In CNC machine tools, most of the faults can be checked, but there are also some faults. The alarm information provided is vague or even no alarm at all, or the cycle of occurrence is long, irregular, and irregular, which brings difficulties to the search and analysis. many difficulties. For such machine tool failures, it is necessary to analyze the specific situation and conduct a patient search, and the comprehensive knowledge of machinery, electricity, and hydraulics is especially required during inspection, otherwise it is difficult to quickly and correctly find the real cause of the failure.
Abnormal machining accuracy failures: system parameters have changed or changed, mechanical failures, machine tool electrical parameters have not been optimized, motor operation is abnormal, machine tool position loop is abnormal or control logic is inappropriate, which are common causes of abnormal machining accuracy failures of CNC machine tools in production. Find out the relevant The fault point and processing, the machine can return to normal. In production, abnormal machining accuracy of CNC machine tools is often encountered. Such faults are highly concealed and difficult to diagnose.
