CoroCut QD Concept for Grooving, Parting Off

October 01, 2014

The CoroCut QD concept for deep external grooving and parting off from Sandvik Coromant adds internal machining to the application range of these secure and reliable tools.

The CoroCut QD system now includes CoroTurn SL blades for deep grooves in internal machining. The modularity of the CoroTurn SL interface enables tool assemblies optimized for the specific application.

Internal grooving and parting off with long overhangs requires stability and tooling solutions that keep vibration to a minimum. CoroCut QD tools offer a stable clamping mechanism so that Silent Tools dampened boring bars can be used for vibration-free machining with long overhangs. For tube-shaped components, typically found in the oil and gas industry, this is welcome news enabling deep internal grooving to be machined with high process security.

As with the previously introduced CoroCut QD tools, the extended assortment features over- and under coolant. The over coolant easily handles chip control while the under coolant prolongs tool life further securing the machining process.

Related Glossary Terms

  • boring

    boring

    Enlarging a hole that already has been drilled or cored. Generally, it is an operation of truing the previously drilled hole with a single-point, lathe-type tool. Boring is essentially internal turning, in that usually a single-point cutting tool forms the internal shape. Some tools are available with two cutting edges to balance cutting forces.

  • coolant

    coolant

    Fluid that reduces temperature buildup at the tool/workpiece interface during machining. Normally takes the form of a liquid such as soluble or chemical mixtures (semisynthetic, synthetic) but can be pressurized air or other gas. Because of water’s ability to absorb great quantities of heat, it is widely used as a coolant and vehicle for various cutting compounds, with the water-to-compound ratio varying with the machining task. See cutting fluid; semisynthetic cutting fluid; soluble-oil cutting fluid; synthetic cutting fluid.

  • grooving

    grooving

    Machining grooves and shallow channels. Example: grooving ball-bearing raceways. Typically performed by tools that are capable of light cuts at high feed rates. Imparts high-quality finish.

  • parting

    parting

    When used in lathe or screw-machine operations, this process separates a completed part from chuck-held or collet-fed stock by means of a very narrow, flat-end cutting, or parting, tool.
