Combined chucker and bar machine

A break away machine tool assembly includes a support to which a bearing plate is pivotally mounted in overlying and contiguous relation. A tool element overlies and is contiguous the plate and is movable therewith. Securement elements releasably secure the plate and the tool element in overlying relation to the support for permitting the plate and the tool element to move relative to the support within a defined range upon being subjected to an impact.

Break away tool element and method of mounting

This invention pertains to a head stock assembly for a chucker and bar machine which includes a special bearing system comprising three forward bearings and two rearward bearings for providing five point contacts to the spindle for maintaining stiffness and rigidity and improved accuracy in machining. It also includes cooling fin means for dissipating the heat about the bearings which would normally build up in a headstock after long periods of operation. The heat dissipation reduces growth of the headstock and therefore improves accuracy. In addition, the headstock assembly has mounted directly thereon a spindle encoder, a brake disc, a collet closer mechanism, a balancing disc, as well as a low pressure means for preventing cutting fluids and dust and dirt from entering into the bearing mechanism.
