These electro-mechanical materials testing machines are fitted with a ball lead screw drive.

• Available in 300, 400, 600, 1200 and 2000 kN (30 - 200 tonnes) versions.
• Wide measuring range allows precise determination of even small test loads without re-tooling.
• Long travel combined with comparatively low build-height provides trouble-free specimen clamping and user-friendly testing over a wide range of specimen lengths.
• Low-maintenance, pre-stressed ball lead screws ensure accurate, long-term tensile and compression testing, backed by a robust, extremely stiff load frame.
• Standard tests using Zwick testXpert^® software require only single-button operation.
• 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 tools.
• Should new test requirements arise, additional test tools (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).
