Grooving and parting off tool for smaller lathes

Horn has launched a new grooving and parting off system, 32T, for Swiss-type lathes and smaller fixed-head lathes. With a precision-sintered grooving insert and central clamping screw, the system offers easy insert indexability and direct entry into the seat of the tool carrier.

There is no need for clamping elements, which may have a detrimental effect on chip flow. The screw head of the clamping bolt does not introduce interference and therefore permits grooving and parting off directly at the spindle. The insert can be used in a neutral position or as a left-hand or a right-hand insert.

By adding the new system to complete its triple-edge insert range, the tool manufacturer is responding to customer requests for a solution for Swiss-type lathes and other smaller turning machines, in particular for applications where space is at a premium.

Maximum groove depth is four millimetres with a width of two or 2.5mm. For grooving, the inserts are available with both straight and full radius cutting edges. Horn offers the insert with a 15° chamfer for parting off. A cylindrically ground chip breaker geometry makes for reliable chip removal.

The tool carrier is designed as a square shank of 10x10mm or 12x12mm cross section. Each version features an internal coolant supply and is available in both left-hand and right-hand designs.
