Walter AG is using its M4258 porcupine milling cutter for shoulder and slot milling to combine the benefits of a milling body with those of indexable inserts.
The modular milling cutter has a replaceable front piece. This allows the part of the tool body that typically becomes worn most quickly to be replaced, namely the front and face. These are subject to the most rapid wear because milling cutters are rarely used over their whole length and bending forces are greatest here. The positive-locking connected interfaces in the front piece ensure that precision is maintained. Good chip clearance and internal cooling ensure high process reliability and safe chip evacuation. Walter Capto™ C6 and C8 have been chosen as interfaces to the machine. These are tried and tested, especially in highly universal applications and with any kind of modular machining tool.
While the indexable inserts used continue the trend in saving tool costs, the M4258 is equipped with M4000 system inserts. Square and rhombic with four or two cutting edges, it can be used not only in porcupine milling cutters, but also in face, shoulder, chamfer and T-slot milling cutters. Diverse geometries, such as the D51 anti-vibration geometry, allow the milling cutter to be used in difficult conditions. Tiger·tec® Gold inserts are additionally available on request – these increase the tool life further. M4258 milling cutter and M4000 system inserts provide a solution which reduces storage and procurement costs, while simultaneously conserving resources. This is because the entire milling cutter, including body is manufactured with CO2 compensation. It is suitable for practically all materials, such as cast iron, steel, stainless steels and materials with difficult cutting properties. The modular porcupine milling cutter from Walter is available in diameters of 50–80 mm and is recommended for anyone machining with high material removal rates in unfavourable conditions.
