Testing new parts and concepts

Hilchenbach/Germayn (EWMenn) – EWMenn GmbH & Co. KG has its own testing facility to aid in the development needs of customers and die manufacturers alike. Optimum conditions are provided for thorough testing of new parts and concepts. This includes ability to confirm suitability and performance of new die geometries through documented test series. Testing is available against a fee depending on requirements. EWMenn is a manufacturer with renowned reputation worldwide for constantly working to meet users` highest expectations, especially when it comes to performance, precision, efficiency, flexibility and the safety of thread rolling machines. Close cooperation with customers is a major objective. Offering use of the testing center aids this objective via the wide variety of testing modes and techniques that can be provided. The test center features advanced technology and includes a specially prepared EWMenn Model AF-14 High-Speed, Flat-Die Thread Roller. This machine is equipped with hydraulic die carrier clamping, push button die match, push button height adjustment for feeder and feedrails and many other features that allow reliable and repeatable testing. Maximum available die length for the AF-14 is 230/255mm or Waterbury #40. Shorter dies may also be used, of course. A Brankamp PK 4U Process Control System has been integrated to the EW Menn Model AF-14 now installed at the test center. This system includes calibrated sensors for measuring actual pressure load at each of the machine’s four pressure screws as well as total combined rolling load. Electronic Die Match Control is an additional system feature that enables not only process control and documentation but also exact electronic measurement and monitoring of die match. Adaptive Die Match (ADM) is yet another system feature that continuously monitors and automatically corrects for imperfect die match in real time! Taken together all of the above-described items provide the optimum condition for research and development projects. This truly is as good as it gets! A further advantage: R&D work and test series can be undertaken away from the daily (and often distracting) production environment.
