Use the spiders - 81 b for nc machine tool spindle vibration fault diagnosis

Use the spiders - 81 b for nc machine tool spindle vibration fault diagnosis - 2020 01 - 11 Li Zuwen ( Hangzhou sharp da digital technology co. , LTD. ) Project introduction: a company CNC machine tool factory test, main shaft failure, need for fault diagnosis of machine tool spindle. Hangzhou sharp company to offer a solution according to customer requirements, the vibration tester for machine tool spindle vibration testing and characteristic spectrum analysis, generate fault diagnosis report, find out the cause of the problem. Testing equipment: spiders - 81 b vibration analyzer ( 4 channel vibration control instrument) Non-contact laser displacement sensor test content: failures in a type of machine tool spindle set up three points, respectively is the main shaft, flange, motor, through the spiders - The 81 b and laser displacement sensor for machine tool monitoring and data acquisition. Dynamic get multiple speed under vibration data, real-time, through the analysis of the fault diagnosis for the EDM software generates vibration spectrum graph report, analysis of the mechanical fault reasons, eventually produce a user report. Scene image: test results: according to the crystal diamond instruments of EDM software export of mechanical fault diagnosis report, analyzing the characteristic frequency of machine tool spindle, combined with the corresponding mechanical structure, basically can locate fault was caused by a spindle dynamic imbalance, to prevent affect precision of machine tools, threatening the safety of site personnel and guarantee the normal operation of the production, need to balance correction into action.
