Tensile Testing Machine

 

Tensile Testing Machine - Computerised - Mech.CS.TNE

Mech.CS.TNE series machines are electronic screw driven machines with precision screw and column construction and variable speed drive. These are high precision, high performance universal testing machines, maximum capacity up to 100 kN. With the help to computer and micro-computer, all the operations from control of load to processing of data are carried out with excellent performance, reliability, flexibility and easy operation.
The machines are suitable for studying mechanical behavior of various materials like iron and metals, rubbers, 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 with DC motor drive and ball lead screw with servo drive. The machines confirm to IS, BS & ASTM standards.
