UNITED GRINDING recently launched Fine Pulse Technology that significantly boosts surface and cutting edge quality and, therefore, overall resulting tool performance reliability in the production of polycrystalline diamond (PCD) metalworking tools. All UNITED GRINDING's WALTER erosion machines, such as those in the HELITRONIC line, will offer the new technology.

Eroding systems with Fine Pulse Technology produce tools with smoother, more perfect exteriors and cutting edges along with super-fine finishes that match the level of visible shine generally reserved for polished tools. Such results eliminate regrinding and polishing steps during cutting tool production to help increase output. Fine Pulse Technology finely finishes tools made from the most common PCD types with 10 μm grain size and from coarse-grained types as well.

As the world leader in tool grinding technologies, WALTER continuously develops new erosion methods to meet heightened requirements for the surface quality, tool life and cost-effective production of PCD tools. To create Fine Pulse Technology, WALTER completely redesigned the erosion generator, improved eroding software and optimized a host of machine elements.
