Abstract: The process for securing a machine tool bed to a base includes the steps of providing a base having a horizontally disposed first surface wherein a plurality of cooperating grooves are disposed. A selected quantity of hardenable grout material is deposited into the grooves. A bed has a second surface from which a plurality of tongues extend, and each tongue has side surfaces which are relatively rougher than the associated distal surface. The bed is horizontally positioned above the base so that each tongue is received in an associated groove and each distal surface is spaced from the associated underlying groove, thereby causing the grout material to rise by an amount insufficient to contact the second surface. The bed is maintained spaced above the base until the grout material has hardened and thereby binds each side surface but not the associated distal surface to the base.

Abstract: 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.
