Centrifugal Disc FinisherThe 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. Features: - Seal design accommodates a wide variety of parts and media sizes. - Օ Choice of smooth or ribbed polyurethane lining. - Power separation of parts, media and fines. - Օ PC control panel with process timer and hour meter. - 1800 rpm, 230/460 V, 3 phase, 60 Hz main drive motor. - Օ Helical bevel gear box. - Electrically controlled compound solution system with water flow meter and flow control processing and shutdown functions. - Օ Programmable control, will shutdown the machine automatically if the solution flow rate is insufficient. - Custom urethane linings for specific applications. Summary of Benefits: - Օ Centrifugal action is approximately 15 times faster than traditional vibratory finishing. - Cooler, more cushioned mass reduces part damage. - Օ Unique seal design reduces intrusion of smaller parts and media, thus extends service life of rotor. - Wider range of surface finishes attainable with a given media. - Օ Provides high energy deburring, descaling and improving surface finishes. Models & Options Roto-Max® Up-Flow® units are available in 1, 2, 3 and 6 cubic-foot models.Available either as a fully automatic batch finishing system, a semiautomatic system (power separation), or manual (parts to be hand-picked).

These individuals report to the chief engineer in order to provide the most up-to-date technical advise and service. Sequence of Operations for the Automatic Model For the Roto-Max® automatic processing system, the sequence of operation is as follows. - ͕ Parts and preselected media are placed into the loading hopper. - On command, the hopper is elevated and transfers its contents into the processing chamber, and a rinse bar flushes the hopper with water. - Օ The controlled start-up speed of the motor begins the rotation of the rotor.
