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 fibre-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 fine 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, which is a result of the cutting edge being made of the hardest known material. In addition, the PCD inserts provide short 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.
