Tumble Finishing

Tumble FinishingTumble finishing is the process of polishing small rough parts en masse. The parts can be made out of a variety of materials, including stainless steel and plastics. Mass tumbling is accomplished using a variety of machines, and can take minutes or several hours depending on the part requirements. At RP Abrasives, we specialize in two types of tumbling: high-energy and vibratory.

High-energy tumbling involves placing parts, media, water and a surfactant in a barrel enclosed with a lid. The barrel is then rotated on a carousel holding four barrels. The carousel spins in one direction while the barrels spin the opposite way, creating a powerful centrifugal force that finishes the parts to the desired level.

We use four high-energy tumblers. The machine pictured has an 80-liter capacity. Our other high-energy tumbling machines are 120-liter and 20-liter. We prefer Mass Finishing Inc. machines because we find them to be extremely durable and reliable. Which machine gets used depends on the number of parts and the size of the parts.

Vibratory tumbling uses friction to smooth objects. The vibrating media against the parts create the desired finish.
