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.

- grinding
grinding
Machining operation in which material is removed from the workpiece by a powered abrasive wheel, stone, belt, paste, sheet, compound, slurry, etc. Takes various forms: surface grinding (creates flat and/or squared surfaces); cylindrical grinding (for external cylindrical and tapered shapes, fillets, undercuts, etc.); centerless grinding; chamfering; thread and form grinding; tool and cutter grinding; offhand grinding; lapping and polishing (grinding with extremely fine grits to create ultrasmooth surfaces); honing; and disc grinding.
- metalworking
metalworking
Any manufacturing process in which metal is processed or machined such that the workpiece is given a new shape. Broadly defined, the term includes processes such as design and layout, heat-treating, material handling and inspection.
- polishing
polishing
Abrasive process that improves surface finish and blends contours. Abrasive particles attached to a flexible backing abrade the workpiece.
- polycrystalline diamond ( PCD)
polycrystalline diamond ( PCD)
Cutting tool material consisting of natural or synthetic diamond crystals bonded together under high pressure at elevated temperatures. PCD is available as a tip brazed to a carbide insert carrier. Used for machining nonferrous alloys and nonmetallic materials at high cutting speeds.
- polycrystalline diamond ( PCD)2
polycrystalline diamond ( PCD)
Cutting tool material consisting of natural or synthetic diamond crystals bonded together under high pressure at elevated temperatures. PCD is available as a tip brazed to a carbide insert carrier. Used for machining nonferrous alloys and nonmetallic materials at high cutting speeds.
