Mainframe: |
| |
The machine adopt double space door type structure. High accuracy, wide range and stable AC servo motor drive the ball screw pair rotating through syn-deceleration system. The ball screw pair drives the middle crosshead and makes the tension/compression/ bending attachment moves up and down to realize the load and offload to the specimen. This structure has enough stiffness to apply high efficiency and stable moving. Key parts are processed on our own processing center to ensure the accuracy of the load frame. Ball screw is E5 class |

Features: |
|
Complete computer controlled: The whole measuring and controlling system adopts specific PC control card used for testing machines, realizing the data zero and plus adjustment, which has very high reliability.
Supporting multi-transducers
Realizing the database management of the test data which are stored according to the standard format; facilitating other software to analyze and transfer.
Perfect programming by auto program control, every control mode can smoothly shift to another one. Fulfilling the test requirement of all kinds of materials with every test standard home and abroad.
Control software has the auto-adjusting function of test hardness, which assures that the system works with every kind of specimen hardness.
Perfect graphic function realizing the arbitrarily magnifying, decreasing, equaling, adding, indicative display and print of all kinds of test curves, the test point searching as well as the simultaneous display and print of several kinds of test curves. Data processing supposes self-disposing and input disposing of graphic human computer interaction, which facilitates the check and contrast of the test result.
The user can self -define the output of the test report, which makes the report format have very high flexibility.
Modularization design facilitates the software upgrading, function spreading as well as the second development.
All the crucial parts were processed by our own processing center to guarantee the high accuracy of machine. |
