Proper clamping force:
Knowing that the tool clamping force meets machine builder specifications is of vital importance. 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.
This critical performance – the tool clamping force – is often never measured after a machine is put into service. Regular verification allows problems to be detected early so 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.

The ForceCheck pull-force gage measures the clamping force of power drawbars on machining centers.
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.
Basic Operating Instructions
The ForceCheck readout has several options that can be selected using the Function and Mode buttons
Force: displays only the force on the top line of the display.
F/PkHold: displays the force on the top display line, and the highest force read on the bottom line. This peak value can be reset with the zero button when the force sensing bar is unclamped.
Pound: display clamping force in pounds.
AutoOff On/Off: With AutoOff on, the readout will automatically turn itself off after approximately 1 minute of inactivity.
Note: the On/Off and Zero buttons do not function when in a menu.
The readout unit has a removable rechargeable Nickel Metal Hydride (NiMH) battery. Because NiMH batteries have no "memory effect", the battery can be charged even when it is not empty. A charger is included with the ForceCheck gage. Charging time for a completely empty battery is approximately 12 hours
To ensure accuracy within design specifications, as is with any other measuring instrument, periodic calibration by the manufacturer is strongly recommended. Additionally, the software in the readout should be updated to the latest revision. Please send back the included product registration card. Sending back the card will allow us to contact you when the gage is due for calibration.
