The following points are recommended for grinding machine maintenance:
The painting line is mainly used in wooden doors, furniture, stairs, cabinets, handicrafts and other solid wood or wood products manufacturing enterprises.
2 composite wood products UV paint coating process and requirements: doing the color of the sheet metal coating processspray coating process: UV primer coating → UV curing → sanding → spray UV primer → infrared leveling → UV drying → unloading.

When the grinding machine is in place in the factory:
The loading capacity of the factory floor and the floor area of ​​the machine during operation, such as insufficient ground load, will affect the machine's reference accuracy;
The selection of oil products for hydraulic oil and lubricating oil in grinders must be done with new oil. The impurities in the old oil can easily block the smoothness of the tubing, affecting the running speed of the machine tool and the wear of the guide rails, causing the machine to crawl and the accuracy to be lost. Hydraulic oil briefly using 32 # or 46 # anti-wear hydraulic oil, lubrication rail oil using 46 # rail oil, pay attention to the type of grinder, to prepare enough oil;
Power matching of the power cord, if the wire is too thin, the wire will become hot and the load will be too heavy, which will cause the wire to trip in a short circuit, which will affect the power production of the factory;
When the machine is unloaded in place, it must ensure that the unloading equipment has sufficient bearing capacity, and the aisle is sufficient for the space where the machine tool moves, and it will not cause collision and personnel safety of the machine tool.
When the grinding machine is ready for processing:
Grinding machine installed in place to complete, check whether the tubing, wires, water pipe joints are locked;
When each power transmission part of the grinding machine is powered on, please use a manual test machine to ensure that the transmission of each part is turned on;
Please pay attention to the steering of the spindle of the grinder, if the reverse operation easily causes the looseness of the grinding wheel flange to affect the accuracy of the spindle;
The grinding wheel is matched with the processing material, and the grinding wheel is just a tool for machining the machine. Different grinding wheels need to be replaced in different materials.
The balance of grinding wheels, many companies do not understand the balance of the wheel, long-term use will intensify the damage of the spindle; resulting in the effect of grinding;
Grinding machine:
1. Check whether the workpiece is firmly attached or clamped, and the distance between the grinding wheel and the workpiece. 2. Observe the running speed of each transmission component and the feeding observation during processing to prevent accidental detection. 3. Grind the workpiece after turning or grinding. The adsorption surface of the disk and the workpiece is cleaned, but the air pressure gun is used to clean it tightly. The air pressure gun easily blows dust or water mist into the guide rail of the machine tool, resulting in wear of the guide rail. 4. Disk magnetism, oil pressure, grinding wheel, and start stop Valves, pumps, shutdown sequence is to stop the valve, pump, oil pressure, spindle, disk demagnetization.
Grinding machine routine maintenance:
1. Before finishing work, organize the grinder's workbench and the surrounding garbage. Observe whether there is any leakage of oil around the grinder. 2. Check the lubrication condition of the guide rails every week. If it is too big or too small, adjust it according to the oil adjustment indicator board. The lower grinding wheel flange performs anti-rust treatment on the nose surface of the spindle and the conical surface of the flange to prevent the spindle and flange from rusting for too long. 3. Clean the grinder cooling water tank every 15 to 20 days, every 3 to 6 months. Replace the machine guide rail lubricating oil. When replacing the guide rail, please clean the lubricant pool and the oil pump filter. Replace the hydraulic oil every year. Clean the fuel tank and the filter. 4. The grinder should be idle for more than 2-3 days. The countertops should be cleaned and dried to prevent rust on the countertops. The above are personal suggestions for machine tool maintenance. We hope that the new and old customers will give more support to our company for improvement.
