摘要： In a two-axis turning machine, the cutting tool unit machines a first diameter of a workpiece portion of barstock extending from a main spindle chuck. A special subspindle chuck rotating in the same direction advances axially, grasps the workpiece as it is cut off from the barstock, and retracts. The barstock is fed through the first chuck for subsequent first operation machining and located against a stop which is independent of the tool slides. The subspindle chuck rotation is reversed, displacing the first-generated workpiece axis from the subspindle axis, and a second diameter, eccentric to the first diameter, is formed by the cutting tool unit in a second operation.

摘要： A machine guard has an opening with a detachable door; i.e., sliding tracks and hinges are not used for door support. When an outside loader arm and its part grippers move to the door, the door is unlatched from the guard and attached to the arm. The arm and grippers then move through the opening, taking the door away from the opening.

摘要： A centrifugal particulates filter has inlet and outlet ports for coolant flow, and a flushing port for handling partiulates removed from the main coolant stream. The flushing port is connected to a coiled capillary tube to maintain a constant drain flow of particulates and coolant, the coolant being recycled to the coolant tank.

摘要： Spaced headstock shafts are supported in common headstock walls such that their ends are inaccessible. The shafts are connected by an active timing belt. A spare timing belt is assembled around, but held out of contact with the shafts. At replacement time, the worn active belt is cut and removed and the spare belt is axially moved into its place. The drive may also include a belt tensioner.

摘要： A strainer cup strains a flow of particle-bearing fluid. When blocked, unstrained fluid overflows the cup spilling into a chamber. A switch detects a level of fluid and signals a blocked strainer cup condition, as the chamber drains off the unstrained fluid.
