Overview

The TestingGmbH LFM Electromechanical Floor-Standing Testing Machine series (150 to 400 kN) is engineered for high-precision tensile, compression, bending, and shear testing of metals, alloys, fasteners, composites, and rebar. Driven by a brushless, high-response AC servomotor through dual precision ground ball screws and guided by dual steel auxiliary columns, the system guarantees superior axial and lateral stiffness. Complies with ISO 7500-1 Class 0.5, ISO 6892-1, ASTM E8, and ASTM A370.

Applications

Tensile testing of metals, alloys, and welded specimens
High-strength fastener and structural bolt testing
Composite and aerospace material characterization
