Parting off along the Y axis
Paul Horn GmbH is offering new tool holder variants for the S100 system for parting off with the feed movement along the Y axis on turning/milling centres. This method enables a very effective grooving process with high cutting parameters, resulting in shorter machining times. Furthermore, there is the option to part off large diameters with a compact grooving tool holder as well as to part off with narrower groove widths.
Large moments of force occur, particularly when parting off workpieces of larger diameter. The space available in a machine often does not allow tools of large cross section to be used. With the new arrangement of the insert in the tool holder, the cutting forces are diverted to the main cross section of the grooving tool. This results in increased rigidity of the system as a whole for a given cross section of the grooving tool holder and allows higher feed rates to be used. The force in the longitudinal direction of the tool means narrower holders can achieve the same system rigidity. In modern generations of turning and milling centres, parting off with the new grooving tools causes the cutting force to be diverted in the direction of the spindle, meaning higher rigidity of the overall.
Horn is offering two holder variants for the parting off process. For the 842 and 845 modular grooving system, there is a cartridge with cutting widths of 3 mm (0.118") and 4 mm (0.157"). There is also a reinforced grooving blade, also with widths of 3 mm (0.118") and 4 mm (0.157"). Both variants are equipped with an internal coolant supply via the clamp and through the support. In addition, the S100 system provides an option for direct cooling through the cutting insert. The maximum groove depth (Tmax) is 60 mm (2.362"). The tried-and-tested grooving insert of the S100 system is used, which is available in various substrates and geometries.
