Daily Maintenance Guide for Electronic Universal Testing Machine The electronic universal testing machine is the core equipment for testing the mechanical properties of materials. Standardized maintenance can extend its service life and ensure data accuracy. The following are daily maintenance points: 1、 Cleaning and maintenance (daily/once) Clean the dust and debris on the surface of the machine body and fixture in a timely manner after use to prevent particles from entering the guide rail or screw. Soft bristled brushes can be used in conjunction with anhydrous ethanol to wipe off residual oil stains on the sample. The use of corrosive cleaning agents is strictly prohibited. The debris inside the fixture teeth should be removed with a toothpick or fine brush to ensure reliable clamping. 2、 Lubrication and mechanical inspection (weekly) Apply special lubricating grease (such as lithium grease) to the moving parts such as ball screws and guide rails, and run the crossbeam back and forth to ensure smooth operation without jamming. Check if all connecting bolts are loose, especially the fixture installation location and sensor interface, to prevent abnormal data caused by vibration during testing. 3、 Circuit and sensor maintenance (monthly) After disconnecting the power supply, use dry compressed air to blow away the dust inside the control box, check if the wiring terminals are secure, and avoid poor contact. Sensors are core components that need to be handled with care and calibrated regularly (recommended once a year) to avoid sensitivity degradation caused by overload or collision. 4、 Software and Environment Management The operating software needs to regularly backup data and update official drivers to be compatible with the system. The equipment should be placed in a dry and electromagnetic interference free environment, with humidity controlled between 40% -70% and temperature maintained at 20 ± 5 ℃, avoiding direct sunlight or proximity to heat sources. 5、 Long term discontinuation precautions If the equipment is idle for a long time, it needs to be covered with a dust cover and powered on once a month (for more than 30 minutes) to prevent electronic components from getting damp and aging. Fixtures and screws can be coated with rust proof oil to prevent rusting. Maintenance significance: Standardized maintenance can effectively reduce mechanical wear and circuit failures, ensure the accuracy and repeatability of test data, and extend equipment life by more than 30%. It is recommended to establish a maintenance ledger to record maintenance time, projects, and abnormal situations for easy traceability and preventive maintenance. Through the above measures, the electronic universal testing machine can always be in the best working condition, providing reliable support for material testing.
