COMPANY PROFILE - BY PETER BRETT


job well, and then to electro-mechanical wrenches that took accuracy and accountability to an advanced level.


Open protocol wrenches not only did the job well, but recorded in detail and then sent the data on to a central system for ultimate accountability.


DAPTIQ


Alexander Grosser, Project Manager Industry 4.0, did a few demonstrations to show me just how advanced this system could become.


Using an augmented reality headset, a user in a production line for example could be guided towards bolts which need tightening in the correct order.


As this is done, a computer is recording the torques as they are applied and noting that they are correctly applied.


If for any reason the torque is not correct, the system notes and then stops the user so the situation can be rectified.


By basing the system on an open source platform, STAHLWILLE is hoping to encourage users to develop their own ways of managing and using the system to their own advantage.


Reading Station DAPTIQ is another system in development by STAHLWILLE that is constantly evolving, because users and R & D keep on finding out how much more potential there is in the idea.


It looks like a simple secure storage unit for tools. But the unit not only keeps the tools secure, it counts them to ensure that all the tools are present.


In modern manufacture and aerospace for example, it is too late to discover that a wrench has been left in an engine when you are about to take off. Once again, the software allows both STAHLWILLE and clients to customise the system to suit various needs.


More Expertise


It behoves a manufacturer of torque wrenches to have very accurate systems of recording exactly how well and accurately the wrenches are performing.


STAHLWILLE has developed a range of motorised calibration systems. The motorised bench automates the loading process, and the transducers use strain gauges to take the dozens of measurements which need to be taken into account when calibrating a torque wrench to the new ISO 6789-2:2017 standard.


TORKMASTER software records the measurements, and calculates the deviations and measurement uncertainty.


I did not realise quite how many variations there are when measuring performance.


Apparently, even the four sides of an adaptor can give diff erent readings on the same wrench set to the same torque.


This can be tricky when you consider there must be no more than a 1% deviation for the calibration of STAHLWILLE’s most accurate torque wrench, the SENSOTORK 713 to be passed.


And the Rough Stuff


Away from the refi ned electronic quiet of the demo centre, Chris showed me the actual manufacturing, assembly and fi nishing of the huge range of STAHLWILLE tools.


STAHLWILLE is not only torque wrenches; it is spanners, pliers, cutters, screwdrivers, sockets & ratchets, etc etc.


I enjoy watching ‘real’ manufacture, and STAHLWILLE has a range of heavy processes needed to make and fi nish a socket, as well as the capacity to assemble the delicate electronics in an electro-mechanical torque wrench and then test it.


Despite the noise of machines, the humans keep control of the factory fl oor, ensuring the continued production of thousands of items.


STAHLWILLE and the Future


It is clear that STAHLWILLE not only has a productive and innovative past, it is looking to the future too.


I have mentioned only a few key innovations, but the company is clear that precision manufacturing in the industrial sector will only become more important.


Key areas like aerospace, automotive and renewable energy already have niche demands for tools, but again, these needs will become even more complicated and demanding - a challenge STAHLWILLE is tackling head on.
