As an important processing method in precision factories, surface grinders must formulate strict process specifications. Rigorous and standard operations can ensure the stable accuracy and quality of processed parts. The operation process specification of the surface grinder in this article can be used as a standard reference for the factory.

1. First of all, you must be familiar with the operation of the surface grinder and understand the performance of the surface grinder.

2. Before turning on the machine, you must wear protective glasses, wear work clothes, fasten your clothes and sleeves, and put your long hair into your work cap. Do not wear a scarf or wear gloves to operate the grinder.

3. Before operation, tools, measuring tools, and workpieces should be placed neatly, and any debris that hinders the operation of the equipment and operations should be removed. Before operation, check whether the safety cover of the transmission part is complete and fixed. If the surface grinder is found to be abnormal, it should be dealt with in time.

4. Before starting the machine, check whether the transmission part and operating handle of the surface grinder are normal and sensitive, to see whether the lubricating oil system is unblocked, and whether the electronic ruler displays data.

5. Before starting the machine, the limit stop of the left and right striker should be adjusted according to the grinding length of the workpiece and locked.

6. The installation of the grinding wheel must be statically balanced. After correction, it should be balanced again. The diamond of the grinding wheel dresser must be sharp, and the height of the sharp point should be consistent with the horizontal plane of the center line of the grinding wheel. It is forbidden to use blunt diamonds to dress the grinding wheel. vacuum cleaner.

7. Start the grinding machine spindle idling for 1 to 2 minutes, observe the operation, pay attention to the height of the grinding wheel about 5 cm from the table surface; confirm that the lubrication and cooling system is unblocked, and all parts are running properly before starting the grinding operation.

8. Check the workpiece, load and unload the grinding wheel, and deal with the machine failure. The grinding wheel must be moved away from the workpiece and then stop.

9. It is not allowed to place non-processed items on the working surface, workpiece, and electro-magnetic disk, and it is prohibited to knock and calibrate the workpiece on the working surface, permanent magnetic chuck.

10. When moving the disk switch to pick up the workpiece, it must be checked for firmness before grinding. When adsorbing higher or smaller workpieces, an appropriate height of the supporting board should be added to prevent the workpiece from loosening and causing hidden accidents.

11. When the grinding wheel is close to the workpiece, the workpiece should be touched in a prohibited state while being moved away. When the grinding wheel does not leave the workpiece, it is not allowed to stop. The grinding feed rate should be increased from small to large without sudden increase, and the knife should be cut evenly. , In order to prevent the grinding wheel from hitting the workpiece and breaking.

12. When operating, you must concentrate and do not do anything that has nothing to do with processing. Do not leave the grinder, do not use air pressure to blow the table surface after grinding the workpiece, prevent dust from entering the surface grinder track and affect the feel and accuracy, and do not allow others to operate the grinder or Allow people to walk around the machine tool. Especially on the side of the grinder.

13. After the operation is completed, first turn off the vacuum cleaner or the water tank, leave the grinding wheel idling for more than 2 minutes, cut off the power supply of all surface grinders, put the handles in the non-working position and turn off the power. Before leaving get off work, clean up tools and workpieces and place them neatly, and do a good job of cleaning the surface of the grinder and the surrounding area. After working continuously for a week, remove the iron filings from the dust suction box or the water tank. Do the above points and you will basically be able to operate the surface grinder technology.
