25A axial grooving system with extended working range
Whereas the previous system with one-edged or two-edged indexable inserts achieved cutting widths of 2 to 4 mm, and a grooving depth of up to 18 mm from an external diameter of 15 mm, the further developed cartridge and round shank versions now allow for grooving diameters of 50 to 65 mm and from 65 to 80 mm with cutting widths of 3 and 4 mm.
The cartridges are designed for HORN‘s K220 standard cartridge interface and are therefore compatible with all basic holders for this system. Its internal coolant supply ensures efficient cooling that does not have a negative effect on chip flow. The tool holders can be equipped with carbide inserts of type 15A or 25A, with one or two cutting edges in carbide grade TH35 and TiAIN-coated. The .10 geometric shape for longchipping materials also ensures safe chip flow, even with large groove depths.
The single-edged insert also allows grooving along an interfering contour, such as a collar, making it suitable for universal use. As the dimensions of both cutting insert designs are identical, the single-edged inserts also fit into all holders of the 25A system.
