NEW Grooving System for Swiss-Type Lathes and Cramped Spaces

HORN USA is proud to present the new 32T system for grooving and parting off on Swiss-type lathes and smaller fixed-head lathes. With a precision-sintered grooving insert and central clamping screw, the tool system offers high changeover accuracy for the cutting insert and direct entry into the insert seat of the tool carrier.

Additionally, 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 interfering contours and therefore permits both grooving on a collar and parting off directly at the spindle.

The grooving insert can be used as a neutral insert, and as both a left-hand and a right-hand insert.

The 32T system completes HORN USA's portfolio of triple-edge cutting inserts by offering a solution for smaller-scale applications. By adding the new system to its range, the tool manufacturer is responding to customer requests for a triple-edge cutting insert system for Swiss-type lathes and other smaller turning machines, in particular in applications where space is at a premium.

The precision-sintered 32T insert is secured to the holder with a central screw, removing the need for additional exterior clamping components that negatively affect chip flow.  Available in 2 and 2.5 mm (.079 and .098") widths with maximum depth of groove up to 4 mm (.157"). For grooving operations, the inserts are available with both straight and full-radius cutting edges.

HORN USA offers the indexable insert with a 15-degree chamfer for parting off. A cylindrically ground chip-breaker geometry makes for reliable chip removal.

The tool carrier is designed as a square shank measuring 10 x 10 mm or 12 x 12 mm. Both versions feature an internal coolant supply and are available in both left-hand and right-hand designs.
