Abstract: METHOD AND APPARATUS FOR MACHINING A DIFFERENTIAL CARRIER                            ABSTRACT         A machine tool and method for simultaneously boring, facing and back boring three bores in a differential carrier with three tools that rotate coaxially with their spindle axes.  Each tool has a first slide at its free end that carries a first cutting insert for back boring a first diameter and then generating a radial face that serves as a bearing seat on the differential carrier.  Each tool also has a second slide carrying a second insert for boring a second diameter.  The construction, arrangement and movement of the two slides are correlated with each other to maintain the tool in balance during extension and retraction of both slides.  In the preferred embodiment the first insert must be retracted when it is advanced into the carrier, extended to back bore and then retracted to generate a radial face.  The second insert is at the same location circumferentially of the tool. One insert is retracted while the other insert is extended, and vice versa, to maintain the tool in balance.  In this embodiment, the travel of the first slide to back bore and generate is relatively large.  Hence, for similar slides the movement of the second slide to offset the movement of the first slide is greater than would otherwise be required to bore the second diameter and clear the carrier when the tool is retracted.

Abstract: The present invention provides an improved device for and a novel method of forging a helical gear with a sufficiently high accuracy and smoothly removing the helical gear from a die without giving any damage.  An ejector of the device has a guide element which allows a screw-type movement, that is, simultaneous movement along and rotation around a vertical axis of the ejector,  The ratio of a rotational angle to a moving distance along the vertical axis in a work with a plurality of helical teeth is identical with the same in the ejector,  While the ejector moves along the vertical axis by a predetermined distance and simultaneously rotates by a predetermined angle. the work moves along the vertical axis by the same distance and rotates by the same angle.  This makes the helical teeth on the work free from an excessive external pressure and allows smooth removal of the work from the cavity of the die.
