SIMULTANEOUSLY COMPLETE TWO PROCESSES
IN ONE PIECE OF VIBRATORY EQUIPMENT  The Roto-Finish Multi-Pass® machines are specifically designed to meet the individual customer's parts processing needs. Each machine has a specific channel width to accommodate specific parts, and a definitive channel length to provide the required process time. The channels maintain even sequencing of parts resulting in consistent part finish and virtually eliminating part-on-part impingement. The unique design of the Multi-Pass® permits integrations with other manufacturing processes, such as casting, grinding, and stamping. Parts can be fed continuously; all parts run at the same speed; and no time is lost loading and discharging. Media capabilities include ferrous and non-ferrous metals, plastics, wood, ceramics, and cobmeal. This means that a Multi-Pass® machines can be designed to provide several different mass finishing processes, including cleaning, ball burnishing, deburring, deflashing, prepaint finishing, washing and drying. Multi-Pass® machines require less media than conventional vibratory equipment as the need for cushioning between parts is reduced by precise sequencing. The specially designed channels in the processing chamber permit a variety of cycle times ranging from 2 to 30 minutes, depending on part size, machine size, and desired finish. Standard operating features include: - cartridge drive system (triple drive on largest machines); - adjustable drop-on eccentric weight system; - continuously monitored oil recirculation; - compound flow-through system; - built in parts / media separation - quick-change, straight line screen decks; - limit switches at hinged access doors - controls which include fusible disconnect (110v control circuit), completely prewired to the machine, and totalizing hour meter; - multiple pop-in drains; and - compact settling tank.
Optional Features The Roto-Finish Multi-Pass® is available with many of the same options as our Spiratron® series machines. These include: - media classification - rinse bar or rinse station - recirculating inhibit rinse - air knife over separation screen - combo / dryer channel(s) - vacuum drains - vacuum media return (cobmeal only) - gazebo noise cover - Duskolector® with plenum - system integration
