Maintenance of CNC machine tools

1. Clean and maintain the CNC machining machine half an hour before going to work every day. If you use an air gun or oil gun to clean the chips, there must be a knife on the spindle.

It is forbidden to blow the spindle taper hole with an air gun or oil gun to avoid small particles such as chips from being blown into the spindle hole and influence the cleanliness of the spindle. Dongguan CNC machining has higher production efficiency in the case of multiple varieties and small batch production, which can reduce the time of production preparation, machine tool adjustment and process inspection, and reduce the cutting time due to the use of the best cutting amount.

2. Check whether the lubricating machine is working normally, whether the lubricating oil is sufficient, and start it in the normal order.

3. Start the spindle (speed of 501R/M) to preheat the spindle before the CNC machining machine is officially working. Shenzhen CNC machining is actually a numerical control milling machine. In Guangzhou, Jiangsu, Zhejiang and Shanghai, it is called a "CNC machining center", which is an automated machine tool equipped with a program control system. , (Numerical Control Machine Tool) is the abbreviation of Computer numerical control (Computer numerical control), which is an automated machine tool controlled by a program. The control system can logically process a program with control codes or other symbolic instructions, and decode it by a computer, so that the machine tool can operate and process parts. The rough material is processed into semi-finished finished parts by cutting tools.

B.cnc CNC machining machine operation control

1. Check the procedure sheet to confirm the model, size and machining allowance of the processed blank before starting the machine, and perform de-sanding and polishing (chǔ lǐ) on the blank.

2. After getting on the machine, confirm the position of the workpiece and the processing sequence to complete the comparison.

3. If necessary for centering; centering rod; for centering, the speed is 501R/M. For centering with a knife, the speed depends on the tool. In this process (guò chéng), attention must also be paid Take the number at the same height to ensure the accuracy of the scoring. It can be used after the scoring is completed; G0 G54 X0 Y0" for inspection.

4. Before formal processing, let the programmer finally confirm whether the position of the workpiece and the number of fetches are correct.
