Can You Grind Aluminum on a Bench Grinder? (How
When you try to grind aluminum on a stone grinding wheel, the aluminum will heat up and melt. The melted aluminum attaches itself to the open pores on the grinding wheel and covers it up so it cannot effectively grind any more. After that takes place, the melted aluminum is what comes in contact with the aluminum you are holding. More heat is produced and your aluminum piece is melted again/ This causes more melting and more clogged pores on the stone grinding
