STJNR 93° Turning Tool Holder for Swiss Type Sliding-Head Lathes
The STJNR turning tool holder with a 93° approach angle is an external turning holder for Swiss-type sliding-head lathes, where it primarily handles intensive external longitudinal turning, facing and shoulder machining with negative TN..1604 indexable inserts. The 93° approach is one of the most widely used standard geometries in external turning and provides a balanced ratio of cutting-force distribution and free contour accessibility – ideal for parts where a clean approach to a shoulder is required.
The holder body is made of high-strength, quenched and tempered tool steel and offers the rigidity needed to cleanly absorb the cutting forces on the workpiece supported by the guide bush. The indexable insert is fixed in the pocket by screw clamping, which allows a slim head area, a defined insert seat and quick indexing without a clamp. In combination with standard TN..1604 indexable inserts – for example TNMG or TNGG – six usable cutting edges per insert are available, keeping the tool cost per part correspondingly low. The shank is designed for the typical linear blocks and tool carriers on the sliding-head lathe.
Anyone wanting to equip their Swiss-type machine economically with the established TN..1604 system will find a proven all-round solution for external turning in the STJNR holder. The matching indexable inserts are selected separately depending on the material and machining task.
Scope of delivery: STJNR Swiss Type turning tool holder (without indexable insert) including screw and key.
