Titanium components are often not only hard but also poor conductors of heat, making them difficult to machine. Cutting rates of up to 95% pose an additional challenge.
The new Walter BLAXX M3255 porcupine milling cutter achieves outstanding results in this regard thanks to a completely new design. A special front insert with an axial limit stop, combined with the new geometry of the tangentially arranged indexable inserts, allows for an "overlapping" arrangement, with more inserts per row of teeth and more rows of teeth per milling cutter. The "continuous" cutting edge this creates cuts into the workpiece virtually seamlessly. Another new feature is that each of the indexable inserts is supplied individually with coolant. Coupled with the large chip clearances resulting from the new insert arrangement, this optimises cooling and chip evacuation. This is particularly advantageous when it comes to slot milling, which is why the M3255 can also perform slot milling operations with larger diameters.
The Walter BLAXX M3255 is equally well suited to shoulder milling, contour milling and pocket milling titanium alloys. The L65T geometry is available in two different grades: WSM45X for high machining volume and long tool life, and WSP45S for a high level of process reliability, even in difficult conditions. Their sharp cutting edges guarantee very high machining volumes despite only using low cutting forces. The Walter BLAXX M3255 is available in diameters 50-80 mm. The main benefits for the user are the short machining times, an incredible metal removal rate and a high level of process reliability.
