How to operate a precision surface grinder correctly?

Standard Operating Procedures for Precision Surface Grinding Machines

This precision surface grinder has high machining accuracy and stable quality. Due to high positioning accuracy and repeated positioning accuracy, it is easier to ensure the consistency of part dimensions. As long as the process design and procedures are correct and reasonable, the operation is careful, and the machining accuracy of the parts is high, quality control can be carried out during the machining process.

Before starting work, it is necessary to wear protective goggles, fasten clothes and sleeves, put the long hair board into the work cap, and wear gloves to operate the grinder.

Before operating the precision surface grinder, place the tools and workpieces neatly, and remove any debris that may hinder the operation of the equipment system and operational activities. Before operation, check whether the safety protection cover of the transmission part is complete and fixed, and promptly deal with any abnormal problems found.

Before starting the precision surface grinder, check whether the transmission part and operating handle are sensitive, whether the lubricating oil system management of each part is smooth, and whether the electronic ruler displays information data.

Before starting the precision surface grinder, adjust and lock the left and right convex stops according to the grinding length of the workpiece.

5. The installed grinding wheel must be statically balanced. After calibration, it should be rebalanced. The diamond of the grinding wheel dresser must be sharp, and its tip height should be consistent with the horizontal plane of the grinding wheel centerline. It is prohibited to use dull diamond to repair grinding wheels. When trimming, the vacuum cleaner must be turned on.

6. Start the precision surface grinder spindle and idle for 1-2 minutes. Observe the operation. Pay attention to the height of the grinding wheel being about 5cm away from the workbench; After confirming that the lubrication and cooling control system is unobstructed and all components are operating normally, the grinding operation can be studied.

7. Check the workpiece, load and unload the grinding wheel, and handle machine tool malfunctions. Stop the machine after removing the grinding wheel from the workpiece.

The workpiece adsorbed by the moving disc switch must be checked for its firmness after grinding. For workpieces with high or small adsorption, the appropriate height of the fixing plate should be increased to prevent workpiece loosening and potential accidents.

When the grinding wheel approaches the workpiece, it must be touched and removed in a prohibited state. When the grinding wheel has not left the workpiece, it is not allowed to stop running. The grinding feed rate should increase from small to large and should not suddenly increase. It needs to be cut evenly to prevent the grinding wheel from hitting the workpiece and breaking.

After completing the operation of the precision surface grinder, the vacuum cleaner or water tank should be turned off first. After the grinding wheel idles for more than 2 minutes, cut off the power supply to all students. Place each handle in the non working position and turn off the power. Before leaving work, the management tools and workpieces should be cleaned and neatly arranged, and the desktop and surrounding environment should be cleaned. After working continuously for a week, remove the iron filings from the vacuum cleaner or water tank.
