Definitions

  • the present invention relates to abrading machinesand is more particularly concerned with abrading machines of the vibrating type in which unfinished-partsare'commingled with various types of finishing or polishing material in the machine housing, vibrated until the parts have a desired finish or polish, and then discharged therefrom.
  • abrading machines In recent years there has been a tremendous increase in the demand for abrading machines. This has been brought about by several factors. First, with the high cost of labor, a demand has arisen to improve the types of abrading machines presently on the market.- Second, with the introduction of large vibrating type abrading machines, it is possible to complete the finishing operation in a relatively shorter time than was possible with the tumbling barrel type of abrading machines. Moreover, the vibrating type of abrading machines makes it possible to produce a finished or polished surface which is superiorto the finished or polished surface obtainable by the tum- :bling barrel method.
  • Typical operations which are performed by the selfseparating finishing machine according to the invention are, for example, vibrating a mass of unfinished parts and abrasive material for removing burrs and the like, vibrating a mass of partially finished parts and fine abrasive material for improving the surface of the parts, or vibrating a mass of semi-finished parts and burnishing material for imparting a high grade finish or luster to the surface of the parts.
  • Another object of the present invention is to provide an improved self-separating finishing machine which is advantageous over any previously existing machine in numerous ways. 7
  • a further object ofthe present invention is to provide an improved self-separating finishing machine employing adjustable means disposed in the housing for controlling the fiow of finished parts and finishing material from an abrading compartment.
  • Still another object of the present invention resides in an improved self-separating finishing machine having adjustable means which can be regulated from the outside of the housing for controlling the flow of finished parts and finishing material from an abrading compartment.
  • An additional object of the present invention resides in an improved self-separating finishing machine having a foraminous member mounted in a housing at an angle to the vertical axis of an abrading compartment.
