Bespoke Chuck for Runout Checking
Home > Projects
Project overview
A customer manufacturing large flywheels for diesel generator sets required a reliable method to check runout. Since flywheels must run concentric and true to avoid vibration, the checking process had to deliver high accuracy and repeatability.
The challenge was to design a bespoke chuck capable of securely holding these large, heavy components while ensuring precise concentricity during testing.
the solution
We delivered a robust and accurate chuck system tailored to the customer’s needs:
-
Heavy-Duty Structure – Steel framework with high mass provided the necessary stability.
-
Precision Chuck – A custom-designed, ground, and wire-eroded chuck ensured concentricity and repeatability.
-
Durability – The chuck was hardened throughout for long-term performance.
-
Simple Operation – Powered by a pneumatic cylinder for reliable and efficient actuation.
-
Bespoke Design – Specifically engineered for the customer’s flywheel components.
