Sandvik Coromant Launches CoroCut QI

(Sandvik Coromant: Sandviken, Sweden) -- Leader in metal cutting, 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 ensures high process security, reliable grooving operations, and precise chip evacuation, resulting in high surface quality grooves.

​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, designed specifically for smaller diameters. All inserts fit both internal and face grooving tool holders, 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-percent productivity increase, 20-percent improved tool life aided by tighter edge-rounding tolerances, and internal coolant for both internal and face grooving tools.

Key features of the CoroCut QI include:
• Optimized tip seat angle for lighter cutting action and cutting forces that aid vibration free machining
• A rail insert seat for a stable and precise insert position for minimal insert movement
• Screw clamped tool holders to ensure stability and high process security
• Inserts with high edge line quality to increase tool life and surface quality

“Grooving can be a difficult technique to master,” says 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.

“The smaller the groove, the harder it is to machine. To combat this difficulty, the 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 and 60 millimeters (mm) with a cutting depth of 2 and 11 millimeters. Face grooving inserts can be used in a first cut diameter between 16 and 102 mm, with a cutting depth of 5.5 to 20 mm.”

The insert geometries vary from -GF, a ground sharp insert for internal grooving, -TF with direct pressed geometry for face grooving and internal grooving and turning, plus -RM, ideal for nonlinear turning such as internal and face profiling.

“CoroCut QI is the upgrade from our previous grooving system,” continues González. “In fact, performance tests compared with competing tools have demonstrated better process security and chip evacuation for a higher quality surface finish.”
