  • Method for making a ball-nut and method for making a ball-screw
    Publication number: 20060053919
    Abstract: A method for making a ball-nut includes cutting a 360-degree closed-loop surface groove in the inner-circumferential wall portion of a ball-nut body using a whirling-type internal-diameter cutting machine. The closed-loop surface groove surrounds the longitudinal axis of the wall portion, is adapted for receiving a plurality of ball bearings, includes a helical-grooved portion substantially coaxially aligned with the longitudinal axis, and includes a crossover-grooved portion. A method for making a ball-screw includes cutting at least one 360-degree closed-loop surface groove in the outer-circumferential wall portion of a ball-screw body using a whirling-type external-diameter cutting machine. The closed-loop surface groove surrounds the longitudinal axis of the wall portion, is adapted for receiving a plurality of ball bearings, includes a helical-grooved portion substantially coaxially aligned with the longitudinal axis, and includes a cross-under-grooved portion.
