Parting tools for small lathes

Horn has introduced a 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 indexing and direct entry into the seat of the tool carrier.

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 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 x 10 mm or 12 x 12 mm cross section. Each version features internal coolant supply.

Top grades for hard-part turning

Sandvik Coromant is releasing two grades for interrupted hard-turning operations: CB7125 and CB7135. Available immediately, the grades complete the company’s offer for hard turning, complementing the existing CB7105 and CB7115 grades.

The latest Sandvik Coromant grades provide the ability to perform medium-to-heavy interrupted cuts and remove the hardened layer (depth of cut up to 2 mm) in case- and induction-hardened steel components, typically for the automotive industry. Here, CB7125 and CB7135 offer longer and more consistent tool life, good levels of surface finish and consistent dimensional tolerances, says the company.
CB7125 and CB7135 are optimised for turning steel materials with a hardness of 58-62 HRc. Designed for medium intermittent cutting, CB7125 features a newly developed PVD coating that provides improved wear and fracture resistance for extended tool life. This grade, which contains medium CBN content, is suitable for the turning of shaft splines and shafts with chamfered oil holes or pockets. Further applications include the facing of gears, the hard-to-soft turning of crown wheels, and the removal of hardened layers.
The CB7135 grade is pitched at the longitudinal turning of gears and shafts with un-chamfered keyways or pockets, as well as CV joint components such as the inner/outer race and cage. Featuring a high CBN content, the grade is said to offer high fracture resistance and predictable machining results.
Available for T-Max P, CoroTurn 107 and CoroTurn TR tooling systems, the grades come in both positive and negative basic shapes, with various edge preparations.
