Abstract
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.
