1. When loading and unloading workpieces, the cutting tool must be removed, and the cutting head and hand shall not approach the milling surface.

2. When the milling machine is used for tool setting, it must be moved slowly or manually, and fast forward is not allowed. When the cutter is moved, it is not allowed to stop.

3. Pay attention to whether the handle of the milling machine will hit people when rapidly advancing and retreating tools.

4. Do not feed too fast or change speed suddenly. The limit stop of the milling machine should be adjusted well.

5. The milling machine must be stopped up and down, measuring the workpiece, adjusting the cutter and fastening the speed change.

6. When disassembling and assembling the end milling cutter, the worktable shall be padded with wood, and the wrench nut of the flat milling cutter shall be removed without excessive force.

7. It is forbidden to touch or wipe the rotating parts and tools with cotton yarn, and it is forbidden to hold the cutter head by hand.

8. Generally, only one workpiece can be clamped by one collet at a time. Because more than one workpiece is clamped by one collet at a time, even if it is clamped tightly, the force during rough feeding is very large, and the two workpieces are easy to slide, resulting in workpiece flying out, knife breaking and personal injury.
