These machines are electro mechanical screw driven machines with precision screw and column construction and variable speed drive. Tow option are available mainly Acme threaded screw with DC Motor drive & ball lead screw with servo drive. The machines are suitable for studying mechanical behavior of various materials like metals, polymers, elastomers etc. These machines are easy to operate and they offer excellent performance and flexibility to meet the needs of modern testing requirements. The machines confirm to IS, BS & ASTM standards. These machines are available with following options depending upon test requirements and budget, best combination can be selected. DRIVE - SD: Drive dd is with DC motor with thyrister drive to give speed ratio As per sample std. Requirement. DRIVE - SD: Drive SD is with servo motor & PWM transister drive to give speed ratio As per sample std. Requirement.
