In a matter of minutes this deburr tool can clean up metal, acrylic or rubber parts are finished in what could take hours or even days by hand. The finish achieved by these machines is isotropic, meaning parts are polished uniformly and evenly, something that cannot be achieved by hand. Variable speed control allow these tumbling machines to achieve whatever finish the operator desires, from a simple polish at low speed, to full scale deburring and edge radiusing.

CBF Machines from Mass Finishing vary in size from the compact, table-top HZ-12 to the super-sized HZ-330. Custom barrel sizes and specifications are available upon request. Check out our HZ Series page for the specifications on the individual models. These finishing and deburr tools are built for heavy use with industrial ball bearings and hot poured polyurethane barrel liners that can stand up to wear of running repeated finishing cycles.

CBF finishing & deburring systemCBF machines operate on the Ferris wheel principle

How It Works:

Each tumbling machine contains four barrels that are mounted to a drum. The operator fills the barrel with media, parts and water, roughly 50-90% full. During operation the entire drum of the debur tool rotates like a Ferris wheel. As the speed increases, the media and parts rub against one another randomly and repeatedly, removing even the smallest imperfections. In a matter of minutes the finishing cycle is complete and the parts are ready to be separated from the media.
