Main functions of glass three-point/four point bending tester: this machine is suitable for compression and bending tests of tablet computers, mobile phone lenses, glass and other products, using servo motors, ball screws and original American force value sensors; It is an ideal testing equipment for relevant manufacturing enterprises, colleges and universities, scientific research institutions and technical supervision departments< br />
It is equipped with special test control software and clamping device, which can test the use performance of the lens. According to GB, JIS, ASTM, DM, ISO and other standards, the maximum test force value (minimum force value/average value), breaking force value, tensile and compressive strength, elongation, peeling strength, peeling force and other parameters are automatically calculated. The results are accurate, reliable and reproducible. It can also perform data rounding (GB8170) and print mechanical property indexes such as Fm, Rm, Rp, ReH, ReL, Re, A, Z, E, and load deformation, stress strain curves. Equipped with special three-point compression resistance, four point compression resistance and bending resistance tools; It is an ideal equipment for enterprises and supervision organizations to detect phase difference products and for teaching and research in scientific research institutions< br />
Introduction to the control software of glass three-point/four point bending tester; l

Software operating system language: Simplified Chinese/English. ll

Force value unit: N, KN, Kgf, Lbf, length unit: mm, cm, in, freely convertible

Automatic zeroing: when the computer receives the command to start the test, the measurement system will automatically reset to zero< br />
Display mode: data and curve are displayed dynamically with the test process< br />
Result reproduction: the test results can be accessed at will and the data curve can be re analyzed< br />
Results comparison: multiple test characteristic curves can be superposed, reproduced, magnified and analyzed by presenting a group of samples with different colors< br />
Emergency stop: emergency stop switch is set to cut off the power supply of the whole machine in emergency state< br />
Control mode of glass three-point/four point bending tester:

  Computer software sets speed, load break (break), running time and other control modes l

  Automatically judge material fracture, crushing, etc. and automatically stop the machine. Automatic return can be set to l

Curve type:

  Load displacement, load time, displacement time. l

  Stress strain, strain time, stress time< br />
 & nbsp; The vertical and horizontal coordinates of the curve can be set arbitrarily. l

Available test data:

  Maximum strength, minimum strength, breaking value, upper and lower yield strength, tensile strength, compressive strength, elastic modulus, elongation, maximum, minimum and average values of stripping interval, etc. With overload, overcurrent, overvoltage, undervoltage, overspeed, stroke and other multiple protection. l

  The data results are exported from the crystal report format currently adopted by the national standard< br />
