Dayton, Ohio – Carbide-Roll Burnishing Tools by Elliott Tool Technology produce a mirror-like surface finish while eliminating secondary operations, machining set-ups, and operator labor and cost. These carbide rolls from Monaghan Tooling Group improve surface irregularities and tool marks, producing optimum surface finishes of 4µ" to 20µ" (0.1 µm to 0.5µm). They are for both CNC turning centers and manual lathes, for OD and ID/OD burnishing applications. This proven technique can eliminate secondary processes such as grinding, honing, and polishing by automating those processes in the primary CNC machine. Doing so saves set-up and processing time and labor costs and also enhances machinery utilization and shop floor productivity.
Carbide rolls can be reconditioned several times, yielding economical tool life. Shank sizes are available from 1.5" to 2.0" (40mm to 50mm) in diameter, to process overall length of 9.5" (241.3mm) to 18" (457.2mm). Roll radius from 0.032" (0.787mm) to 0.093" (2.36mm) are available.
Spherical surface burnish tools, available in either 1" or 25mm square shank size, with a 0.125" radius, are for burnishing spherical and contoured surfaces to finishes as low as 2Ra to 8Ra microinch. Other sizes and spherical designs available.
Carbide roll burnishing is for a variety of parts and ductile metals under HRC40, including steel, stainless steel, aluminum, and cast iron.
Elliott carbide roll tools increase the surface hardness through the cold working process and compressive forces, and increase metal’s resistance to fatigue and failure at stress points while producing a dense and uniform surface.
