Before working, the machine tool should be fully checked and confirmed before use. The clamping of the workpiece and the tool ensures that the position is correct, firm and reliable. During the processing of CNC turning parts, it is necessary to stop when changing tools, loading and unloading workpieces, and measuring workpieces. The workpiece should not be touched by hand or wiped with cotton silk while it is rotating. It is necessary to properly select the cutting speed, feed rate and labor depth, and do not overload processing. Workpieces, tool fixtures and other sundries shall not be placed on the head of the bed, tool rest and bed.
