Horn USA recently expanded its circular milling system 304 with new thread milling inserts to perform in diameters of 8 mm (.315”).  THREAD MILLING SYSTEM 304 for small threads from 9 mm diameter. The precision tools are available as partial and full-profile versions for the production of threads by helical interpolation. Triple-edged inserts in the 304 system already exist for groove milling, finish boring, and chamfering. The new threading inserts spin on diameter 7.7 mm (.303”). Vibration dampening carbide shanks with integral through coolant ports make the system versatile and easy to use. The HORN circular milling system offers users a host of process advantages. It is fast, reliable, and produces good surface finishes. During the machining process, the tool plunges into the material either at an angle or almost horizontally and is then driven on a helical path. Threads can be manufactured at a highly reproduceable level of consistent quality. Circular interpolation has a wide range of applications and can be more economical when strategically applied when machining steel, special steels, titanium, and alloys. HORN’s circular milling tools are engineered for precision machining of grooves, threads, t-slots, profile milling and other circular interpolation processes.

 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. |
