Importantly, 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. Inserts can be used in a neutral position or as left-hand or right-hand configurations.
By adding the new system to complete its triple-edge insert range, Horn is responding to customer solution requests for Swiss-type lathes and other smaller turning machines, in particular for applications where space is at a premium.
The maximum groove depth using 32T is 4 mm with a width of 2 mm or 2.5 mm. 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 10 by 10 mm or 12 by 12 mm cross section. Each version features internal coolant supply.
