With the new double-edged WT26 indexable inserts and the compatible tool-holder system, Walter says it offers a solution that can optimise the machining of small parts on Swiss-type sliding-head turning centres. According to the company, the dovetail shape of the insert clamp absorbs lateral forces to elevate stability, process reliability and accuracy. The clamp system and the large contact surface in the insert seat maximise rigidity, counteracting any vibration of the bar material.

Another special feature is the possibility of performing operations on both sides. This design concept is credit to a clamping screw that features a Torx screw drive on both the head side and threaded side, facilitating operation from the side of the counter-spindle on right and left-hand tools. Users can index the inserts quickly without removing the tool holder, reducing non-productive time.

The tangentially mounted WT26 indexable inserts are precision-ground and boast sharp cutting edges specifically for turning small precision parts. Furthermore, the periphery-ground chip-breaker geometries are available in DG8 and VG8 designations, which Walter says facilitates optimal machining results even at feed rates as low as 0.03 mm.

Walter’s WT26 indexable inserts come in seven different versions, covering all turning operations. This selection includes everything from basic recesses and external threads, to reverse turning with specially developed chip breakers.

The new WSM23X cutting tool material is suitable for machining steel, stainless steel and lead-free brass. In addition, the uncoated WN23 grade suits aluminium and non-ferrous metals. Operators can use the inserts in any WT26 tool holder, regardless of the system.
