ROTO-MAX

Centrifugal
Disc Finisher

The
technical and chemical engineers from Roto-Finish have perfected
the centrifugal disc technology and have produced a parts
finishing system that is second to none in the world. A bold
statement that we back up with one of the best warranties in the
business.

Simply stated,
Roto-Max® is a high speed, high energy finishing system for
deburring, surface improvements, descaling and finishing parts
made of metal, rubber or plastic. It’s a finishing machine
designed to machine tool specifications. Roto-Max® machines
reduce vibratory process cycles for deburring hard metals, rough
forgings and castings to the finishing of jewelry, hardware, and
medical implants.

Centrifugal
disc technology involves a machine consisting of a motor-driven,
saucer-shaped rotor mounted inside and near the base of a large
processing chamber. Both the rotor and the stationary lower ring are
coated with high-impact resistant molded polyurethane for extended
life.

Parts,
media and compound are loaded into the processing chamber, and the
high-speed disc rotation creates the centrifugal force that moves the
media and parts up the stationary sidewall. When the mass reaches the
apex, the force of gravity pulls the material back to the disc. The
process repeats.

The
doughnut-shaped path of the mass produces a highly efficient process
that is up to 15 times faster than our own superior vibratory
finishing process.

The
small open space between the rotor and the lower ring is the seal
gap. The patented Roto-Max® Up-Flow®
uses pressurized solution and processing compound which is forced up
through the seal to keep the seal gap area lubricated and free of
small abrasive particles, which greatly increases the seal life. This
is Up-Flow®.

Solution
in the lower chamber stabilizes the rotor, thus maintaining its
symmetrical alignment during rotation - a process known as
hydrostatic balancing. The constant cooling effect of the water on
the urethane prevents expansion and premature seal failure.

Water,
compound and contaminates are continuously drained through the
sidewall drain screens in the processing chamber. Upon the cycle
completion, the Roto-Max® Up-Flow®
allows the abrasive particles to drain down through the patented
hollow-core drive shaft in the center of the processing chamber. This
unique draining ability prevents material from entering the seal and
thus increases the seal life. It completely drains the fluid from the
mass. With other designs, processing fluid is left in the bottom of
the process chamber. This results in greater potential for media
residue and corrosion.

Roto-Max®
dry finishing units also utilize our patented
Up-Flow®. Compressed air (used in place of
solution) is forced up through the lower seal gap preventing media,
parts or other abrasive material from accumulating in the seal area.
The dry Roto-Max® Up-Flow®
is used for a variety of processes, e.g. to deburr, descale, or to
achieve high-luster finishes.
