A new version of the F-senso spindle pull-in force measuring device from Röhm Products of America is engineered for use with clamping systems for smaller tool shanks including HSK A 25, A 32 and A 40 and steep taper SK [CAT/BT] 30. Initially introduced for shank sizes from HSK 50, HSK 125 or SK 40, SK 60, the F-senso device measures the pull-in force of machine tool clamping systems, making it possible to detect changes in force before they affect machining quality.
Fitted with adapters for HSK or steep taper shanks, the F-senso device is pulled into the spindle taper of the machine tool and provides an exact measure of pull-in force. Force readings cover a range of 0 to 15 kN (3,370 lbs.)
The adapters are contoured to permit use with a machine's automatic toolchanger, and a revolving ring with a scale makes it possible to simulate the tolerances of the tool and the machine spindle over a wide range.
User-friendly features of the F-senso device include the ability to automatically save the last displayed reading for reference, and extended operating times provided by a 9V battery.
The pull-in force of a spindle's tool clamping system has a crucial role in processing quality and safety. The new compact F-senso design makes it easy to monitor and detect changes at an early stage and take any countermeasures necessary.

automatic toolchanger
Mechanism typically included in a machining center that, on the appropriate command, removes one cutting tool from the spindle nose and replaces it with another. The changer restores the used tool to the magazine and selects and withdraws the next desired tool from the storage magazine. The changer is controlled by a set of prerecorded/predetermined instructions associated with the part(s) to be produced.

shank
Main body of a tool; the portion of a drill or similar end-held tool that fits into a collet, chuck or similar mounting device.

toolchanger
Carriage or drum attached to a machining center that holds tools until needed; when a tool is needed, the toolchanger inserts the tool into the machine spindle. See automatic toolchanger.
