Smarter Finishing for Smaller Parts
When accuracy, speed, and repeatability matter, disc finishing systems deliver results that traditional vibratory or barrel systems can’t match.
At ActOn Finishing, our range of centrifugal disc systems combines controlled motion, high energy, and automated separation to achieve flawless surfaces – all within a compact footprint.
Whether you’re processing intricate medical components, aerospace blades, or automotive precision parts, ActOn’s disc finishers reduce process time while improving quality and consistency.
What Is Disc Finishing and How Does It Work?
Disc finishing uses a rotating disc at the bottom of a stationary process bowl. Media and parts move in a high-energy, toroidal flow that creates constant, even contact across all surfaces.
This produces rapid surface refinement, achieving finishes comparable to high-energy centrifugal systems but with less energy use and no part impingement.
ActOn’s machines, such as the DT and DTB Series, are designed for batch processing of small to medium-sized components, offering unmatched precision and reliability.
Why Choose ActOn’s Disc Finishing Machines?
1. Compact and Automation-Ready
Disc finishers are space-efficient and integrate seamlessly into automated production lines. Optional conveyors and PLC controls ensure continuous processing.
2. Faster Cycle Times
The precise manual gap adjustment system reduces down time, reducing the process time considerably in comparison with vibratory finishing machines.
3. Consistent Results, Every Batch
Each process is programmable and repeatable. Media flow, speed, and compound dosing remain consistent for every batch. Moreover, the upper and lower ring sets contribute to achieving consistent and desired finishing results while ensuring efficient operation of the machine.
4. Eco-Efficient Design
Low water and compound consumption mean lower operating costs and reduced environmental impact.
5. No Part Damage
The toroidal flow keeps parts suspended in motion, eliminating collisions – ideal for delicate or high-value components.
