One or more embodiments of the invention enable a boring head to hold a boring tool at an adjustable offset from the axis of rotation in a balanced configuration while maintaining stability when rotating at high speed. The apparatus comprises a boring head body, a bar holder and dial screw, a boring bar, a balance shaft and a balance weight. The apparatus may be configured for a given diameter of operation through use of alternate size components and offsetting a balance weight to account for the components in use. One method of determining the various components to use comprises weighing the various components and creating a lookup table for quick lookup to enable machinists to quickly change the bore range on a machine.

Variable radius balanced boring head

A tool holder having two distinct phases, a first phase in which the tool is held in an interference fit with sufficient mechanical interaction between the two for the tool to be rotated at high speed and perform its intended purpose on a workpiece, and a second phase in which the tool is sufficiently released from the interference fit to be rapidly removed from the holder (as by an automated apparatus).

Binary machine tool holder

A tapered part measuring apparatus and method measures male and female tapered or conical parts. The apparatus and method use non-contact linear measurement technology for accurate and repeatable measurements, particularly of tapered parts with large deviations from their desired measurements. The tapered part suspends in non-contact position to the non-contact linear measurement probe on a true vertical axis to accurately assume the same position on replicate measurements.
