TungCut Grade DGS

Tungaloy has added new grades and geometries to its TungCut line of grooving and parting-off tools. TungCut is a multifunctional grooving and parting-off line that offers a wide range of insert and toolholder variations to provide users with maximum performance in OD/ID grooving, face grooving, groove turning and parting operations. The company says the line features strong and reliable insert clamping to ensure minimum tool chatter, while providing maximum precision and tool life during heavy duty grooving such as groove turning.

Two new grades have been added to TungCut to enhance its capacity in exotic materials: The 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). The company says the grade boasts extraordinary wear resistance, providing long and predictable tool life during the machining of HRSAs. The other new grade is KS05F, a noncoated carbide grade which provides a good balance of wear resistance and fracture toughness, while eliminating built-up edge. The grade is well suited for productive groove machining of titanium alloys.

New geometries include DGS inserts with 0.05 and 0.10 mm (.0002" and .0004") corner radii. These sharp cornered inserts enable lighter cutting and precision grooving/parting off of small parts, which is advantageous in Swiss-type machine applications. In addition, a new STR insert features a full-radius, single-ended geometry for profiling. Unlike double-ended inserts, a single-ended STR eliminates concerns of the other cutting end interfering with the workpiece during machining, enabling close machining of deeper areas of the workpiece. A total of 85 items have been added to the TungCut line.

  • Swiss-Type Machines: More Than Just A Lathe

    CNC Swiss-Type machines have more capability built in than ever before. Many of these capabilites can be accessed using attachments that increase the throughput of the machine tool, improve the quality of the work coming off the machine and reduce or eliminate the need for secondary operations even for very complex workpieces.
