There is a bit more to cleaning and dressing your grinding wheels than just buying a dresser and applying a little pressure. In this section, we give you the steps you should take each and every time you go to dresser your wheels:
Tip 3: Make sure to do a ring test on the wheels before you start the cleaning and dressing process. Hidden flaws can be dangerous.
Tip 4: You should also spin the wheel by hand first. This action will tell you if the wheel is loose, wobbly or needs repair.
Tip 5: get to know your dresser. These tools are held in different ways and use different angles to do the dressing.
Getting to know your grinding wheel dresser is important. The little details involved can be the difference between a good cleaning and dressing process and a bad one. The following instructions focus on the diamond dressing tool.

After a long search, we found no instructions on how to make your own grinding wheel dressing tool. We do not doubt that it can be done, but you will need to be an expert at making tools and be able to get the right materials to clean and dress your grinding wheels properly.
The key to making your own would be in obtaining the right industrial grade diamond chips. About 3% of the industrial-grade chips are natural and real diamonds. The other 97% are synthetic diamond chips which are just about as strong. They are also cheaper to buy.
The diamond chips are essential in dressing your wheel correctly. It may not be a wise choice to make your own because of the danger involved. If the tool does not do a good job then your grinding wheels can’t do a good job either.
If you leave any materials behind, you are opening yourself up to risk if the wheel suddenly explodes. We suggest you stick with the commercially made dresser just to keep yourself from any harm and any possible injury.
One of the more important times a grinding wheel needs to be properly dressed is when someone mistakenly uses the wrong material on the wrong wheel. You should always inspect your wheels before using it to make sure you are not walking into a dangerous situation.
What dressing the wheel does is remove the clogged layer of the wheel exposing a fresh layer of grit underneath. This action reduces the wheel size, so it is best to only dress the wheel when it is really needed.
Too much dressing and you shorten the lifespan of the wheel. This means you would have to replace your grinding wheels more often and spend more money. Pick your times to inspect the wheels to make sure they remain clean but do not wear out so fast.
