New Emuge PCD And CBN End Mills Provide Up To 50 Times More Tool Life For Machining Difficult Materials.

NORTHBOROUGH, MA (June 26, 2003) - Emuge Corporation has introduced a full range of PCD and CBN End Mills that are pre-engineered and precision-manufactured for optimum performance in a variety of challenging cutting applications. The end mills are extremely durable and can provide 50 times more tool life than conventional carbide end mills.

CBN and PCD tools share a similar appearance and manufacturing process, however they are very different when considering their broad but divergent range of material applications.

PCD (Poly-Crystalline Diamond) is a matrix of randomly arranged diamond crystals, bonded to form an extremely hard film or wafer. These diamond wafers are cut to the desired form for the end mill's cutting edge via a wire EDM process. The cut shapes are then permanently affixed to precision manufactured carbide shanks through a sophisticated microwave-brazing technique, which forms a bond able to withstand temperatures to 1,100°F. Finally, the finished cutting edges are precision ground for added accuracy. The result is an extremely efficient tool for machining highly abrasive, non-ferrous materials, including graphite, high-silicon aluminum alloys, fiber-reinforced synthetics and copper alloys. These tools feature a "coolant-thru" design for efficient evacuation of dust and chips.

CBN (Cubic Boron Nitrate) wafers are formed through a sintering process, however the remaining tool manufacturing process is nearly identical to that of PCD tools. CBN is the hardest known substance next to diamond, and provides the cutting edge for long-lasting end mills, that proficiently machine hard steels to 66Rc, as well as hard castings, Inconel, Monel and Stellite.

Emuge PCD and CBN end mills are available from stock in ball nose, torus and flat end designs, in sizes from 3/16 to 1/2". Metric sizes are also available from 4 to 12mm.

Emuge, part of the 1,000+ employee German parent company Emuge-Werk Richard Glimpel KG, has been the product technology and performance leader in their field for over 75 years. The company manufactures an exhaustive line of taps, end mills, thread mills, holders and attachments, over 100,000 items sold through distributors worldwide.

North American Headquarters of Emuge are located in Northborough, MA USA, where applications solutions are managed and over 10,000 types of cutting tools and accessories are stocked for prompt shipment. Emuge also offers end user technical support through a network of in-the-field engineers with extensive tooling experience.
