ABSTRACT:
A side trimmer made from hardened steel has an inner diameter with a keyway, an outer diameter, and two faces. A recess is machined in the faces to a radius greater than the keyway root. The recesses enable the faces to be hard faced with a ceramic tool without the tool being destroyed by interrupted cuts at the keyway. At least one face is formed with an annular groove that separates the faces into inner and outer faces. The outer face cooperates with the outer face of a second side trimmer to form a nip that trims a moving coil. When the outer faces have worn, they are resharpened by hard turning with a ceramic tool.
