What blade for cutting aluminum? What happens when you grind aluminum on a bench grinder? When you grind aluminum on a standard grinding wheel it will load up quickly. The aluminum is filling in the voids in the wheel and can expand and cause the wheel to explode due to internal stresses caused by the aluminum expanding.
Does grinding aluminum spark? While grinding metal, sparks are produced because of Friction. The rotating grinder cuts through the metal molecules, rubbing against them and producing heat.
Aluminium on the other hand is even softer and lighter than Iron, so there's even lesser friction and hence, lesser sparks. Can you use sandpaper on aluminum? It's recommended to use aluminum oxide sandpaper or silicon carbide sandpaper when polishing metal; aluminum oxide is the best option for polishing hard metals such as iron and steel, and silicon carbide is good for softer metals such as aluminum and brass.
Can you cut aluminum with an angle grinder? Aluminum can rapidly load up on an abrasive disk causing it to catch and explode right in your face.

Surface grinding aluminum Does anyone know of a more affordable solution to MagnaLock-MagnaVise when surface grinding non magnetic materials?
I know the obvious vacuum chuck and blocking techniques. I stop and clean out the wheel very often as my experience with this was very bad.
One of my friends loaded a stone wheel with aluminum and it shattered while running at speed and really wrecked his hand. He said that he had heard that it could happen but didn't give it a thought.
Folks, grinding aluminum is okay if you use the correct tools! Here is an example: www. If you don't use the correct tools, then grinding Al is dangerous and as posted above can cause injury. Please be safe! Hi, I am only a humble firefighter. Previously an electrical and instrument fitter. During my time as a tradie I was told never to grind brass or other soft metals on the grinding wheels designed for ferrous metals because the partials which clog the wheel can expand when they become heated during grinding, especially when grinding steel and similar metals after it has been clogged.
The expanding soft metal can apparently force the composite particles of the wheel apart in an explosive manner. This post is a little late, but these things stay on line for years until someone searching for information stumbles across the post as I have. So in the interest of safety please consider this post.
This may not be correct, so be cautious and do more searching. I've been a CNC machinist for about 10 years. Grinding aluminum is not commonly done because its pretty rare that you find an application where you can't machine it due to hardness issues.
Its also fairly rare to need the precision from grinding on aluminum pieces but formula engines do need that precision. I bet if you do a search you will find good information on the process but from what i know, they have special surface grinders that run a silicon carbide wheel and special coolant to surface grind cylinder heads and blocks to within.
Comment Post Cancel. Fasttrack: The information that you mentioned was what I was able to find. The wheel that is used is a silicon carbide but it did not mention the coolant. I use one of the Norton silicon carbide grinding wheels to surface the magnetic chuck on my grinder. It does a great job if your careful. I will be looking into adding coolant. My grinder is a 6 x 12 bench model which has served me well to date.
I do it on my big mattision occasionally and the grind house where I send jobs that are to big or just dont have the time to do, grinds aluminum all the time. I was in there last week and they were grinding some big fixture plates that had a couple thousand drilled and tapped holes in them, the material was cast aluminum mic 6 and it comes blanchard ground from the supplier, but all the holes being put in make the secondary grind necessary.
When I do it I dont put on a special wheel or anything, but I do have kind of a general purpose grinding wheel. Just use lots of flood coolant and make sure the part is blocked in really well, since aluiminum magnets havent been invented yet. Yeah i think the most important part is a coolant that is appropriate for aluminum.
