Thermal Shrink Chucking System
Thermal Shrink ER Collet Chucking System is
an enhancement to the existing popular ER system.
The SHRINK collets utilize the thermal shrink phenomenon for
rigid clamping of solid carbide cutters. This new system provides
higher torque, precision runout and better repeatability. The
SHRINK collets with their slim design and various projection
lengths allow the user to reach into deeper shaped cavities and
perform narrow milling applications.
Tungaloy offers a complete system for SHRINK ER collets,
including a uniquely designed heating unit with a portable
heating handle. The system is equipped with
a high-tech temperature control for easy
and practical use at the machining center
or in the tool room.
