Features

Universal Testing Machine have a wide range of applications. Anumber of materials, metals in different form and shapes can be tested for variety of tests like Tension, Compression, Transverse, Bend, Shear, Brine Hardness etc. Special attachments are also available for testing of Flat Belts, Chain Links, Wire Ropes etc.

Loading Frame
The base has a hydraulic cylinder at its center and two main screws at both ends. The middle cross head is mounted on screws through main nuts. the middle cross head can be moved up or down through chain transmission and geared motor to adjust the initial tensilel compression clearance. On the piston, rests an assembly of upper, lower cross head and two columns. The individually lapped cylinder piston assembly ensures smooth axial force with minimum friction.

Control panel
Hydraulic circuit - it consists of hydraulic power pack which has a directly driven radial plunger pump which gives a continuous non pulsating flow of oil pressure up to 250 bar. a pressure compensated needle type flow control valve is provided to control the oil flow to cylinder there by achieving a desired piston speed. Infinitely variable speeds an be obtained with help of valves. Optionally this can be controlled from electronic control system.

Loading Rate / Straining Rate Control
This is superfine controlling system which controls loading rate I straining rate as per commands from electronic machine control system. With UP / DOWN Keys on electronic control system loading ratel straining rate is adjusted. Fine UTM Software can send loading rate / straining rate to electronic control system.

Load Measurement System
The oil pressure in the main cylinder is also transferred to an electronic pressure transducer which goes proportionate signal to computer electronic unit. both the motors for hydraulic operation and cross head motion are controlled by buttons on electronic control system and they have interlocks to prevent simultaneous working of motors. The electrical panel is housed in control panel.

Displacement measurement is carried out by means of a rack and pinion on rotary encoder. Encoder signal is fed to electronic control system to get displacement.

Operation
Tension test is conducted by gripping the test specimen in the upper and middle cross head. Compression, Bending, Transverse, Shear and Hardness tests are conducted between the middle and lower cross head by using appropriate fixtures. The rapid adjustment of middle cross head facilities easy fixing of tensile I Compression specimens of different lengths.

Hydraulic controls are through hand operated valves, ergonomically placed for ease of control. Optionally valves can be controlled from electronic control system. Adequate safeties for over load and over travel are incorporated and emergency switch is provided.

Accuracy & Calibration
Every machine is calibrated in accordance with procedure laid down in BS - 1610 - 1964 IS 1828 - 1991. 'FMI' Computerised Universal Testing Machines comply with grade A of BS 161()"1964 and Grade 1.0 of IS 1828 - 1991. An accuracy of + -1% guaranteed from 2% to 100% of capacity of the machine. in the computerised UTM, the computer is an integral part of the entire system and not just on ADD - ON feature. This puts a lot of power and versatility into the hands of the operator and makes the system much more self contained then usual, as it includes many functions usually only available as additional ( often expensive) optional features.

Features of -Fine UTM software
