The maintenance and upkeep of the double end face grinder should be carried out systematically from three aspects: daily operation, regular maintenance, and safety protection. The following are the specific methods:

一、Daily operation and maintenance

1、Cleaning management

Thoroughly remove metal shavings and oil stains from the surface of the grinding disc and transmission components after each use to prevent impurities from affecting machining accuracy. The coolant needs to be filtered daily for impurities to avoid drying up, clumping, and blocking the pipeline. Residual grinding fluid should be promptly rinsed with clean water.

2、Lubrication inspection

Check the oil level of the guide rail daily to ensure that the lubricating grease (such as No. 32 guide rail oil or lithium based grease) covers the moving parts, and replenish the lubricating grease once a month.
The hydraulic system oil needs to be kept clean. It should be replaced for the first time after using the new machine for 3 months, and then replaced annually thereafter.

二、Key component maintenance

1、Grinding disc maintenance

Check the wear uniformity of the grinding disc every week, and immediately rectify any uneven wear; Newly installed grinding wheels need to be idle for 5 minutes for balance testing, with a maximum feed rate controlled at 0.03-0.05mm. When not in use for a long time, rust proof oil should be applied and covered with a dust cover.

2、Electrical and Mechanical Systems

Check the condition of the motor bearings every month and add lithium grease every 6 months; The circuit connection points require oxidation prevention treatment, and the emergency stop button function needs to be tested regularly. The pressure in the hydraulic pipeline should be stable within the range of 15-1500DaN, and any leaks should be immediately tightened.

三、Regular in-depth maintenance

1、Quarterly maintenance

Disassemble and clean the filter screens of the cooling water tank and vacuum cleaner, check the tension of the drive belt, and adjust loose parts such as the workbench steel cable.

2、Annual maintenance

Disassemble and lubricate the spindle bearings, and replace the seals; Calibrate the parallelism of the grinding disc. If the error exceeds ± 1 μ m, professional repair is required.

四、Safety regulations

Wear protective goggles and gloves during operation, and securely clamp the workpiece to avoid displacement during processing. Stop the equipment immediately for troubleshooting if there is abnormal vibration (>0.08mm) or abnormal response.
