With its M4000 family, Walter has made huge advances towards achieving maximum cost effectiveness in milling. The M4000 system inserts can be used in a variety of tools, which means that they can be used for various types of milling operation.
They reduce not only the cost per cutting edge, but also the work and costs involved in procurement and storage requirement. With the new M4256, M4257 and M4258 porcupine milling cutters, Walter is now offering the same advantages for slot milling too.
The new milling cutters are incredibly versatile in terms of both the range of applications and the materials for which they can be used, such as steel, cast iron, stainless steels, and difficult-to-cut materials. They are available with Weldon shank, modular ScrewFit interface and bore adaption.
Their compact length and half-effective design with comparatively low cutting pressure allows for incredibly smooth operation. This reduces the tendency to oscillate and vibrate, making them the perfect problem solver in the face of unstable conditions. These benefits pay dividends particularly in combination with the D51 geometry insert. The generous chip clearance integral to these porcupine milling cutters makes for particularly effective chip evacuation, especially the flute design, where chips cannot fly out to the side. In addition, the milling cutters can be used for ramping, pocket milling, shoulder milling and circular interpolation.
These porcupine milling cutters are likely to be of interest to users operating in the general mechanical engineering sector, for example; these may be users who are already taking advantage of M4000 tools and indexable inserts, or they may be users who are looking for a cost-effective solution to constantly changing machining tasks.
