Walter has introduced four new Walter Lock (WL) geometries (FM2, MN2, RM4 and RP4) for the W1011 and W1211 copy turning systems. The stable WL interface enables high dimensional accuracy. Compared to standard V- or D-shaped ISO inserts, the inserts with a WL positive-engagement geometry feature 50% higher repeatability and lower tool costs thanks to having three cutting edges.

The FM2 geometry for finishing inserts has a sharp, fully ground circumference and a polished rake face. The geometry is for machining long, thin shafts with a low cutting pressure. It is available as a WL-VCG 35° and WL-RCG full radius version. The precision-ground, full-radius geometry is suitable for finishing stainless steel and super alloys, such as Inconel (ISO M and S material groups). The radii are 1.0, 1.5, 2.0, 2.5 and 3.0 mm.

The MN2 geometry is for indexable inserts that machine non-ferrous metals (ISO N material group), as well as being well-suited for superfinishing steel and stainless steel (ISO P and M material groups). It has a sharp, fully ground circumference cutting edge and polished rake face.

The RM4 geometry is a universal one for medium to rough machining. It features an extremely large chip breaking range that is ideal for turning stainless and super alloys (ISO M and S material groups). The RP4 geometry is ideal for medium to rough machining steel (ISO P material group). With a large chip breaking range, the geometry achieves a maximum cutting volume and enables long tool life. The stable roughing geometry enables high feed rates during copy turning.

With the addition of the new copy turning geometries, Walter now has a large offering for finishing, medium machining and roughing steel, stainless, cast iron, non-ferrous materials and super alloys. In addition to copy turning, the geometries are ideal for creating undercuts. The geometries can be used in both external (OD) and internal (ID) operations. Also, these are available for conventional turning lathes in size WL25 and Swiss-style machines in size WL17.
