Bench grinders are handy tools. They can help reshape a piece of metal, take off burrs and sharp edges and even polish the metal for you. It is all in the wheel you use. Changing the wheels from a regular grinding wheel to a buffing wheel is not hard.
How to put a buffing wheel on a bench grinder: It may take some doing but it is possible to put a buffing wheel on a bench grinder. There are a few short and easy steps to take:
But there is more to this topic. That is how you put a buffering wheel on a bench grinder but that is not all there is to it. There are some aspects you need to know to make sure you can use the buffering wheel successfully. Just continue to read our article to get the whole picture.
As you can see, it is possible to put a buffering wheel on a bench grinder. The process is not that difficult and any handyman can do it in a few minutes. Yet there are some more things you need to know before you make the switch.
First, there may be a reverse thread on the side of the bench grinder you want to place the buffering wheel. If there is, you will want to watch how you thread the wheel and the bolt.
Second, after placing the buffering wheel on the bench grinder, you may find that you do not have the space needed to polish all the angles on your project. You can add a second wheel, an arbor extender or spacer to help you get that room.
Third, 8” wheels are better than 6” ones although the latter can work well. You just need to watch how hard you press.
Fourth, all motors are not the same and if you press too hard then your wheel will get slowed down and not do a great job. A variable speed bench press may give you the power to avoid this issue.
Converting a bench grinder to be a buffer is not as simple as changing the wheels. This takes a little time and a little ingenuity to make sure you get the parts to fit and work properly.
Here is one way to make the conversion in your own workshop:
Now you have buffering wheels to make your polishing life a lot easier.
The key to using a buffering wheel on a grinder is to make sure you are safe. Safety is always king. Wear good eye protection and make sure the grinder is securely bolted to your workbench.
Next you want to keep sharp edges away from the wheel as those will catch and cause you a lot of problems. Then you need to keep the piece you are polishing cool. Have a glass or bowl of water nearby so you can dip the piece into and cool it down.
1. How safe is it to use a bench grinder as a buffering tool?
If you follow all the bench grinder safety rules, then using it as a bench grinder as a buffer is very safe.
2. What size of buffering wheel should I use?
Buffering wheels come in all sizes. It is best to try to learn how to buff on a 6 inch wheel. Then when you gain experience, move to other wheel sizes.
3. Will the buffer make the object hot to handle?
Yes, it will. Like regular grinding wheels, the buffering wheel uses friction to achieve its goal. That friction will heat up your item and you may burn yourself if you are not careful.
You can adapt your bench grinder to a buffering powerhouse with ease. The key is to make sure you get the buffering wheel tight enough that it is safe to use. Also, keep a glass, jar or a bowl of water next to your work area.
This will allow you to cool down the item you are polishing and keep you from being burned. Just follow the basic safety tips for bench grinders and you will be able to polish a myriad of items safely.
