Mass finishing

The goal of this type of finishing is to burnish, deburr, clean, radius, de-flash, descale, remove rust, polish, brighten, surface harden, prepare parts for further finishing, or break off die cast runners.

Cycle times can be as short as 10 minutes for nonferrous workpieces or as long as 2 hours for hardened steel.

Due to the random action of the processes, mass finishing is as much an art as it is a science.

[2] Media are designed for four things: Compounds are added to mass finishing processes to assist in deburring, burnishing, cutting, cleaning, descaling, and inhibiting corrosion.
