초록 ▼

A process and apparatus for producing screw threads in hard material workpieces with a series of taps. The present invention employs a threaded bore formed in a bracket assembly to align and position multiple taps on a rotary machine. The taps are used in sequence to cut threads progressively deeper into a substrate. The present invention provides a method of aligning and orienting each progressive tap to begin its cut at the same initial starting point.

What is claimed is: 1. An arm for a tap alignment assembly comprising: a first threaded bore at a first end adapted to receive a tap that has a proximate end adapted to be held by a chuck and an opposite distal end having a threaded portion, wherein the first threaded bore receives the distal end of the tap, wherein the pitch and geometry of the threads of the first threaded bore are nearly identical to the internal thread desired to be formed in a workpiece, and a second bore at a second end for receiving a screw to fix the arm to a bracket. 2. The arm according to claim 1 wherein said arm is a cantilever arm, and said second bore is a smooth bore. 3. The arm according to claim 1 wherein said arm has a longitudinal axis and said first threaded bore is substantially perpendicular to said longitudinal axis. 4. The arm according to claim 1 wherein said first threaded bore is configured to have a bottom that has a geometry that conforms to said tap. 5. The arm according to claim 3 wherein said second bore is substantially perpendicular to said longitudinal axis. 6. The arm according to claim 1 wherein the first bore has a central longitudinal axis and the second bore has a central longitudinal axis, and the central longitudinal axis of the first bore is generally parallel to the central longitudinal axis of the second bore. 7. The arm according to claim 1 wherein the central longitudinal axis of the first bore is generally perpendicular to the longitudinal axis of the arm. 8. The arm according to claim 7 wherein the central longitudinal axis of the second bore is generally perpendicular to the longitudinal axis of the arm. 9. An arm for a tap alignment assembly wherein the tap has a proximate end adapted to be held by a chuck and an opposite distal end; the arm comprising: an elongate body containing a first bore at a first end thereof, the first bore being threaded, and the first bore being adapted to receive a distal end of a tap, wherein the pitch and geometry of the threads of the first threaded bore are nearly identical to the internal thread desired to be formed in a workpiece; and a second bore for receiving a screw to fix the arm to a bracket, and the second bore being smooth; and said arm has a longitudinal axis.
