Walter has introduced indexable inserts with brazed PCD (polycrystalline diamond) cutting edges for the Xtra·tec® XT M5130 shoulder milling cutter and most M4000 milling cutters, including the M4003 face milling cutter.
The PCD inserts are suitable for milling a variety of nonferrous workpiece materials, including aluminum, aluminum-silicon alloys, magnesium, magnesium-based alloys, plastics, and fiber-reinforced plastics. Prominent application areas include automotive, aerospace, and general mechanical engineering. Aviation in particular uses wrought alloys made of aluminum.
The new PCD inserts impart the finest surface finishes while shoulder, face, and slot milling. The tools enable precise machining with reduced cutting forces and minimal vibration tendencies. They have a low cost because of their extremely long tool life as a result of the cutting edge being made of the hardest known material. In addition, the PCD inserts provide the shortest machining times due to their ability to mill at high cutting speeds. The inserts can be used dry, with emulsion of MQL (minimum quantity lubrication).
The BCGT090304R-B85 WDN20 and BCGT120408R-B85 WDN20 positive rhombic inserts have one PCD cutting edge per insert and are for the Xtra·tec® XT M5130 shoulder milling cutter.
The SDGW09T304-A88 WDN20 and SDGW120408-A88 WDN20 positive square inserts are equipped with a single edgy PCD cutting edge. These system inserts with corner radius are for most M4000 milling cutters. The SDGW09T3AZR-A88 WDN20 positive square insert also has a single full edge PCD cutting edges and in some applications two corners may be used. It is designed specifically for the M4003 face milling cutter from the M4000 series.
