LTJNR 93° Turning Tool Holder for Swiss Type Sliding-Head Lathes
With a 93° approach angle, the LTJNR turning tool holder covers what is probably the most widely used standard geometry in external turning – designed specifically for Swiss-type sliding-head lathes and machining with negative TN..1604 indexable inserts. The approach angle provides a balanced ratio between cutting-force distribution and free accessibility at shoulders and is therefore equally suited to longitudinal turning, facing and the machining of shoulders.
For the insert seat, the holder relies on lever clamping: instead of merely screwing the indexable insert down from above, the clamp lever actively pulls the insert into the pocket and against the lateral location faces. This produces a particularly rigid seat that suppresses micro-movements of the insert, especially during intensive shoulder machining. The head crank typical of sliding-head holders guides the chips in a controlled manner downward and away from the cutting zone – an important point in the cramped working space behind the guide bush, where chip wrapping can quickly lead to tool collision. The holder is equipped with standard TN..1604 indexable inserts such as TNMG or TNGG; six cutting edges per insert keep the tool cost per part low. The body of quenched and tempered tool steel provides the rigidity required for the fine, often long turned contours.
Anyone wanting to use a proven 93° geometry as an all-rounder on their sliding-head lathe will find a robust solution with good insert retention in the LTJNR holder. Indexable inserts are to be selected separately depending on the material and machining case.
