Brushed Satin Finish

If you need to put a satin finish on stainless steel hand rails, then Time Saving Kit 3 is the ideal choice.

Included in the kit is all you need to remove a weld (or any scratches, damage or even heavy grinding marks) and put a high quality fine ‘shopping centre’ standard satin finish on your stainless handrails.

The answer is a simple yes. Different grades of metal require specific speeds to optimise the cutting, sanding and finishing processes.

–  Stainless steel will work harden if you grind at too high a speed or pressure.  It will also cause the abrasive to glaze over which will in turn cause heat generation to increase. Lowering the speed will allow the abrasive to cut more effectively and increase the lifetime of the disc.

–  Aluminium has a different problem.  Aluminium has a lower melt temperature so if you grind at too high a speed the metal will begin to plasticise and ultimately melt.  The plasticised aluminium will stick to the abrasive sanding belt, disc or pad causing it to clog up.

Consider a drill.  Nobody would try to drill through steel, or stainless steel or aluminum at the same cutting speed; abrasives are no different.

A variable speed grinder will reduce the grinding heat, increase the process control, reduce re-working and ultimately save money on your abrasive consumables as they can last much longer when used at the correct speed.
