Hardness Testing Machines

For Rockwell, Rockwell Superficial & Brinell Testing)

Principal :

Rockwell & Rockwell Superficial 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.Brinell test consists of forcing a hardened ball into surface of a test piece with a specified test-force and measuring the diameter of indentation for evaluation of Brinell hardness number.

Operation :

For Rockwell & Rockwell Superficial Test :In case of 'RASN' series machines for Rockwell & Rockwell superficial tests a preliminary test force in first applied and then indicator is automatically set for zero. Quickly thereafter an additional test force is applied without removing the preliminary test force. When the penetration is stabilised, the additional test force is removed and the hardness number is shown directly on the indicator.

For Brinell Test :

The operation is exactly same as above. However, the diameter of impression is measured outside of machine by Brinell microscope. Brinell hardness number is found out by referring corresponding hardness tables showing hardness number against dia. of indentation for specified ball diameter and test force.

Universal Testing Machines

Loading accuracy as high as + 1%.Suitable at variable speeds to suit a wide range of materialsContinuous roll autographic recorder supplied as standard to enable study of the behaviorof materialsMotor driven threaded columns for quick effortless adjustment of middle crosshead to facilitate rapid fixing of test specimen.High reading accuracy due to large size and design of dialWide range of standard and special accessories, including load stabilizer.Easy change from plain to threaded and screwed specimens.Large effective clearance between columns enables testing of standard specimens as well as structures.Simple controls for easy of operation.Robust straining frame of an extremely rigid construction.Safe operation ensured be means of safety devices.

Application :

Universal Testing Machine is designed for testing metals and other materials under tension, compression bending, transverse and shear loads. Hardness test on metals can also conducted.

Principal of Operation :

Operation of the machine is by hydraulic transmission of load from the test specimen through pressure transducer to a separately house load indicator. The 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 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 autograpic recorder. the deflection of the pendulum represents the absolute load applied on the test specimen

Return movement of the penulum is effectively damped to absorb energy in the event of sudden breakage of a specimen

Machine consists ofStraining 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 crosshead 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 by relieving the cylinder and ram of any possible side loading by the provision of ball seating.
An enlogation scale with a minimum graduation of 1mm, 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 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 operated 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 rangee 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 favourable hydraulic ratios producing relatively small frictional forces. Pressurised 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 reliabilty of operation. The load transmitted to the dynamometer is transferred through a pendulum to the load indicator

Accuracy and Calibration :

All Electronic Universal Testing Machines are closely controlled for sensitivity, accuracy and calibartion during every stage of manufacture. Every machine is then calibrated over each of its measuring ranges in accordance with the procedure laid down in British standards. 1610 : Part1 : 1992 and IS : 1828 : Part1 : 1991.
Electronic Universal Testing Machine comply with Grade "A" of BS : 1610 : Part1 : 1992 and class 1 of IS-1828-Part-1:1991. An accuracy of+1% is guaranted from 2% to 100% of the capacity of the machine. Below 20% of the selected range, the maximum permissible error is 0.2% of the full load reading.

Autographic Continuous Roll Load-Elongation Recorder:

This unit is of the pen and drum type and is supplied as standard. The horizontal motion of the pen products the ordinate of the diagram and the drum rotation products the extension ordinates, in the ratio of either 1:5 or 1:10

A continuous roll of graph paper is stored inside the drum and is easily replaced

Impact Testing Machines

The pendulum Impact Tester, Model IT-30 is designed for conducting Izod, Charpy test. The test methods confirm toBS : 131 : Part 4-1972 (Amended 15 Aug. 1993) BSEN : 10045-2 : 1993 & ASTM : E-23-94a.

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 it's position.

Charpy Test :

The charpy test piece rests on alloy steel support anvils, fitted on the base of the machine rigidly held in position by Allen screws. End stopper is provided for quickly and accurately locating the test piece centrally between the supports.

Izod Test :

The Izod test is clamped vertically in Izod support fitted on the base of the machine. The support is provided with a machined vertical groove to suit the test piece size. The front clamp piece and the Allen screw enable clamping of the test piece in correct height with the help of Izod setting gauge supplied.

This impact tester offered with 300J energy exclusively for Charpy test confirming to ASTM E-23. This machine is geometrically checked in the works to the more stringent requirements of the American standard. The accuracy of the machine is then verified by PROOF TEST by testing standard test specimens supplied the NIST, USA.

Application :

Compression Testing Machine is designed to test materials and other materials under compression, bending, transverse and shear loads. Hardness test on metals can also be conducted.

Principal of Operation :

Operation of the machine is by hydraulic transmission of load from the test specimen to 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 piston of the dynamometer is constantly rotated to eliminate friction. 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 and a table coupled with the ram of hydraulic cylinder, mounted on robust base. The cylinder and the ram are individually lapped to eliminate friction. The cross-head is connected to two screwed columns and is driven by a motor, for rapid adjustment of test height.
An elongation scale with a minimum graduation of 1.0 mm, is provided to measure the deformation of the specimen.
Compression, transverse, bending, shear and hardness tests are conducted between the lower cross head and the table.

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 no pulsating oil flow. Hence the load application is very smooth.

Hydraulic Controls :

Hand operated wheels are used to control the flow to and from the hydraulic cylinder. The regulation of oil flow is infinitely variable. Incorporate in the hydraulic system is a regulation valve, which maintains a practically constant rate of table movement.

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 dynamometersystem. 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 drum 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 ratio of either 1:5 or 1:10.
A continuous roll of graph paper is stored inside the drum and is easily replaced.

Accuracy & Calibration :

AII Compression 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 and IS : 1828, FIE Compression Testing Machines comply with Grade "A" of BS : 1610 and class 1 of IS 1828.
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.

Special Accessories :

These include load stabilizer, Brinell test attachment, Bend Test attachment, Shear Test attachment and a wide range of accessories offered on request at additional cost.

Installation :

It is recommended that machines be erected on a foundation. Details on foundation can be given on request.FIE reserves the rights of change in the above specifications due constant improvement in design. The dimensions given above are all approximate.
