Profile: Bright Signet Machine Tools is engaged in the manufacturing of burnishing tools that are widely used in automobile components like connecting rod and cylinder. The roller burnishing tool consists of a series of tapered, highly polished and hardened rollers positioned in slots within a retaining cage. When a tool engages the work pieces, a hardened mandrel inversely to the taper of rollers, forces them against the surface of the work piece. Our roller burnishing tools are applied in bearing housings, connecting rods, bearing bushes, valve guides, bronze bushes, break cylinder and rotor stamping I.D. The roller's axes are set at a slight helix angle to the axis of the mandrel & work piece. This angular relationship causes the roller to move in a helical path around the work pieces surface, there by establishing a self feeding characteristic in the tool. The tool is constructed with the rollers axis parallel to the mandrel axis. The diamond burnishing tools complete within a selected diamond stem are suitable for carrying out the burnishing of turning/grinding surfaces on a lot of metals for obtaining a high level in finishing, from 0.05 to 0.20 pm. These are used in traditional and CNC lathes. These are suitable for workshops.
