Diamond Burnishing Tools from Monaghan Tooling Group (Dayton, OH) produce a smooth, mirror-like surface finish on linear surfaces in a single pass.
This tooling by Elliott Tool Technology improves surface irregularities and tool marks, producing optimum surface finishes of 4-8 Ra. This technique can eliminate secondary processes such as grinding, honing and polishing by automating those processes in the primary CNC machine.
Diamond burnishing is ideal for a wide variety of parts and ductile metals under Rc40, including steel, stainless steel, aluminum and cast iron. A cast iron shaft which started at a pre-burnished 67Ra microinch surface finish yielded a 10 Ra microinch finish with a 0.0005-inch material compression in a single pass at 750 SFM.
