Technical Resources On Force Checking
Find out more details on why force checking is important. Improve tool life and part finish, protect your spindle and ensure machining accuracy, predict problems with the spindle's Belleville / disk spring stack, check for the role that friction plays in the clamping system and for proper lubrication, operator safety, and compliance to standards.
Drawbar forces in this document are sourced from international standards and gripper manufacturers. This information is for reference only: For specifications applicable to a specific machine, the machine builder should be contacted. Depending on the application, it is typical for a machine builder to design a machine for higher or lower forces.
Our testing is performed under traceable certified laboratory conditions. Many variables (friction, retention knob tolerances, spring pack settling, etc.) will influence the repeatability of measurements under normal operation in a factory environment. The measurement standards and instruments used during calibration are in accordance and traceable to the United States Institute of Standards and Technology (NIST). As with any sensitive measuring instrument, periodic re-calibration is strongly encouraged. Annual re-calibration is recommended. Contact us for more information.
