Heat-Activated Toolholder

Constructed with an inside diameter slightly smaller than the shank diameter of standard cutting tools, the Shrinker heats up quickly by using a heat induction unit to expand the inside diameter. As the holder cools, the thermal contraction exerts a uniform pressure, allowing the toolholder to shrink down around the tool, keeping the shank securely in place with its concentric gripping strength.

The heat-activated toolholder has high concentric running accuracy, maximum guaranteed concentricity of 0.0002 in. or better, a safe frictional transfer of force, and it is suitable for high speed cutting applications. The Shrinker includes a transferable torque higher than that of standard milling chucks or collet chucks, a high radial stiffness, and simple tool clamping with no moving parts.

The induction heating unit is available in two vertical and two horizontal models. Several options are available including a sensor that detects the amount of heat introduced into the toolholder and shuts the machine off automatically to prevent overheating of the toolholder. Accessories include depth-setting units, locking rings, induction spacer rings, HSK coolant tubes, installation wrenches, and indirect coils for the heating unit.
