Walter enhances standard range of PCD milling cutters for non-ferrous materials

Walter is enhancing its expertise in the machining of non-ferrous metals with the company’s new range of PCD milling cutters. As most PCD tools are often custom solutions, Walter is expanding its standard ISO N range with the solid MP271 and MP470 milling cutters.

The three-edged MP271 drill slot cutter, available in 16 to 25mm diameter, features a segmented cutting edge length of 30mm and a centre cutting edge, ensuring its suitability for deep depths of cut. This makes the MP271 the preferred choice for operations such as trimming, as its differential pitch geometry minimises vibration.

Complementing the MP271 is the double-edged MP470 spherical cutter, available in diameters of 4, 6, 8, 10, 12 and 16mm. This two-flute ball-nosed end mill is designed for creating and finishing free-form surfaces. Depending upon the diameter selected, the MP470 ball-nosed end mill has a cutting length from 4 to 14mm with an overall length of 55 to 80mm.

Both PCD milling cutters have been specifically developed for ISO N materials such as aluminium, Al-Si alloys, magnesium alloys, copper alloys and fibre composites. Utilising the company’s WDN20 PCD grade, Walter says the new arrivals can extend tool life and machining performance.

Notably, the brazed PCD cutting edges are also suitable for reconditioning. Combining this opportunity to recondition with the extension of tool life enhances the tools’ sustainability. Furthermore, it reduces the cost of the cutting tools. The specific properties make these new PCD milling cutters particularly appealing for manufacturers machining aluminium in general engineering applications, as well as in the automotive and aerospace industries.
