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

  • An Easy-to-Use Disc Finishing System — Centrifugal Disc Finishing Machine
  • A Centrifugal Disc Finishing Machine with an electromagnetic governor is a specialized type of finishing equipment used to smooth, deburr, and polish a wide range of parts and components. It works by using a high-speed rotating disc, or rotor, to generate centrifugal force, which acts on the parts placed in the machine. The electromagnetic governor helps to control the speed of the rotor and maintain a consistent speed during the finishing process. The electromagnetic governor uses sensors to monitor the speed of the rotor and adjust the electrical current supplied to the motor as needed to maintain a consistent speed. This helps to ensure that the finishing process is consistent and produces high-quality results. The machine also be equipped with a control panel that allows the operator to set and adjust the speed and other parameters of the finishing process.
