Torsion Testing Machine is designed for conducting torsion and twist on various metal wires, tubes, sheet materials. Torque measurement is by pendulum dyanometer system. Torque ranges can be adjusted by auto torque selector. Torque can be applied to I specimen by geared motor through gear box. Autographic recorder gives the relation between torque and angle of twist. The accuracy of torque indication is ± of the true torque.

Rockwell, Rockwell superficial& Rockwell cum Brinell test consists offorcing an indentor (Diamond or Ball) into the surface of a test piece in two steps i.e. first with preliminary test force and thereafter with additional test force and then measuring depth of indentation after removal of additional test force (Remaining preliminary test force active) for measurement of hardness value. RASNE series machines are suitable for Rockwell, Rockwell superficial& Rockwell cum Brinell tests. These are motorized digital Hardness testers having LCD display for easy hardness measurement. The results are displayed in 0.1 Rockwell unit for more accurate measurement.

Principle of operation :The test specimen is subjected to load with hydraulic system and is measured precisely with pendulum dynamometer. Load is applied by a hydrostatically lubricated ram.The oil pressure in the main cylinder is transmitted to the cylinder of the pendulum dynamometer housed in the control panel, the dynamometer piston exerts a force proportionate to the hydraulic pessure.This force is transferred through a leverage system to a pendulum. Displacement of pendulum actuates the rack and pinion mechanism which operates the load indicating pointer. Return movement of pendulum is effec- tively damped to absorb energy in the event of sudden breakage of specimen.Machine comprises ofthe following: Strainung Unit : This consists of a hydraulic cylinder & piston mounted on a robust base. The loading frame consists of an upper crosshead, middle crosshead and lower table. The upper crosshead and lower table is connected by means of two plain hard chrome plated columns. The middle cross head is fitted on two hard chrome plated threaded columns. A reduction gear motor drives the chain and sprockets fixed at the bottom of the threaded columns for height adjust- men!. The cylinder and ram is individually lapped to eliminate friction.Axial loading of the system is ensured by provision of a ball seating under the lowertable. An elongation scale with least count of 1 mm is provided for measurement of deformation on various samples. Tensile test is conducted by gripping the test specimen between the upper and middle crosshead.Compression, Transverse, Bending and Shear tests are conducted between the Shear tests are conducted between the middle crosshead and the lower table.  Control Panel : The control panel consists of the hydraulic system .complete with drive motor, oil sump, pendulum dynamometer and the load indicating system. Hydraulic System : The power pack has a directly driven pump which generates a maximum pressure of 200 kgf/cm2. he hydraulic pump producs a continuous non- pulsating oil flow. Hence the load application is very smooth. Oil filter, oil stranier, air breather, oil level indicator and drain plug is provided in the power pack. A pressure compensated flow to the main cylinder. This maintains constant rate of piston movement andhence straining rate is kept constant. This valve is hand operated and gives infinitely variable oil flow to obtain different rates of straining. Pendulum Dynamometer : The oil pressure in the main cylinder actuates the special dynamometer system. Pressurised oil in the loading cylinder pushes up the measuring piston proportionately and deflects the pendulum. The piston is constantly rotated to eliminate friction. The system has effective damping arrangement to ensure smooth return of pendulum aftersudden breakage of test piece. This unit permits selection of favourable hydraulic ratios producing relatively small frictional forces. Load Indicating System : This system consists of a large dial and a pointer. Displacement of pendulum actuates the rack and pinion mechanism, which operates the load indicating .pointer. The pointer moves over a large dial indicating the load. A dummy pointer is provided toregister the maximum load reached during the test. Window type dial is provided for easy and clear changing of load range. Load / Elongation Recording System : A continuous roll ( A strip chart) type load-elongation recorder is provided for plotting load-elongation graph. Horizontal movement of the rack produces load ordinate of the diagram and drum rotation to elonga-tion ordinate, in the ratio of either 1:5 or 1:10.
