The German tooling manufacturer Paul Horn GmbH
, which has a UK subsidiary in Ringwood, is expanding its 220 cartridge system to cover virtually all insert types in the company’s tool portfolio.
Horn says all cartridges can be clamped directly and quickly in universal holders, and that the system’s T-shaped interface offers a high level of precision when changing cartridges.
“In addition, the T-shape ensures a stable interface between the holder and the cartridge — and all variants feature an internal coolant supply.
“The coolant jet is emitted directly from the clamping finger and support, to ensure that cooling is targeted at the cutting zone during use. The upper opening of the internal coolant supply can be shut off as required.”
Horn offers radial grooving cartridges for the 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, which support a large number of groove widths, groove depths and parting-off operations, as well as substrates and coatings tailored to specific materials.
A variety of machine interfaces are accommodated, and Horn offers the holders in square or round shank, as well as TS, HSK and polygon interface versions.
Horn says the modularity of the tool systems plays a vital role in enabling the flexible and productive use of tools, particularly in the case of small and medium-size batches. “The aim is to reduce set-up times significantly during tool change while making the machine more efficient.
“The system can be used on single-spindle lathes and multi-spindle autos alike, and the process of changing the cartridges is both user-friendly and precise.”
