Double Disc Fully Automatic Centrifugal Disc Finishing Machine

This finishing machine is perfect for surface finishing, deburring, edge rounding, and shinning/polishing small and medium-sized stamping components, castings parts, and machined components.


Improved labor costs and automatic surface finishing solutions have gained daily importance with industries.

Innovatec’s various processing techniques combined with 30 years’ practical experience have completely been proven for this trend.

Areas of application

A high-energy fully automatic centrifugal disc finishing machine is excellent for deburring, surface finishing, edge rounding, and shinning/polishing small to medium-sized stamping components, castings parts, and machined components. One of the key advantages is the relatively short processing times and easy to achieve a high degree of automatic control.

Its wide application ranges from precision components to thin parts with a thickness of 0.5mm to 150mm.

Working principle

The centrifugal force of the rotating disc moves components and mass finishing media upward to the processing bowl while offering high kinetic energy to move forward. As components and media relative movement and kinetic energy loss on the way, the mass falls back at the center of the rotating disc where centrifugal force moves it again.

The process parameter can be varied according to the disc’s RPM, the water level in the work bowl, media, and compound to be used, so the processing result can vary from gentle surface grinding and polishing to fast deburring processing.

Compared with a conventional vibratory finishing machine, the centrifugal disc finishing machine provides 10 to 20 times higher productivity in respect of product production capacity.
