Computer Control Universal Testing Machine

Applications :

• A wide variety of tests can be conducted on this machine viz. Tensile, compressive, transverse, Peel test for adhesive tapes
• The material, like rubber, plastics, ferrous metals, non ferrous metals, etc. can be tested as per different standards
• The test specimens can have a number of forms like round, flat, threads, wires, dumbells, fabric, belts, straps, ropes, etc. or sometimes components directly also can be tested
• In order to cater to this variety of forms, shapes and materials, a range of grips can be offered

Description :

• The computer controlled universal testing machines are rugged, versatile, user friendly, accurate and can test a variety of material
• A wide choice of grips are available to suit the application
• The windows based software is comprehensive and covers most of the applications
• The automatic calculation of parameters from the observed test values, real time graphs, storage and retrieval of data are immensely useful
• The state of art electronics, high quality material used, and the user friendly software makes the machine reliable and user friendly
• The machine comprises of a rigid assembly of lower table and top plate connected by guide rods
• The two ball screws (One on left and the other on right) also are mixed in this assembly
• The crosshead, in the center, houses the nuts of the ball screws
• The entire assembly is fixed on the base, which accommodates driving arrangement base
• A set of bellows protects the ball screws from ingress of dust

The interface and computer are placed on a computer table by the side of the machine :

• Standard Accessories
• Basic machine along with one load cell and a pair of compression plates.
• Windows based on users friendly software.
• Salient Features
• Method of loading by re-circulating ball screws.
• AC servo motor for precise crosshead control with infinitely variable drive.
• Load measurement by load cell
• Over travel safety by fixed and settable limit switches at both ends.
• Overload protection for load cell by electronic control
• Single from windows based user friendly software
• Test data and reports are stored in access database
• User programmable strain rates in many steps
• User can select results from available result list for report
• User defined reports
• User can select test from templates and can start similar test
• Variable sample break detection.
• Tare load and reset elongation facilities available
• Load and Elongation is continuously displayed on screen
• Statistical output for a batch in report
• Simultaneous display of two graphs is possible in real time testing
• On line display of load and displacement (Stress, Extension, strain) etc. while test is conducted.
• Real time graph of load and Elongation, load and time, stress and strain is displayed and is auto scaled
• User selectable units for load and displacement (N, kg, kN, lbf, mm, inch, etc)
• Report can be printed on any printer with two graphs
• Large storage space for storing test data and results
• Provision of calculation of Load and Elongation at yield, peak load and load at break, Yield stress, Ultimate stress, etc.
• Specific software for tensile, compression, shear test and other tests.
• If Electronic Extensometer is used then proof stress values from 0.1% to 1% can be determined.
• Software will give alert to user to remove extensometer when load crosses the proof load value
• In order to cover wide load range, more load cells can be supplied (optional), In that case has to select the load cell for test
• Standard load resolution is with 10,000 counts. Finer resolution with 20,000 or 50,000 counts can be offered (optional)
• Other slower cross head speed on specific request (optional).
