basic operation & features

Disc Finishing Machine Basic Operation

1. Loading Place workpieces with finishing media and compound into the disc chamber. Correct filling ensures stable and efficient finishing. 2. Sealing & Setup Close the cover securely and set parameters such as speed and processing time based on finishing needs. 3. Processing The rotating disc generates strong centrifugal force, making media and workpieces interact intensively to remove burrs, smooth edges, and polish surfaces. 4. Unloading After processing, parts are separated from media. Depending on the system, unloading can be manual or automated for efficiency. 5. Results The process delivers fast, consistent surface finishing—from aggressive deburring to fine polishing—much quicker than traditional methods.

1. Up to 15 Times Higher Performance

Generates extremely high centrifugal force, delivering finishing power up to 15× faster than traditional vibratory machines, ensuring rapid deburring, polishing, and surface improvement.

2. Optimized Work Bowl Geometry

Specially engineered disc and chamber design create powerful media flow, guaranteeing uniform finishing results, reduced wear, and consistent surface quality for all workpieces.

3. Compact and User-Friendly System Design

Features a space-saving structure with intuitive controls, making operation and maintenance simple while allowing easy integration into different workshop environments

4. Flexible Application into Automatic Production Line

Supports inverter or electromagnetic drives, enabling precise speed control and seamless connection to automated production systems for efficient large-scale finishing.
