Back Chamfering Unit
Back Chamfering UnitThe BCU is an excellent tool for machining back chamfers from the front side of the component. The tool eliminates deflection by piloting in the component bore and is very repeatable because it actuates off of the face of the component. The standard cutters produce a 45 degree chamfer angle but special angles and radii are available on request.
