Correct Clamping Force Every Time

Knowing that the tool clamping force meets machine builder specifications is of vital importance. The correct clamping force on machining centers provides a sound connection between spindle and tool. A drop in clamping force can indicate worn or broken springs and other problems with the drawbar. Insufficient clamping force may result in accidents should the tool unclamp during machining. ForceCheck is an innovative dynamometer that accurately measures tool clamping force on machining centers.

  • Benefits of Proper Clamping Force:
  • Reduces Wear on the Machine Taper
  • Improves Product Finish
  • Eliminates Fretting
  • Increases Tool Holder & Spindle Life
  • Improves Machine Accuracy
  • Helps Prevent "Stuck" Tapers
  • Reduces Tool Breakage, Vibration & Wear
  • Saves Money on Maintenance Costs

Avoid Unexpected Downtime

Tool clamping force is essential for good performance, but it is often never measured after a machine is put into service. Regular verification allows problems to be detected early so that maintenance and repairs can be scheduled. As a result, emergencies and unexpected downtime can be avoided. When troubleshooting, ForceCheck allows quick diagnostic verification of drawbar performance. Additionally, ISO 9000 requires periodic verification of a machine's important accuracy parameters.

ForceCheck In Use

Instructions:

  • Application — The ForceCheck pull-force gauge measures the clamping force of power drawbars on machining centers.
  • Retention Knobs — For proper measurement of pull-force on standard taper machines, the correct retention knob for the machine must be used with the force-sensing bar. We recommend always using the same retention knob for measuring clamping force.
