CNC drilling unit is a mechanical device driven by motor, which can realize boring, milling, drilling and other functions. CNC drilling unit is a relatively simple transmission mechanism with various forms. The basic principle is that the motor drives a gear transmission mechanism, which can realize the functions of boring, milling and drilling. In some operations with guideways, the operating rules of drilling unit are as follows:

1. Operators shall not leave their posts without authorization in the course of their work.
2. The oil pipeline of the oil pressure system should be tight and smooth, and the oil pressure, oil quantity and oil temperature should be kept within the prescribed range.
3. When the temperature is low in winter, the engine bed should be idled before the oil melts.
4. When two people operate a machine tool, the division of labor should be clear and one person should be responsible for the command, and good contact must be made before work.
5. When loading and unloading heavy workpieces, they should be coordinated by others or lifting machinery.
6. It is strictly forbidden to deliver tools, fixtures and other articles on the running machine tools or to touch the processed parts directly by hand.
7. It is strictly forbidden to use hand to cool and rotate the cotton yarn with cooling liquid.
8. It is strictly forbidden to remove the edges and corners on the machine tool and the scattered materials under shearing by hand. The banded cuttings entangled on the cutter or workpiece must be removed by hook, and must stop when clearing.
9. When operating a machine tool, no scaffolding shall be used on or on the machine tool.
10. When checking the accuracy, measuring the size, checking the changing position of the die shears or the workpiece or abnormal sound of the machine tool occurs, it must stop.
