Groove machining on wind power components requires versatile, rigid tools for features on rings and shafts. The more recent developments in the area of parting and grooving tooling have targeted the heavy-duty end of machining, when added stability for longer reach is needed, a tougher cutting edge is necessary and when chip control is an issue.

Better Performance through Inserts

The CoroCut 1- and 2-edge system of grooving and parting tools is a benchmark concept which is continuously developing. This system is based on Rail and V-shaped designs, which with the length of insert gives exceptional stability. These factors make it possible to run at higher cutting data and to achieve better performance, security and results. A large variety of insert geometries and grades are available, dedicated to solve and optimize different operations, materials and feed areas, including turning, profiling and undercutting operations. Tailor Made inserts provide the solution for any application beyond the large standard range.

Combining Coro Technology

When combined with the CoroTurn SL70 system of adaptors and blades, grooving and associated operations can take on another dimension, eliminating the need for special tooling.

New larger CoroCut tool blocks, with an integrated Coromant Capto coupling, provide the ultimate in stability for long blade-overhang for machining deep grooves. Productivity does not have to be limited when deep grooves can be made efficiently in one pass. The inserts for these operations often need added strength through high edge-line toughness but with the wear resistance for a long tool life. GC1145 provides a new level of security with the possibility to increase cutting data and predict a long tool life at the more difficult end of grooving. This grade complements the broad, universal GC1125 grade where operations do not need the extreme level of toughness in the insert substrate.

New Solutions, Higher Performance

CoroCut R-size inserts with -GM geometry is a new solution for higher performance in heavy grooving. This is a development towards even more light-cutting inserts, requiring less power and being less vibration-prone. During the cutting action, chips are narrowed during formation, facilitating the removal of chips out of the groove as well as programming.
