Introduction for VA series Centrifugal Disk Finishing Machine

The patented adjustable gap system of the VA series enables a precision of 0.05mm.

This unique setting of the gap between the disc and the ring of the barrel make super fine polishing granulate to be possibly used as media.

The VA series model, therefore, produces the superior polishing surface with the lowest processing cost.

Besides, the customized process prevents the gap from overheating.

Working principle for VA series Jewelry Polishing Machine

The VA series machine from Inovatec work on the centrifugal disc finishing concept, it functioned with a highly effective and efficient mass finishing system.

During this process, the components are processing in a barrel-shaped container where finishing media and components make a rotational relative movement.

The media inside the container is driven by the centrifugal force of disc which generated from the bottom of the container.

The disc is separated from the container wall by an adjustable gap where the water is flowing through in the wet processing machine.

In dry processing machine for fine polishing, however, the gap is there for disc rotating.

The centrifugal force with different media act on the surface of the component gives different finishing result, which will offer at least 20 times high productivity compared with the vibratory finishing process.

During wet surface finishing processing constant water and compound flow which at meantime take off wear off debris together.

This leaves the components of a fresh and clean surface.
