Deburring Metal Grinding Centrifugal Drum Polishing Machine

Centrifugal drum grinding machines combine high-speed rotation with a tilting drum action to deliver aggressive deburring and edge grinding on batches of machined and cast metal parts. The centrifugal force presses media hard against the workpiece, cutting burrs and flash in a fraction of the time of vibratory finishing.

Typical work includes heavy burr removal on turned and milled steel parts, gate and flash removal on die castings, descaling after heat treatment and pre-plate surface preparation. Adjustable speed lets the same machine run from aggressive grinding down to fine pre-polish.

Longyanxing centrifugal drum machines use thick PU linings, frequency-controlled drives and safety interlocks for continuous production. Send us sample parts for a free finishing trial and cycle-time report.

Frequently Asked Questions

What is centrifugal barrel finishing?

Centrifugal barrel finishing places drums of parts and media on a rotating turret. As the turret spins, each drum counter-rotates, generating a strong centrifugal force that presses parts and media together. The high pressure produces very fast deburring, edge radiusing and surface refinement, often with near-polished results in short cycles.

What cycle times can centrifugal barrel finishing achieve?

Because the process runs at many times the force of barrel tumbling, cycle times are typically measured in minutes rather than hours for deburring and edge radiusing, with longer cycles reserved for high-gloss polishing. This makes it a strong choice for high-volume production where throughput is critical.

Which materials can be processed in a centrifugal drum polisher?

It handles steel, stainless steel, aluminium, brass, copper, zinc and many hard alloys, as well as cast, forged, machined and stamped parts. The process is especially effective on parts that need consistent edge radiusing and surface refinement in large batches.
