Face grooving system 25A
HORN has enhanced the cutting width and diameter of the tried-and-tested 25A axial grooving system with cartridges and round shanks. The cassettes are designed for the standard cassette interface K220 and are compatible with all applicable basic holders from HORN. Supplying internal coolant to the cutting point guarantees efficient cooling and boosts chip flow. Cartridges and boring bars were previously available from an external diameter of 15 mm, with a groove depth of up to 18 mm, and with one-edged or two-edged indexable inserts featuring cutting widths of 2 and 3 mm.
The system has now been expanded to include the 4 mm cutting width. This means that the system can achieve grooving depths of up to 20 mm. Both one-edged and two-edged straight-cutting or full-radius inserts are available now in the additional cutting widths. The .10. geometric shape also ensures reliable chip flow, even with significant slot depths. The cutting inserts have a "neutral" design and can therefore be used in left and right tool holders. They are made of TH35-grade carbide. Holders with diameter increments of 20 - 25 mm, 25 - 30 mm, 30 - 40 mm and 40 - 50 mm are provided for different slot external diameters.
