ABSTRACT:
A machine tool attachment which provides for material handling, positioning, and clamping during machining and also eliminates the need for custom tool fixtures is described. The machine tool attachment mechanically advances material to be machined through a tubular tail stock and into a head stock. Collets located in the tail stock and head stock automatically power clamp the material and a rotary indexer automatically rotates and indexes the material during the machining operation. Once machining is completed, the material between the head stock and tail stock is further clamped by the attachment and then cut by the machine tool. Remaining material can then be advanced by the attachment and the process repeated. The machine tool attachment interfaces with a numerically controlled machining center which transmits signals to control the functions of the attachment for proper coordination with the machine tool.
