Linear units apply the test force in tensile or compression testing to a defined point at a speed of up to 30,000mm/min, for a load range between 1kN and 5kN
Exact loads, defined ways, high speeds: that's how part and component testing should run, says Zwick.
No matter whether testing mattresses, headrests, gear shifts or brake pedals, the requirements are invariably the same.
And this applies not only for testing in the production line but also for fatigue testing of parts, where the material properties are stressed to the limit.
With this in mind, Zwick has rounded off its product offering and developed a new line of electric actuators.
For the load range between 1kN, 2kN, and 5kN, Zwick offers linear units which apply the test force in tensile or compression testing, to a defined point at a speed of up to 30,000mm/min.
In fact, these performance data cover nearly the full range of components testing.
The decisive advantage of this modular system is the control of the actuator, which is done via the Zwick testControl control electronics, and the parameter input effected via the proprietary Zwick testing software testXpert.
With this package, all the functions of a standard testing machine are made available, e.g defined ways to specific positions with highest precision, variable force regulation or bump-less transfer between modes during testing.
Additionally, this product fits smoothly into the mechanical concept followed by all Zwick testing machines, guaranteeing that all tools and accessories making up the Zwick product portfolio can be deployed.
Zwick says it is able to supply custom tools should the actuator be needed for special test jobs, eg joining, pressing-in or assembly process steps.
A further plus of the electric actuator is its flexibility when incorporating it into the testing device.
The actuator can be installed in a legacy load frame or in any location desired in the line.
Or it may even be used as a supplementary second test axis in a materials testing machine.
The electronics are compact, requiring only a very small space in a separate switch cabinet meeting IP54 requirements.
