CoroCut QI offers optimal internal grooving and face grooving in small diameters.
Sandvik Coromant has launched CoroCut QI, a range of internal and face grooving inserts designed for smaller diameters. "Optimized to enable a lighter cutting action and reduced cutting forces, CoroCut QI offers high process security, reliable grooving operations and precise chip evacuation, resulting in high surface quality grooves," said a company spokesperson.
The addition of CoroCut QI completes the CoroCut Q platform, which already consists of CoroCut QD for parting off and CoroCut QF for secure face grooving. CoroCut QI provides a comprehensive selection of optimized tools for numerous parting and grooving applications and is designed specifically for smaller diameters. All inserts fit internal and face grooving toolholders, making it easier for users to select the right tool.
CoroCut QI is divided into internal grooving and face grooving application areas, and is an upgrade of the T-max Q-Cut 151.3 program. The improved design allows for greater chip control, a 10% productivity increase, 20% improved tool life aided by tighter edge-rounding tolerances and internal coolant for internal and face grooving tools, according to the company.
Key features of the CoroCut QI include an optimized tip seat angle for lighter cutting action and cutting forces that aid vibration-free machining, and a rail insert seat for a stable and precise insert position ensuring minimal insert movement. Screw-clamped toolholders offer stability and high process security, and inserts with high edge line quality increase tool life and surface quality.
"Grooving can be a difficult technique to master," said Angélica González, Product Manager of the CoroCut Q platform at Sandvik Coromant. "Long overhangs, difficult chip evacuation and stuck chips are frequent problems when machining internal and face grooves. CoroCut QI has been developed to tackle these challenges to help achieve optimal results. Besides this, most CoroCut QI tools have internal coolant channels that deliver coolant directly to the cutting zone to enable efficient chip evacuation with minimum damage to the surface."
González continued, "The smaller the groove, the harder it is to machine. To combat this issue, CoroCut QI inserts are specifically designed for small diameters that require great precision. For example, the minimum hole diameter for internal grooving is between 12 mm and 60 mm with a cutting depth of 2 mm and 11 mm. Face grooving inserts can be used in a first cut diameter between 16 mm and 102 mm, with a cutting depth of 5.5 mm to 20 mm."
The insert geometries include -GF, a ground sharp insert for internal grooving, -TF with direct pressed geometry for face grooving and internal grooving and turning, and -RM, ideal for nonlinear turning such as internal and face profiling.
"CoroCut QI is the upgrade to our previous grooving system," added González. "In fact, performance tests compared with competing tools have demonstrated better process security and chip evacuation for a higher quality surface finish."
