WITH its new shoulder milling cutter F 4041, Walter-Speedmax has for the first time developed a shoulder milling cutter with rhombic indexable inserts that provide four positive cutting edges with an approach angle Kappa of precisely 90° and can improve productivity by up to 100 per cent.
The F 4041 cutter is included in the new range of Xtra-tec tools.
The Tubingen-based tool manufacturer has designed indexable inserts that feature an extreme spiral that is applied four times.
Benefits include: the costs per cutting edge are considerably reduced; the approach angle Kappa of precisely 90° prevents the generation of steps - therefore, shoulders do not need to be finished.
In addition, the positive cutting angle ensures soft cutting action and permits high feed rates at low power consumption. The negative basic shape of insert also ensures maximum process security.
The cutters are available within the range of diameters of 40 to 160mm, and cutting depth of 15mm. They are recommended for machining steel, cast iron and non-ferrous metals.
Users can choose between the versatile ScrewFit system or the standardised bore fixture.
