PRODUCTS 46 PRODUCTION MACHINING :: NOVEMBER 2016 Diamond Burnishing Tools Produce a Mirror-Like Finish Diamond burnishing tools from Elliott Tool Technology produce an ultra- smooth, mirror-like surface finish on linear surfaces in a single pass, the company says. This cost-effective, easy-to-use tooling from Monaghan Tooling Group improves surface irregularities and tool marks, producing optimum surface finishes of 4-8 Ra, the company says. This technique can eliminate secondary processes such as grinding, honing and polishing by automating those processes in the primary CNC machine. Doing so is said to save setup, processing time and labor costs and also enhances machinery use and shopfloor productivity, according to the company. Diamond burnishing is especially useful for a variety of parts and ductile metals less than Rc 40, including steel, stainless steel, aluminum and cast iron. A cast iron shaft, which started at a pre-burnished 67-Ra micron surface finish yielded a 10-Ra micron finish with a 0.0005" material com- pression in a single pass at 750 sfm. This was particularly helpful as the abrasive material was wearing inserts rapidly and attaining the desired part print was difficult. These diamond tools are designed to increase surface hardness through the cold-working process and compressive forces, and they increase metal's resistance to fatigue and failure at stress points while producing a dense and uniform surface. They are available in inch and metric slim-line, square, offset, on-center, stick and boring bar styles. With cycle times that are measured in seconds rather than minutes, dia- mond burnishing allows companies to achieve a consistent mirror-like finish and replace hand polishing. Economical, long-lasting and replaceable wear parts are said to reduce the total cost throughout the life of the tool. Wear parts are easy to replace, with common tooling available from stock. Their operation and maintenance requires minimal training, the company says. :: Monaghan Tooling Group, 800-732-4565 monaghantooling.com VEX-S VEX-P COMBI Combination Drilling www.HeuleTool.com For Product Videos & Brochures Visit High performance, time saving, drilling with front and back chamfering Starting at 5mm/.197"
