Nu-Way offers grinding and polishing as part of our custom metal finishing offerings.
Grinding a metal part will remove burrs, deep cuts or saw marks. It also prepares the part for polishing. Polishing is a form of grinding that involves smoothing the part so that it has an even and completely flat surface.
Three Types of Grinding:
The three kinds of grinding we offer at Nu-Way are:
Vibratory
Tumbling
Polishing
Vibratory Grinding
Vibratory grinding helps minimize mechanical surface damage. The metal part is abraded by the repeated high-frequency vibrations.
Tumbling:
A common term in geology, tumbling is used here at Nu-Way to provide a smooth finish on metal surfaces. Rather than being abraded by grit or vibrations, tumbling requires the part itself and a tumbling machine to get the surface shiny and free of imperfections.
Polishing:
Polishing can remove what is left over from grinding, but is very rarely used on its own. Polishing is a less harsh method of smoothing the surface and great to use in conjunction with one of our other finishing methods.
