Grinding Aluminium
As many fabricators will be aware, grinding and sanding aluminium and many aluminium alloys can be difficult due to its low melting point and its tendency to load up abrasive products. Stategies to deal with this include:
1. Use an anti-static lubricant such as Alu-Grind on the disc or belt surface.
2. Slow down the speed, using a variable speed machine with a good lower speed torque, such as FiniPower. 
3. Use specialised coated and non-woven products such as UC grade Rapid Combi Discs.
