Sandvik Coromant offers a number of cutting tools, including drills, bores and millers, designed to increase productivity and component quality for companies manufacturing wind turbines.

The Corodrill 880 is an indexable insert drill that is said to allow improved productivity in hole-making and offer cost-saving potential to wind sector manufacturers due to the large number of short holes drilled in components including connector rings, hubs and rotor blades.

Corodrill 880 incorporates Sandvik Coromant’s Step Technology into its centre insert to facilitate smooth entry into the workpiece through balanced cutting forces, enabling feed-rate increases of up to 100 per cent.

Drilling is also a key operation when producing main shafts.

Tools such as Corodrill 800 and T-Max are indexable drills that are said to offer good deep-hole straightness and surface finish.

Sandvik Coromant’s Corobore 825 offers good performance in the finishing of holes with tight tolerances and surface finish requirements.

It provides the potential for stable and reliable performance when finishing wind industry parts such as planetary carriers and main frames.

Corobore 825 features a coupling design that integrates an elliptical interface to absorb tangential and radial forces.

To achieve maximum flexibility, Corobore 825 accommodates three cartridge sizes, each with its own slide extension.

The slide extensions are placed between the cartridge and cross-slide to allow for back boring and to extend the maximum diameter when push boring.

Moving to milling operations, Coromill 345 is described as an advanced tool concept that provides high-performance face cutting with both small and large depths of cut in steel, stainless steel and cast iron.

It is said to offer particular value in applications ranging from rough milling of raw forgings and castings through to finishing operations requiring extremely close tolerances.

Coromill 331 and Coromill 390 can offer optimised machining when performing operations such as the back facing of hubs or helical interpolation on planetary carriers.

Sandvik Coromant’s T-Max P concept features geometries designed purposely for effective chip breaking.

It allows metal removal at high feed in dry conditions, making it suitable for turning applications on wind energy parts such as connecting rings and planetary carriers.

The latter is typically manufactured from nodular cast iron, where T-Max P offers high wear resistance due to innovative substrate and coating technologies.
