BILZ

“Clamping technology for precision tools”
BILZ, the market leader in inductive shrink-fit units, clamps tools with micron-level runout accuracy through its ThermoGrip shrink systems, tapping chucks and CNC tool holders.
The technology that clamps the tool to the machine
Why BILZ is this link of the chain
A cutting tool performs only as well as the chuck holding it. From its production in Ostfildern, BILZ supplies the world with solutions for precise clamping, defined movement and fast manual tool change.
ThermoGrip induction shrink technology heats the chuck in seconds and the tool slips into the expanded bore; as it cools, the chuck grips the tool with high runout accuracy and rigidity. Intelligent, fully automated and safe.
