There are many risks in CNC milling process, including mechanical injury, electric shock hazard, noise and vibration, tool and cutting debris splash and so on.

‌1, mechanical injury ‌ : CNC milling machine in the operation process will rotate at high speed, if the operation is not skilled or accidentally put the hand into the machine, it may cause clamping, cuts and other mechanical injuries ‌.
‌2, danger of electric shock ‌ : CNC machine tools usually need electric power to drive, if damaged wires or equipment failure to leak electricity, may cause electric shock accident ‌.
3, noise and vibration ‌ : CNC machine tool operation will produce large noise and vibration, long-term exposure to this environment may cause hearing damage, and may cause fatigue and discomfort ‌.
4, tool and cutting debris splash ‌ : CNC milling process will produce high-speed splashing cutting debris and tools, if improper protection measures or misoperation, may cause injury ‌.
In order to ensure safety, operators should strictly follow safe operating procedures, use appropriate personal protective equipment, such as protective glasses, ear plugs, etc., and regularly check and maintain equipment to reduce these risks. In addition, for the dust and harmful gases that may be generated in CNC milling processing, corresponding protective measures should also be taken, such as wearing masks and ear mugs, and ensuring that the working environment is well ventilated to protect the health and safety of the operator ‌.
