Horn has introduced a new version of its M310 milling system, which is now available with a cutter body having an internal coolant supply. It allows a higher level of precision when slot milling and cut-off milling, as no heat is transferred from the cutting zone into the component. For the same reason, the service life of the indexable inserts is extended, reducing tool costs. Additionally, the flushing action of the coolant combined with the geometry of the cutting edges prevents chip jamming in deep grooves.Two types of milling cutter are available. The screw-in milling cutter is offered in diameters from 50 mm to 63 mm with widths from 3 mm to 5 mm. As an arbour milling cutter, the body is available in diameters from 63 mm to 160 mm, the widths also being between 3 mm and 5 mm. The triangular S310 carbide inserts are mounted on both sides of the body to ensure efficient distribution of the cutting forces. Further geometries for processing various materials are being introduced, including one specifically for milling aluminium alloys.
As well as expanding the M310 system, Horn is rounding off its M101 and M383 disc milling cutter ranges. For the M101 tool, S101 inserts are available from stock with a width of 2.5 mm and new inserts with an 8-degree lead angle are available especially for slotting. For the M383 cutter, the range of bodies is being expanded to include diameters of 125 mm and 160 mm in addition to 100 mm and 200 mm.
