In order to ensure the safety and efficiency in the process of CNC precision hardware parts processing, this paper summarizes the CNC precision hardware parts processing process for the reference of personnel engaged in machining industry, the specific matters are as follows:

1、 First of all, to ensure the safety of the operator, the operator must obtain the work license before taking up his post. In the CNC precision hardware parts processing, the operator must pay attention to, can not be distracted, can not be tired operation, the machine is not stopped, can not enter the machine interior; the operator is not allowed to leave long hair, wear shoes, any impact on the safety of clothing are not allowed.

2、 Before machining CNC precision hardware parts, the equipment of the machining center should be inspected. The inspection items include whether the lubricating oil is qualified, whether the clutch and brake are normal. After the machine tool idles for 3 minutes, the machining can be carried out. If there is any abnormal phenomenon, the machine must not be started up.

3、 Check the CNC precision hardware parts machining machine table, confirm that there is no foreign matter, start the power switch, start the processing operation.

4、 In the process of CNC precision hardware parts processing, it is forbidden to take parts by hand when the machine is not stopped stably. In the process of operating the machine, no one is allowed to start the machine button, and two people are strictly forbidden to operate one machine at the same time.

5、 During the operation of the machine tool, the machine must be stopped immediately to check if the cutting amount is too large and the machine tool is overloaded. Before the problem is solved, it is not allowed to start the machine again. Otherwise, the machining quality of CNC precision hardware parts will be affected and the service life of the machine will be seriously affected.

6、 CNC precision hardware parts processing is most prone to machine collision events, generally due to incorrect installation of cutting tools or workpiece, fixture installation is not locked, the occurrence of collision events, light machine damage, serious, also affect the safety of the operator, so in the process of machine tool processing, be sure to close the safety door to avoid accidents.
