A Unique Tangential Single-Ended Insert for Parting
ISCAR is introducing a new, single-ended insert for parting, with a revolutionary clamping method (patent pending).
• Very rigid clamping in a tangentially oriented pocket. Increases pocket life by 3 times more than any other SELF-GRIP mechanism.
• Enables machining at high feed rates and provides excellent straightness and surface finish.
• Provides a solution to the problem of inserts being pulled out during retraction. Has a solid stopper, unlike the friction retaining force in the current systems. (Especially important on machines with a bar feeder or sub-spindles.)
• In the SELF-GRIP system the machining forces are exerted on a very short stopper, while in the TANG-GRIP system, machining forces are supported by a long and rigid rear wall. Pocket wear, which occurs during machining and insert indexing in the SELF-GRIP system, causes a reduction in the clamping force. This does not happen with the new TANG-GRIP system.
• The TANG-GRIP system provides very accurate grooving repeatability.
• The combination of tangential clamping and free chip flow results in improved tool and pocket life.
• Offers a free, unobstructed chip flow. This is very important in deep grooving, since there is no upper jaw to interfere as in the other clamping systems.
• Wear of the upper jaw of the conventional self clamping systems reduces the clamping force, while in the new system there is no effect on the clamping force. The flexible jaw is protected by the insert.
The TAG inserts are available with the familiar J- and C-type chipformers, with neutral and angular frontal cutting edges.
The new tools are equipped with a user-friendly clamping and extracting device.
The introduction of this new family will include blades and inserts in 3-4 mm widths in IC928 and the new IC908 AL-TEC grades. More sizes will follow. The blades are in standard sizes which fit ISCAR's blocks. They have a ruler engraved on them to assist in the adjustment of the blade's overhang.
