Comprehensive knowledge about M816 grinder

The large water grinding surface grinding wheel is 800*1600, and the grinding wheel size should be 400*50*203. Then your questions: 1. The grinding wheel finishing is less than 0.005mm, and the maximum feed amount for rough grinding does not exceed 0.03mm. 2. There is 46K on the label of the grinding wheel. The K in 80K100K120K refers to the combination of the grinding wheel and the hardness of the grinding wheel. Generally, the "k" grade hardness is used for steel below 55HRC. 3. The black one specially designed for grinding tungsten steel

How to repair grinding wheels made of copper? Step 1. Reduce the grinding wheel speed. In principle, reduce it to at least half to make it easier to repair. If there is no frequency conversion, you can repeatedly turn the machine on and off to reduce the speed for repair!

Step 2. Grind the dressing tool with a grinding wheel, moving the overlapping surface back and forth to be 1/3 to 1/2 of the width of the grinding wheel.

Step 3. Advance the knife successively, taking 140# as an example, advance 0.005, make a dull sound to a crisp sound, jump to a flat surface, then advance to 0.01 and repeat,

Check the surface, and then proceed to 0.015, 0.02, 0.025, 0.03 in sequence until there is a crisp sound, a flat surface, and no chatter marks, indicating that the rounding and sharpening are completed

. The maximum dressing feed amount needs to be adjusted depending on the grinding wheel particle size. The coarser the particle size, the greater the dressing feed amount!

Note 1. You can use an oil-based magic pen to apply it on the circumference of the grinding wheel in advance. When the ink traces completely disappear, it means that the rounding work is completed.

Note 2: If there are chips during grinding, you can hold the sand bar for sharpening to restore the cutting function of the grinding wheel!

Note 3: After rounding the centrifugal brake, it must be sharpened with white sand strips.

Note 4: Once the diamond and boron nitride grinding wheels are installed on the machine, it is best not to remove them unless they are completely worn. If it must be removed, it must be removed together with the

Note 5 flange, otherwise more repairs will be required once it is reused!
