SGIH 26/32 Self-Grip Parting & Grooving Blades

SGIH-26-3 SELF-GRIP PARTING OFF BLADE

TGFH 22MB-3L84 TOOLHOLDER

ISCAR Tang-Grip? has the following features:

? 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.
