Centrifugal Barrel Finisher - Kemet 120

Centrifugal barrel finishing machines operate on the “Ferris Wheel” principle with a one-to-one ratio of barrel rotation to turret rotation. Each of the four barrels is loaded to roughly 50-80% full of media, parts, water, and compound. During operation, rotation of the turret creates a sliding force inside the barrel. This motion causes parts and media to contact each other in random or isotropic directions. The resulting finish is consistent across the entire surface of the part. Kemet provides complete sample processing and stocks all required media and supplies.

KEMET 120 High Energy, Centrifugal Barrel Finishing Machine

The KEMET 120 is a full sized industrial finishing machine. This CBF machine can be fully customized with a touchscreen control panel, parts separator, drain pan and infrared safety curtain. HZ High Energy series Centrifugal Barrel Finishing (CBF) systems from Mass Finishing are the fastest and most economical form of finishing machine available. They are the industry workhorse in polishing, deburring and deflashing parts. From jet engine blades in the aerospace industry to heart valves and medical implants, these tumbling machines are the versatile and money-saving solution for polishing and deburring.

Isotropic Finishing or ISO Finishing

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.
