Floating and precision adjustable cutters for boring

Abstract:

A cutter assembly for a boring bar may include a cutter body, a cutter-element carrier, and an adjustment assembly having an adjustment element. The cutter-element carrier may be configured to be slidingly received in a channel in the cutter-body. The cutter-element carrier may have a first surface transverse to the first line. The adjustment element may have a second surface defining a position of the cutter-element carrier in the channel when the second surface is in contact with the first surface. The adjustment element may be movable along a second line transverse to the first surface for adjusting the position of the cutter-element carrier in the channel. The cutter body may include first and second recess portions. First and second insert portions may be inserted into the first and second recess portions, respectively, and may define float travel-limits for the cutter body.
