CoroMill 690 long edge cutter boosts titanium milling

Sandvik Coromant recently launched CoroMill 690, a long edge cutter for titanium milling, specifically suitable for aerospace components, such as the structural parts of airframes, wings and fuselages and landing gear. The amount of titanium in high-strength complex components is increasing and with this anticipated demand there is a critical need for improving machining efficiency.

CoroMill 690 is reported to be a high-productivity cutter, with cutting inserts with four cutting edges for economic 2D profile operations and optimised chip flutes to reduce chip jamming. Every insert pocket has a threaded coolant hole prepared for a nozzle for high-pressure coolant delivery to optimize chip evacuation. The chip evacuation is said to be highly appreciated when face and shoulder milling in cavities, in pockets or in full slots.

First choice applications include circular interpolation from a pre-drilled hole; edging and contouring and repeated square shoulder milling. The iLock rigid interface keeps the inserts rigid for consistently accurate milling. Axial support prevents insert breakages on the bottom row and chip jamming on the second row.

The CoroMill 690 long edge cutter is designed for use with the Coromant Capto modular tool holder system for stability and shank clearance, essential when machining long overhangs and reaches. The cutter is available in diameters of 50-100 mm, with two insert styles and closer pitch on large diameters for profiling.

The cutting inserts come in grades GC1030 or GC2040 in SL geometry, optimised for edging in titanium.
