Corncobs for Vibratory Finishing, Tumbling and Grit Blasting

Vibratory finishing and tumbling are mass finishing processes where abrasive and absorbent characteristics are generally desirable. Corncob grit polishes and deburs parts while at the same time cleaning and drying parts. Oils and other liquids from wet mass finishing processes are absorbed. Grade selection is typically based on the finished surface profile desired and the diameter of any holes or cavities in the part. The grades available are 814, 1014, 1420 and 2040.

Grit blasting with corncob particles is accomplished with the same equipment used for sand blasting. Because corncob grit is considerably less aggressive than sand, it is often categorized as a soft abrasive (corncob grit has a 4.5 Mohs hardness). Applications include loose and flaking paint removal and plant maintenance. In addition, it is ideal for wood, aluminum and fiberglass substrates.
