Abstract: A surface finishing apparatus for in-line outer surface finishing of elongate cylindrical tubing. The tubing, such as tubing, is fed onto an elongate mandrel and through the finishing apparatus from an infeed to an outfeed position and rotated on the mandrel on its longitudinal axis. The outer surface of the tubing is finish treated as the tubing is fed through the apparatus while being supported on the mandrel. The finishing apparatus includes a rotatable finishing wheel having a finish-treating peripheral surface for being applied in an in-line orientation against the outer surface of the tubing as the tubing is simultaneously fed and rotated through the finishing apparatus. The wheel is mounted on an axis of rotation which is variable within a predetermined range of motion from one side to the other of the longitudinal axis of the tubing and oscillates back and forth within the predetermined range of motion while in continuous contact with the tubing.

Abstract: A surface finishing apparatus for in-line outer surface finishing of elongate cylindrical stock. The stock, such as tubing, is fed through the finishing apparatus from an infeed to an outfeed position and rotated about its longitudinal axis. The outer surface of the stock is finish treated as the stock is fed through the apparatus. The finishing apparatus includes a rotatable finishing wheel having a finish-treating peripheral surface for being applied in an in-line orientation against the outer surface of the stock as the stock is simultaneously fed and rotated through the finishing apparatus. The wheel is mounted on an axis of rotation which is variable within a predetermined range of motion from one side to the other of the longitudinal axis of the stock. The finishing wheel is oscillated back and forth within the predetermined range of motion while in continuous contact with the stock.
