HIGHLY SECURE CLAMPING
TOP LEVER
ISCAR is introducing an upgraded lever lock to
improve the clamping rigidity of the popular and
user-friendly insert clamping system.
The new design actually combines the advantage of
the current lever with the extra clamping rigidity of the
top clamp method.
The current lever pushes the insert against the
pocket, exerting perpendicular force to the cutting
force. This method sometimes fails during interrupted
cut or heavy load applications, which cause the rear
side of the insert to rise.
The top clamp mechanism does provide high
clamping security, but on the other hand edge or
insert indexing is inconvenient and time consuming
and the top clamp obstructs the chip flow – especially
during internal turning applications.
ISCAR’s new LR 4TL TOP LEVER combines the
advantages of both systems. It firmly holds the insert
in the pocket and also exerts an upper force on the
rear side of the insert. It leaves the insert rake face
unobstructed for free chip flow, while maintaining
convenient insert handling and extremely high
clamping security.
The new LR 4TL TOP LEVER can replace the
standard LR 4 lever in any tool.
