With trochoidal milling strategies offering the benefits of reduced cycle times and tooling consumption — along with improved productivity, material removal rates and component quality — Tamworth-based Industrial Tooling Corporation Ltd (ITC — www.itc-ltd.co.uk) has once again extended its already substantial trochoidal milling portfolio.

Complementing the company’s four- and five-flute trochoidal ranges are additions to the six-flute range with the introduction of the new 6051-series cutters.

These have been developed specifically for the machining of steel and ‘exotic’ material types; they feature a long flute length for reaching into pockets and difficult-to-reach surfaces.

Moreover, the geometry of the 6051 cutters has been designed to offer end users a robust and stable platform that “instils confidence when undertaking extended-length machining”.

The 6051-series cutters have a centre-cutting geometry with ‘harmonic fluting’ to maximise material removal rates and swarf evacuation while minimising vibration, thereby enhancing surface finish and tool life.

This rigidity and performance is further enhanced by a shallow ‘chip gullet’ that ensures ‘exceptional core strength’ for high material removal rates and stability.

Complementing this are polished flutes and a ‘Cupro’ coating to optimise chip evacuation.

These 6051-series tools are offered with square end geometry for 90deg machining in corners; and to further enhance the strength and longevity of these end mills, they are available with corner radii of 0.25. 0.5, 0.75 or 1mm.

These six-flute tools are available with diameters of 6, 8, 10, 12, 16 and 20mm, with lengths of cut from 18mm on the 6mm-diameter tool up to 60mm on the 20mm-diameter one.

Overall tool lengths range from 75 to 150mm, depending on the diameter selected.
