Abstract
Abstract Apparatus consisting of a feeding section and a sizing and machining section for cutting to size and then machining elongated cylindrical objects such as tubing, piping and bar stock. The feeding section accepts a long standard length of stock and feeds it into the sizing and machining section where the long length is first sized to the pre-selected desired length, cut to size, and the cut piece then has machining operations carried out upon its opposite ends whereupon it is discharged into a collection bin. The piece is sequentially moved from the cutting station to the machining station to the discharging station by means of a turret mechanism. The sizing, cutting, machining and discharging functions are carried out automatically in a timed sequence which is co-ordinated with the feeding function by means of control equipment utilizing electric, pneumatic and hydraulic control elements. Means are provided for manual operation of each function of the apparatus.
