The DF tool series of drag finishing machines have been specially designed and enhanced for the processing of all types of cutting and forming tools, such as drills, end mills and taps, to name a few. Models are available to process from 18 to 60 tools per batch. Features include edge rounding of tungsten carbide cutting tools such as end mills and drills, which lead to longer tool life. Also, radii in the micron (0.001-mm) range can be achieved repeatably and accurately using the drag finishing process, the company says. Other features include smoothing and polishing of the flute areas of uncoated tools and complex flute geometries held by specially designed toolholders. The resultant smoother flute surfaces reduce built up edges, which in turn, allows for higher cutting speeds and increased tool life, the company says. Removal of droplets left on the tool surface by the coating process leads to better chip flow and increased tool life.
