With the MP060, MP160 and MP260 face, shoulder and slot drill milling cutters with brazed PCD cutting edges, Walter presents a range of products for machining aluminium, Al-Si alloys, magnesium and magnesium alloys, as well as for plastics and fibre composite materials. The MP060 face milling cutter with a high number of teeth (z) between 10 and 22, and with diameters from 40 mm, can be used for roughing and finishing large surfaces and flat shoulders. The MP160 (z = 3–4) and MP260 (z = 2–3) shoulder and slot milling cutters, with either parallel shank or ScrewFit adaption and diameters of 16–40 mm/4–20 mm respectively, are suitable for smaller flat surfaces, for plunging (MP260) and full slotting, as well as (limited to MP160) ramping, drilling and re-drilling work. All three milling cutters are equipped with internal coolant supply and can be used with emulsions and minimum quantity lubrication.
The milling cutters offer decisive advantages, primarily with respect to the service life, surface quality and efficiency. Their service life, which is significantly longer than that of solid carbide tools, combined with the internal coolant supply, is primarily the result of the wear-resistant WDN20 Walter grade, as well as reduced cutting forces and low-vibration microgeometry. Precise machining enables users to produce high-quality surface finishes. The milling cutters are cost-effective due to their high cutting speeds and resulting shorter machining times. In addition, relatively low cutting material costs, fewer tool changes due to the longer service life, and the fact that the milling cutters can be reconditioned (diameters of 6 mm or more) also increase the tools' service life. From Walter's perspective, these milling cutters offer the greatest potential in the general mechanical engineering sector and in the automotive industry, for instance when milling over small surfaces on aluminium components, as well as for ISO N components in the electronics industry, such as those made of magnesium.
