More efficient way of aligning the grinding machine

First of all, you will need some supplies

Spray the adhesive.

Oil for sanding.

I used a few pieces of coarse sandpaper to buy a bunch of big packaging from the hardware store, but more packaging is ideal. We only need a few sheets of paper of each size. Make sure it is wide enough to accommodate the burrs.

Remove the glue.

Knife. Most amateur stores, hardware stores and office supply stores have the right things.

Some rags wipe off the metal-filled cutting oil. I hope to throw them away later, so buy something cheap.

Masking tape.

The thinnest tape you can find. It must be installed between the sweeper of the burr holder and the external burr.

Screwdriver for the burr chamber and screwdriver for the burr itself. I highly recommend using a torque screwdriver to put the burrs in a more even tension. It’s not absolutely necessary, but if you can buy a cheaper product, you can be more confident, and you won’t be overly nervous.

Unplug your grinder at this point. Leave it unplugged until it is complete.

Now, to do indoor sanding


Six squares were cut out, approximately 220 grit, 320 grit, 400 grit and 800 grit sandpaper, respectively, to fit the entire burr. If you like to shine and don’t care about time, you can also throw some higher coarse sand in it.

Remove the outer burr holder from the grinder, remove the spring, and set aside. Then loosen the internal burr and you will first attach the sandpaper to the burr.

Take a square of 220 grit, then gently spray the back with a spray of adhesive and then press the internal burrs onto it. Wait for it to dry out. Then cut off the excess sandpaper from the edges and the middle, leaving only one turn.

Apply the internal burrs to the external burrs that are still screwed into the burr holder. You can use tape to cover things around the sweeper, or try using a thin tape to place the tape underneath them.

Apply cutting oil to the sandpaper.

Place the two burr assemblies into the burr chamber (make sure the spring is removed from the bracket) and rotate under gentle pressure. Remove it from time to time to wipe off oil and metal. Continue until the sandpaper is worn.

Repeat 3-6 times twice to use 3 discs. You will need to use a glue remover to clean the burrs to connect to the next 9 inch sanding disc.

Repeat steps 3-7 for each size of sandpaper. You should use at least 3 discs of 220 and 320 and may fall from there. These dimensions can do most of the work, and the rest can be polished.

Your chamber is now ground to be perpendicular to the drive shaft. But your carrier can’t match it completely.

Now used for carrier sanding


Screw the internal burrs back into the grinder. Ideally, use a torque screwdriver to make things even. Unscrew the outer burr from the bracket

Take a square of 220 grit, then gently spray the back with a spray of adhesive and then press the outer burr onto it. Wait for it to dry out. Then cut off the excess sandpaper from the edges and the middle, leaving only one turn.

Attach the external burrs without burrs to the internal burrs. Depending on the single grinder, this can be painful and you need some thin strips. This time, the cleaner bar will need to be able to be mounted on the tape.

Apply cutting oil to the sandpaper.

Place the bracket on the two burrs that are attached to the chamber, apply a moderate amount of pressure, and then rotate it to sand the bracket. The method of using the chamber is the same.

The operation was repeated with a plurality of sand grains and a plurality of discs of each sand in the same manner as the processing chamber.

Now the chamber surfaces of your carrier are parallel. Which is also perpendicular to the drive shaft! Congratulations, your angle grinder cutting discs is on the side of the machine shop!

Final steps and considerations


Don’t worry about matching my granularity number exactly. They serve as guidelines for cutting coarse sand and finishing coarse sand.

Your zero value will change significantly. We have removed the material from the two burr mounting surfaces so they will be physically separated further under the same settings until they are reset to zero.

Be sure to clean the grinder before use.

Before reinstalling the burrs, be sure to thoroughly clean the burrs.

Before using, please make sure to rinse the grinder with at least a small amount of coffee, preferably more.

When you apply spray adhesive, place it in a box or other containment area to avoid confusion.

Wiping alcohol, acetone, dish soap, etc. does not help the spray adhesive. You really need glue or oil. Believe me, I don’t think I need it.

If you use any water on the burr for cleaning, wipe it off immediately. Particularly suitable for standard uncoated diamond cutting tools steel burrs.

Once the theoretically slightly perfect surface finish is completed, you can repeat the chamber grinding, but this is not required.

The sanding time applies to standard sandpaper and should last from a few minutes to 10-20 minutes. If you use any particularly durable sandpaper and there is no wear at all for a few minutes, you can stop and continue using the next grit after a few normal sandpaper wears.

When cutting sandpaper around the burrs, be sure not to be too tight. Remember that the burr must be suitable for the matte area. If the sandpaper is cut too tightly and no burrs are exposed, the burrs will eventually land on the unpolished edges around the burrs. It can also be slightly exceeded. Therefore, if in doubt, it is best to make the 9 inch sanding disc slightly larger than needed without making the disc slightly smaller to work.
