Perfect for today’s machine tools with powerful milling capabilities, the Double Quattromill 22 achieves its aggressiveness through a number of design features that elevate these tools above and beyond the competition. The first feature most machinists will notice is the Idun cutter body, an environmentally friendly alternative to the more common nickel coatings found on most cutter bodies. An exceptionally durable, corrosion-resistant tool steel, Idun adds considerable longevity to the cutter’s overall lifespan, and with a special post-treatment, the tool’s tough surface finish resists marring when handling or machining. The cutter bodies are available with diameters ranging from 3.0" to 12.5" (80 to 315 mm).
For additional durability and productivity, Seco designed the Idun body to include features like patented flute surface textures and flute spacing configuration for improved chip evacuation. Perhaps the most important aspect of the design, however, is the high-axial rake angles. Unlike other cutters with double-sided inserts, the Double Quattromill 22 produces lower cutting forces and requires less machine power consumption than the competition. The 45° lead angle version of the cutter provides the lowest cutting forces, while the 68° version can be used closer to walls or part fixtures while still providing greater depths of cut than a shoulder mill.
In addition to two lead angle options, manufacturers can also select Double Quattromill 22 bodies with fixed pockets in two different pitch options – standard pockets with differential pitch for good chip evacuation and reliable performance on less powerful machines, and close-pitch pockets for high-feed cutting with short-chipping materials – or cassette-style pockets for run-out reduction. All of the cutter bodies feature through-coolant designs.
The Double Quattromill 22’s inserts have also been designed from the ground up for highly aggressive face milling, with three free-cutting inserts available per rake angle type. The ME12 geometry is ideal for sticky materials like titanium and stainless steel, as well as operations that require operators to overcome horsepower limitations. The M12 geometry features a sharper edge suitable for some tool steels and superalloys in addition to stickier materials, providing good flexibility without raising cutting forces. Lastly, the M18 geometry has the best edge protection for abrasive-to-machine materials, beneficial when cutting parts from steels, tool steels and cast irons.
