Horn expands cartridge tooling system for grooving and parting-off

German tool manufacturer Paul Horn GmbH - whose UK subsidiary is in Ringwood - is expanding its 220 cartridge system to cover virtually every grooving insert type in the tool portfolio.

All cartridges can be clamped directly and quickly in universal holders and the system’s T-shaped interface offers stability as well as a high level of precision when cartridges are exchanged.

All variants feature an interface between the holder and cartridge for an internal coolant supply. The jet emerges from the clamping finger and support, ensuring that coolant is targeted directly at the point of cutting. The upper opening of the coolant supply can be closed off with a screw if required.

Horn offers radial grooving cartridges for the following insert types: S100, S224, S229, S274, 34T, 312, S315, S316 plus the S64T six-edged grooving insert. For axial grooving, the cartridges are designed for the S25, S224 and S229 systems.

The versatile system supports a large number of groove widths, groove depths and parting-off operations, as well as substrates and coatings tailored to the material being machined. Users can select the holders according to the type of machine interface. Horn offers the holders in square or round shank as well as TS, HSK and polygon interface versions.

The modularity of the tool systems plays a vital role in enabling the flexible and productive use of tools when turning small and medium size batches of components. The aim is to reduce set-up times significantly during tool change, thereby making the lathe more efficient. The system can be used on all types of turning machine from single-spindle lathes to multi-spindle autos.
