Abstract: A tool accessory used to apply different volumes of a cutting fluid to the tap under CNC control by causing the machine to undergo different pump cycles in which the rotational speed of the tool is increased above the tapping rotated and then quickly returned to the tapping rotation. The tool includes a tapping head, a reservoir filled with cutting fluid, a centrifugal force-reactive pump and at least two discharge nozzles. The pump includes a plurality of biased piston springs that are forced outward and store centripetal force when the tool is rotated at speeds above normal tapping speed. When the rotational speed of the tool is reduced, the piston springs overcome the centrifugal forces and force cutting fluid through the discharge nozzles. The volume of cutting fluid discharged is controlled by adjusting the viscosity of the cutting fluid, the tool's maximum speed, by using different size discharge nozzles, and by using different pump cycles.

Abstract: A HSK spindle tension testing kit for measuring the force exerted by the drawbar assembly on the spindle on a CNC machine. The kit includes an upper frame member, a clevis, a pressure jack, a guide piece, a grip-housing, and a transfer rod. The guide piece is aligned over the grip-housing which is placed inside the front cavity on a HSK spindle. During operation, the drawbar assembly engages the grip housing. The transfer rod is threadingly connected at one end to the grip-housing, extends through the guide piece and connects to the shank on the upper frame member to hold the pieces together. During use, the pressure jack and clevis are then used to apply a pulling force on the transfer rod and to test the amount of force exerted by the drawbar assembly on the grip-housing.

Abstract: A spindle tension testing kit designed to allow mill operators to quickly and easily determine the gripping or holding force of the coupler and drawbar assembly on a spindle against the tool holder used with a milling or other machine using this method of tool retention. In one embodiment, the kit includes a tool holder, an upper frame member, a transfer rod, a clevis member, and a modified pull stud, and a hydraulic piston. The upper frame member threadingly connects to the transfer rod that is longitudinally extended into the central bore formed in the tool holder. The frame member includes a central opening with a lower horizontal member designed to receive a clevis member. The clevis member is a U-shaped member disposed in an inverted, longitudinally aligned position over the lower horizontal member on the frame member so that its legs are adjacent to the top surface of the tool holder when assembled.
