Application

ARUN Universal Testing Machine is designed for testing materials and other materials under tension, compression bending, transverse and shear loads.

Principal of Operation
Operation of the machines is by hydraulic transmission of load from the test specimen to a separately housed load indicator. The hydraulic system is ideal since it replaces transmission of load through levers and knife edges, which are prone to wear and damage due to shock on rupture of test pieces.
Load is applied by a hydrostatically lubricated ram. Main cylinder pressure is transmitted to the cylinder of the pendulum dynamometer system housed in the control panel. The cylinder of the dynamometer is also of self-lubricating design. The load transmitted to the cylinder of the dynamometer is transferred through a lever system to a pendulum. Displacement of the pendulum actuates the rack and pinion mechanism which operates the load indicator pointer and the autographic recorder. The deflection of the pendulum represents the absolute load applied on the test specimen. Return movement of the pendulum is effectively damped to absorb energy in the event of sudden breakage of a specimen.



Machine consists of Straining Unit
This consists of a hydraulic cylinder motor with chain and sprocket drive and a table coupled with the ram of the hydraulic cylinder, mounted on to a robust base. The cylinder and the ram are individually lapped to eliminate friction. The upper cross-head is rigidly fixed to the table by two straight columns. The lower cross-head is connected to two screwed columns which are driven by a motor. Axial loading of the ram is ensured be reveling the cylinder and ram of of any possible side loading by the provision of ball seating's.
An elongation scale with a minimum graduation of 1 mm is provided to measure the deformation of the specimen. Tension test is conducted by gripping the test specimen between the upper and lower cross-heads
Compression, transverse, bending, shear and hardness tests are conducted between the lower cross head and the table. The lower cross-head can be raised or lowered rapidly by operating the screwed columns thus facilitating ease of fixing of the test specimen.



Control Panel
The control Panel consists of a power pack complete with drive motor and an oil tank, control valves a pendulum dynamometer a load indicator system and an autographic recorder.



Power Pack
The power pack generates the maximum pressure of 200 kgf/cm2 the hydraulic pump provides continuously non-pulsating oil flow. Hence the load application is very smooth.



Hydraulic Controls
Hand operates wheels are used to control the flow to and from the hydraulic cylinder. The regulation of oil flow is infinitely variable incorporated in the hydraulic system is a regulating valve which maintains a practically constant rate of piston movement. Control by this valve allows extensometer readings to be taken.



Load Indicator System
This system consists of a large dial and a pointer. A dummy pointer is provided to register the maximum load reached during the test. Different measuring ranges can be selected by operating the range selection knob. An overload trip switch is incorporated which automatically cuts out the pump motor when the load range in use is exceeded.



Pendulum Dynamometer
This unit permits selection of favorable hydraulic ratios producing relatively small frictional forces. Pressurized oil in the loading cylinder pushes up the measuring piston proportionately and actuates the special dynamometer system. The piston is constantly rotated to eliminate friction. The dynamometer system is also provided with an integral damper and ensures high reliability of operation. The load transmitted to the dynamometer is transferred through a pendulum to the load indicator.



Autographic Continuous Roll Load-Elongation Recorder
This unit is of the pen and drums type and is supplied as standard. The horizontal motion of the pen produces the load ordinate of the diagram and the drum rotation produces the extension ordinates in the ration of either 1:5 or 1:10.



Accuracy & Calibration
II ARUN Universal Testing Machines are closely controlled for sensitivity, accuracy and calibration during every stage of manufacture. Every machine is then calibrated over each of its measuring ranges in accordance with the procedure laid down in BS : 1610 : Part 1 : 1992 and IS 1828 : (Part 1) : 1991. ARUN Universal Testing Machines comply with Grade "A" of BS: 1610: Part 1:1992 and class 1 of IS 1828: (Part1): 1991
An accuracy of + 1.0% is guaranteed from 20% from 20% of the load range selected to full load. Below 20% of the selected range, the maximum permissible error is 0.2% of the full load reading.

Digital Rockwell Hardness Testing Machines

Digital Rockwell Hardness Testing Machines
Principal
Rockwell, Rockwell superficial & Rockwell cum Brinell tests consists of forcing 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.
Various parameters of test can be set on front panel by operation of key board and observing LCD display Viz high / low limits, dwell time, auto / manual start, printer selection, scale selection etc. All set data can be very ARUN edited by pressing SCL key one after another.
Machine operation is very simple. The normal mode is a bar followed by "SET" indication. Raise elevating screw slowly through bar indication till "SET" position which will show "PRESS START" indication. Now press "START" button. Loading / unloading cycle will be completed and hardness is shown on LCD display with High / Good / Low indication. Lower down elevating screw. Panel will show normal mode for next test. Also when required 'AUTO START' on front panel by operation of key board & observing LCD Display then raise elevating screw slowly through bar indication till "SET" position then it will starts loading / unloading cycle automatically & hardness is shown on LCD Display with High / Good / Low indication.

ARUN's new 'RASNE' series of Hardness Testing Machines come with much improved design & look with following major design changes
  • This is motorized machine having automatic loading/unloading cycle suitable for production testing.
  • The machine body is having a taper front look and a large size read-out in the front. The machine is powder coated for better look. The paint shade do not fade and machine looks like new over year.
  • The elevating screw of machine is guided in a hardened and ground bush, not allowing movement of elevating screw more than 0.05 mm when raised to full height. The accessory is retained for years together due to hardened bush.
  • A hardened and ground stepped bush is fixed on top of main screw for location and rest surface. This guarantees no change in results due to rough handling of test table or test piece. It means a trouble free long life machine accuracy.
  • An antifriction linear bearing with almost no clearance is provided for a perfect vertical movement of loading plunger with minimum friction. This enables testing of small dia. Pin or ball upto 3 mm dia
  • These models are provided with automatic working cycle and digital LCD display with 0.1 Rockwell resolution. This insures productivity with better accuracy.
  • IS:1586:2000 for Rockwell and superficial test. IS:2281:2005 for Brinell hardness test.

General Description
The pendulum Impact Tester, Model IT-30 is designed for conducting Izod, Charpy test. The test methods confirm to BS : 131 : Part 4-1972 (Amended 15 Aug. 1993) BSEN : 10045-2 : 1993
The Pendulum is mounted on antifriction bearings. It has two starting positions, the upper one for Charpy & the lower one for Izod testing. On release, the pendulum swings down to brake the specimen and the energy absorbed in doing so is measured as the difference between the height of drop before rupture of the test specimen and is read from the maximum pointer position on the dial scale.

(It is read on digital readout in case of electronic machines.)
There are two strikers and one combined support available for fitting in to the pendulum and on to the base of the machine for the Izod, Charpy test respectively, Changing from one striker to another is achieved simply by fixing the new striker into its position.
