BV Products: Vibratory Trough Machines

A Vibratory Tub (or Trough) Machine is older in design than the round bowl vibrator. A VT Series machine is rectangular in shape comparable to a traditional bath tub or horse trough. The primary difference between the bowl and tub is that tubs nowadays are generally dedicated to low volume production, large parts finishing. A less fundamental difference of a practical nature is that as a general rule tub machines (unless of the through feed automated type) need to have the finished parts placed manually in the machines for finishing then removed the same way. Fixturing of larger parts means that these machines are capable of finishing large heavy parts -even heavy mining equipment gears and the like. Tub vibrators can be used to finish very long parts, sometimes over 4000mm in length or the machines can be temporarily or permanently divided into a series of sections called compartments – the sizes of which can be varied longitudinally to suit varying component size. When very long parts are involved, or more than one type of media is needed frequently tub units are often used. Both the round and tub vibratory machines have open tops, making parts and media removal simple. “VT” range trough machines are constructed and designed for extreme, heavy duty use and comprise a rigid metal tub which is lined with “hot poured” polyurethane. The VT Series vibratory trough machines are constructed and designed for extreme, heavy duty use and comprise a rigid metal tub which is lined with “hot poured” polyurethane minimally 25mm thick. The tub or trough is mounted on a steel base. It is fitted with heavy duty vibratory motors mounted directly to tub which provide maximum efficiency in deburring processes. Adjustable OB weights & electronic variable speed control allow for infinite adjustment for all types of processes.
