Walter is expanding the range of its proven Xtra·tec XT M5130 milling cutters with new milling cutter bodies for the cost-effective machining of large surfaces at a shallow depth of cut. This move responds to growing user requirements, especially for manufacturers wishing to machine large plain surfaces or stepped structures with minimal material removal. For these applications, Walter now delivers greater efficiency and productivity than ever before.
To achieve this, manufacturers require large tool diameters with a high number of teeth. Using the existing indexable insert sizes for depths of cut less than 16mm, Walter is expanding the available diameter range of the Xtra·tec XT milling cutter family from the previous 80mm with BC09 or BC12 cutting inserts to 100, 125 and 160mm. Cartridge tools extend this machining availability up to diameters of Ø315mm. The smaller cutting inserts allow for a higher number of teeth per diameter. This ensures faster and higher material removal rates on large surface areas, which subsequently reduces machining time.
Like all milling cutters in the Walter Xtra·tec XT range, the new variants also feature tried-and-tested design characteristics. This includes a 12% increase in the cross-section of the indexable insert around the insert bore, a 34% larger contact area for the insert, and a 40% stronger tooth back for enhanced stability and process reliability.
Thanks to the smaller and therefore more cost-effective inserts, the application saves not only machining time but also cutting tool material costs. This expanded portfolio is ideal for a wide range of applications, from face and shoulder milling, pocket milling, ramping, and circular interpolation milling. Furthermore, it is suitable for all materials in the ISO groups P, K, M, N and S.
