Updated clamping-force measuring deviceThe clamping-device manufacturer Hainbuch, which has a UK subsidiary in Cannock (www.hainbuch.com), has developed an updated version of its Testit clamping-force measuring device for external and internal clamping.

The new-generation device now comprises two parts: the Test Module (or measuring unit), which changes depending on the specific measurement application; and the IT Module (or ‘basic unit’).

The updated product can be used on multi-spindle machines, turning centres and machining centres.

Furthermore, it incorporates an additional module for measuring and recording the insertion force of hollow-shank taper tool-holders.

The Testit works as a modular system with “plug-and-play functions that can be viewed on a 10in tablet, via a USB stick or as a download”.

Previously, the Hainbuch Testit was only available as a complete unit, and users bought one Testit for external clamping, another for internal clamping and — depending on requirements — other Testit items for different sizes or specific applications.

Now, customers only need to purchase one basic unit, regardless of whether they need to measure the external or internal clamping forces or the pull-in forces.

The Test Modules are then added to the basic unit, significantly reducing costs when compared to alternative measuring devices; and with the plug-and-play function, each measuring unit can be detached from the base unit with just three screws, allowing customers to ‘swap out’ features quickly.

DIN EN: 1550 specifies that static clamping-force measurements are to be carried out at regular intervals. The new Testit device measures and records the clamping and draw forces, even in the case of special versions.

The program for visualising the measured values has three display variants that can be viewed via a tablet, while an integrated administration database allows users to select their current clamping device and their machine tool.

All data is maintained and clearly presented in the database (the measured values are archived as PDF and CSV files).

The languages available are English, French and German; others will follow.

Be seen in all the right places!
