Digital Hydraulic Universal Testing Machine
Brand | VMW |
Model No. | VMW-HUTM |
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 seatings.
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.
