E series with ball-screw drive

E-series electro-mechanical materials testing machines are equipped with ball-screw drive and are available in 330, 400, 600, 1200, 1600, 2000 and 2500 kN versions (33 - 250 tonnes).

Key advantages and features

Description

  • These materials testing machines feature a large measurement range, allowing precise determination of low test forces with no need to re-equip the testing machine.
  • Low-maintenance, pre-stressed ball-screws backed by a robust, extremely stiff load frame ensure accurate long-term tensile and compression testing.
  • Extremely stiff, robust load frame
  • Operator involvement in standard tests using testXpert II testing software is reduced to pushing a single button.
  • Modular design throughout the system allows the entire Zwick accessory range to be used, including a wide variety of extensometers, specimen grips and other test fixtures.
  • Should new testing requirements arise, additional test fixtures (e.g. calibration blocks) are easily installed via a T-slot or screw system.
  • Can be tailored to customers’ specific requirements (e.g. test area dimensions, test devices, specimen grips, test speed ranges, testing software).

Advantages and features

  • Convenient operating height for specimen insertion with grips installed.
  • testXpert II's intelligent test environment concept reduces set-up times and increases productivity.
  • The robust load-frame features four hard-chromed guide-columns and massive base and moving crossheads, ensuring excellent guidance properties and a high level of machine stiffness.
  • Maintenance-free digitally controlled AC drive technology combined with an innovative motor feedback system allows excellent constant speed characteristics to be achieved even at extremely low speeds.
  • The backlash-free pre-stressed precision ball-screws with digitally controlled AC servo drive allow virtually maintenance-free operation.
  • The large test area combined with low overall height enables specimens and components with a wide range of lengths to be tested.
  • The testing machine is positioned directly on the ground with no foundation.
  • Compliance with the statutory safety requirements of the EC Machinery Directive is ensured in all materials testing machines, while an EC Declaration of Conformity accompanies every machine supplied.
  • Only the latest safety technology and proven industrial components are used.
  • The highest degree of safety for the operator, test results, specimen material, and testing system are guaranteed.
