Grooving Tools

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 both internal and face grooving tools.

The added anti-vibration boring bars with C6 PCS machine side connection are suitable for up to 9xD boring depths, allowing direct assembly on the machine spindle or turret without the need for adapters. The boring bars can also minimize chatter as an integrated vibration damper suppresses unwanted vibrations during machining. 

The stable cutting edge enables feed rates in the range of f = 0.25-0.4 mm/rev, during grooving and parting-off, which results in reduced machining time across multiple operations. Reliable chip evacuation and control is ensured by a special chip formation. High feed rates require a stable machine  when grooving and parting-off, as well as secure clamping of the workpiece. Starting from a feed rate of 0.3 mm/rev (0.012”/rev), HORN recommends reducing the infeed for the first 3—4 mm (0.118”- 0.157”) during grooving and parting-off.

Two new grades have been added to TungCut to enhance its capacity in exotic materials: AH8005 insert grade, featuring strong coating adherence to its carbide substrate, eliminates notch wear that typically occurs during the machining of heat-resistant superalloys (HRSAs). New geometries include DGS inserts with 0.05 mm and 0.10 mm (.0002″ and .0004″) corner radii. These sharp cornered inserts allow lighter cutting and precision grooving/ parting-off of small parts advantageous in Swiss machine applications.

The CW100 grade expansion encompasses four new round insert formats with two geometries, E-01020 and T-01020, and four grooving insert geometries with widths of 3.175 mm (0.125”), 6.35 mm (0.25”) and 7.925 mm (0.312”). An aluminium-oxide-based grade with silicon-carbide whiskers (Al2O3-SiC), the SecomaxTM CW100 grade not only boosts machining speeds in advanced HRSA materials, but it ensures stable and predictable tool life for the lowest possible cost per part thanks to the silicon-carbide whiskers, which use optimized micro geometries for the utmost in ceramic wear resistance and strength.

This expansion includes two new TCL18 inserts with 1.75 mm and 2.5 mm thicknesses, expanding the existing line of 1.5 mm, 2.0 mm, and 3.0 mm inserts. The inserts are available in grade AH7025, a nano-multilayer PVD coating with high-aluminum content that provides hardness and adhesion to the grade for better process security during grooving operations.

Tangentially mounted grooving insert with a robust seating surface also ensures maximum stability. The insert and pocket design features an axial key stop for added stability against the side cutting (axial) forces. Precision cooling on the flank surface is offered as a standard feature for longer tool life. The chip breaker for the inserts is developed for heavy-duty machining to ensure short chips when cutting at maximum depth and when widening the grooves.
