New insert size maximises productivity and process reliability

New insert size maximises productivity and process reliabilityBromsgrove-based Walter GB Ltd, is continuing to develop the Xtra tec XT family and is bringing tools for the 12mm insert size to the market to accompany those already available for the 9mm insert size.

Both insert sizes can be used in milling cutters with different approach angles: With an approach angle of 45deg and thanks to its higher number of teeth, the M5009 (diameter 25–160mm) is ideal for reduced depths of cut (5 or 6.5mm) and suitable for reduced machining conditions, for example to increase productivity in mass production.

The M5012 (diameter 32–160mm) has a steep approach angle of 88deg, making it possible to work with larger machining conditions and depths of cut (8 or 10mm) and is less affected by interference contours.

Both face milling cutter families are designed for high feed rates per tooth at maximum process reliability. The tools with a medium or large pitch for insert size 12 are designed with carbide shims. These increase the tool life and protect the milling body against damage in the event of an insert fracture. Inclined clamping screws make access easier and shorten the time required to replace inserts.

Both are suitable for both roughing steel and cast iron materials, stainless steels, difficult-to-cut materials and non-ferrous metals, as well as for roughing and finishing work with wiper inserts.

They can be equipped with three types of indexable inserts: Square, eight-edge system inserts for different approach angles, double-sided indexable inserts with suitable facet (also with eight cutting edges; either fully ground or sintered circumference) and with double-sided wiper indexable inserts with two cutting edges.

An additional factor is the special aluminium geometry. Combined with the Walter Tiger tec cutting tool materials, this increases tool life and cost efficiency. Walter sees the automotive industry, the aerospace industry and general mechanical engineering as classic fields of application. In addition, the positive, soft cutting action, even on low-performance machines, guarantees good results.
