ABSTRACT:
A combination dedimpler and deburring apparatus is provided in which tubes are serially introduced into a dedimpler machine which removes constrictions or dimples from the tube wall at the cut ends thereof to form cylindrically true ends, and then the tubes are automatically transferred to a deburring machine for the removal of burrs from such cut ends. In the dedimpler machine, the tubes are advanced to a dedimpler station where a pair of dedimpler plugs are moved by a cam arrangement into opposite ends of the tube in a precisely timed, synchronized motion to force the tube wall against cooperating press rollers and thus remove constrictions or dimples from the tube ends. The dedimpled tubes are then automatically conveyed to the deburring machine having laterally spaced brush heads which carry deburring brushes operative to remove burrs from the tube ends. The deburring apparatus includes structure for easily and accurately adjusting to tubes of different diameter and/or different length, and for adjusting the position of the deburring brushes relative to the tubes as such brushes become worn during operation.
