Rising production costs and a change in demand behavior require sustainability in metal cutting as well. As a leading manufacturer of precision tools, Walter has been addressing this issue intensively for a long time, among other things with milling cutters that not only produce components more economically and efficiently, but also sustainably. In doing so, Walter uses its entire field of activity: from the holder to the tool, inserts and cutting material to the milling strategy. Walter Xtra-tec XT milling cutters, for example, are characterized by three design features: Tooth backs with 40 percent more material increase body stability. A 34 percent larger contact surface of the inserts reduces the surface pressure between the insert and the insert seat. And the 12 percent larger cross-section promotes fracture resistance of the insert itself. All three features pay off in greater process reliability and performance, thereby reducing the consumption of operating resources, materials, time and energy..

Where milling is required with long overhangs, vibration-damping Walter Accure-tec holders can practically double the metal removal rate during milling - and reduce the use of resources in equal measure. Walter uses the example of Tiger-tec Gold to show how cutting materials optimize sustainability: The grades are highly wear-resistant and can often be used without coolant. As a result, users not only save machine and changeover times, but also coolant. The components require less cleaning, and the costly disposal of coolants and cleaning agents is reduced. Sustainability can also be optimized via the milling strategy: For example, the so-called "roll-in entry", i.e. the entry into the material in a 90° curve, as well as the "line-off" of the surface in spiral instead of parallel paths can save up to 30 percent machining time even with high-alloy steel and sustainably increase tool life.
