PCD Milling Cutters Reduce Cutting Forces and Vibration

Walter USA LLC offers the MP060, MP160 and MP260 milling cutters with brazed PCD cutting edges for machining aluminum, aluminum-silicon alloys, magnesium alloys, plastics and fiber composite materials (ISO N and ISO O, or other material groups). The new tools are for automotive, aerospace, electronics and general mechanical engineering applications with the finest surface quality specifications.

The MP060 face milling cutter has from 10 to 22 teeth (z = 10-22) and is available with a diameter from 40 to 125 mm. It is suitable for roughing and finishing large surfaces and flat shoulders. It features threaded holes that accept balancing screws.

The MP160 shoulder and slot milling cutter is available with either a cylindrical shank or ScrewFit adaptation and is available with a diameter from 16 to 40 mm. The tool has three or four teeth (z = 3-4), and is suitable for ramping, helical drilling and full slotting.

The MP260 routing cutter is also available with cylindrical shank or ScrewFit adaption and is available with a diameter from 4 to 20 mm. It has two or three teeth (z = 2-3) and is suitable for plunging, full slotting and milling small flat surfaces.

All three PCD milling cutters are equipped with an internal coolant supply and can be used with emulsion or minimum quantity lubrication (MQL). Their service life is 20 to 200 times longer than that of solid carbide cutters, which is primarily the result of being made with Walter’s wear-resistant poly-crystalline diamond WDN20 grade, as well as because of reduced cutting forces and a low-vibration microgeometry.

In addition to providing cost-effective precise machining, the MP060, MP160 and MP260 PCD milling cutters require fewer tool changes than carbide cutters due to their longer service life. Tools at least 6 mm in diameter can be reconditioned to extend the service life.
