Troubleshooting of CNC machine tools

In CNC machine tools, most of the faults have data to check, but there are also some faults that provide vague or even no alarm information, or have a long, irregular, and irregular occurrence period, which brings many difficulties to search and analyze. For this type of machine tool malfunction, it is necessary to analyze the specific situation and patiently search for it. In addition, comprehensive knowledge in mechanical, electrical, hydraulic and other aspects is particularly needed during inspection, otherwise it is difficult to quickly and correctly find the true cause of the malfunction.
Abnormal machining accuracy faults: System parameters change or modify, mechanical faults, machine tool electrical parameters are not optimized, motor operation is abnormal, machine tool position loop is abnormal, or control logic is inappropriate. These are common causes of abnormal machining accuracy faults in CNC machine tools in production. By identifying relevant fault points and handling them, the machine tool can be restored to normal. In production, it is common to encounter faults with abnormal machining accuracy of CNC machine tools. This type of fault has strong concealment and is difficult to diagnose.
