Sandvik Coromant’s expanded CoroCut program features larger insert seat sizes for wider grooves and a dedicated grade to enable higher performance in demanding parting and grooving operations. The M- and R-size inserts and holders increase the range of the parting and grooving program to cover from 0.590" for heavy-duty grooving, to 0.020" parting widths. The R size, the largest insert in the line, is designed for reliable performance in demanding grooving operations, the company says. The R-size insert achieves feed rates ranging to 0.020 ipr in various grades of steel, stainless steel and cast iron.
The M-size insert is said to provide high metal removal rates with quality chip control in heavy grooving and rough-forming applications. It is capable of producing groove widths ranging from 0.354" to 0.433" and allows chip forming at feed rates of as much as 0.016 ipr.
The parting and grooving system uses a patented rail and V-shaped insert design to boost precision in parting and grooving applications. With a secure clamping design, the system provides the rigidity and stability required for demanding applications, the company says.
To complement the additional insert sizes, the company also offers the GC1145 grade. With improved wear resistance and toughness properties, the grade enables increased time in the cut. According to the company, this can provide increased tool life and cutting speed in difficult parting-off operations in stainless steels as well as demanding parting and grooving in stainless steel, steel and heat-resistant super alloys.
