3-Jaw Power Chuck for the Digital Factory
September 1, 2025
The KNCS-matic is the latest clamping system in the KNCS power chuck family from SMW Autoblok. It allows automatic quick jaw change by a conventional industrial robot. This releases the base jaws with a release pin, replaces them and then fixes the next jaws with the pin.
"Interaction with industrial robots enables the KNCS-matic to achieve short set-up times, helping ensure reliable workpiece clamping with self-centering and repeat accuracy," said a company spokesperson. "Operators can work economically with the increasing variations within components without having to compromise on precision and production quality."
The KNCS-matic 3-jaw power chuck is available in six sizes, achieving a total clamping force of 100 to 250 kN depending on the size. The chuck can be used for a wide range of machining operations, since its jaws can be displaced or turned, and each jaw can be moved from 7 mm to 10 mm. In addition, KNCS-matic has a large passage of 52 mm to 165 mm, typical of the KNCS series. With speeds of 1,700 RPM to 6,000 RPM, the KNCS-matic helps ensure high machining speeds with consistently high precision. The Proofline seal from SMW Autoblok makes the chuck low-maintenance. It can be individually adapted to the relevant machining requirements with an extensive range of accessories, such as different jaws, an axial stop and a water flush.
SMW Autoblok supports workpiece processing on the way to the digital factory with automated clamping devices. Together with SMW-Electronics, the company can outfit the process for a fully automated quick jaw change. The jaws of the KNCS-matic can then be replaced with the MX-S mechatronic gripper from the MOTIACT product range. An inductive coupling system such as the F100 enables contactless transmission of energy and signals between the robot arm and gripper, realizing its rotation by 360° in both directions for easy jaw change.
