AC Servo Controlled Ball Screw Type Universal Testing Machine

Electro-Mechanical Servo Controlled Universal Testing Machine



AC Servo Controlled Ball Screw Type Universal Testing Machine :

FMI make the 'F' series machines are electronic screw driven machine with precision screw and column construction and variable speed drive. These are high precision high performance universal testing machines, maximum capacity up to 200 kN. With the help of computer and micro-computer from control of load to processing of data are carried out with excellent performance, reliability, flexibility and easy operation.The machines are suitable for studding mechanical behavior of various materials like iron & metals, rubber, plastics, ceramics, fabrics, composites, cables and wires. As a matter of fact, it is an indispensable instrument for the modern industries. Two options are available mainly acme threaded screw AC motor drive and ball screw with servo drive. The machines confirms to IS, BS & ASTM standards.
