250MRS Automatic full Rockwell hardness tester

Automatic full Rockwell hardness tester, automatic measurement
model:250MRS
Brand:Affri 艾法利
Origin:意大利
Product Details >>

Italy AFFRI-250MRS automatic full Rockwell hardness tester, the original imported hardness tester is electronic closed-loop loading, automatic measurement, can measure Rockwell, surface Rockwell, if necessary, can be configured to measure Brinell and Vickers hardness. It has the characteristics of accurate, efficient, fully automatic, one-key completion of the entire test process, stable testing, high reliability, and no need to adjust the level...



Product parameter

Unique advancement

-High rigidity structure design makes the whole frame without any deformation during the test

-No need to perform two measurements, one measurement is extremely effective

-Loading load is controlled by a closed-loop system load sensor, no task load impact error, monitoring frequency is 1000HZ, the whole process accuracy is 0.1%, the industry's high monitoring frequency

-The indenter is directly connected to the load sensor without any intermediate structure. The load sensor directly measures and monitors the load on the indenter and adjusts it. With the addition of coaxial loading technology, there is no lever structure, and it is not affected by friction and other factors.

-The depth measuring device is directly connected to the indenter without any intermediate structure, and the main frame is a floating flexible connection (AFFRI*). The depth measuring device measures the maximum depth of the indenter pressed into the test block, and can automatically compensate for the surface factors of the workpiece Deformation of the pressure *> up to 50mm, instead of the pressing depth and the frame, the deformation of the workpiece conforms to the depth value

-The resolution of the depth measuring device is 0.01um, and the indentation depth measurement error is less than 0.05um

-The lead screw lifting loading system without traditional closed-loop control system, the probe stroke is executed by the double linear frictionless bearing, so there is almost no need to consider any aging and errors caused by the lead screw system (AFFRI*)



product manual

Affri system A new generation of hardness tester

The operator only needs one action to start the automatic program measurement without any pause: contacting the workpiece, preloading and main loading, indentation measurement, unloading, and releasing the workpiece. All test steps are completed with one button, completely eliminating operator error, thereby *> greatly increasing the accuracy and repeatability of the test.
Automatically touch the test sample, the AFFRI system can perform automatic contact with the test sample surface without the need to move the sample. Once in contact with the workpiece, the test system and the indenter immediately start to work, clamp the workpiece, apply a load, and then measure according to the Brinell, Rockwell or Vickers method.
Even during the measurement process, even if the test sample undergoes an axial deflection of 50mm, the system can still maintain the measurement*. This automatic compensation can maintain the* measurement results in the harsh test environment. (Automatically compensate the influence of the deformation of the workpiece and the frame under the large load on the measurement accuracy) The
external vibration source does not have any effect on the result. The sensor detects the frequency of 1000hz, and automatically compensates for the overload and load instability caused by the vibration.
Before loading, The test sample is automatically clamped and locked (clamping force 20 to 400 kgf).
AFFRI SYSTEM's fully automatic closed-loop load control system provides the highest precision load force, fully complying with ISO-JIS standards.
Built-in AFFRI system, even one test can achieve perfect and effective measurement.
The stability of accuracy can be maintained under any circumstances.
There is no need to adjust the level after installing the instrument.
Everyone can operate the instrument, even untrained people can use it well, as long as one key operation* can wait for the result.

All systems comply with CE regulations

All operations are simplified, including automatic test piece analysis

-Press the start button, the machine head will automatically move up to 50mm to the surface of the workpiece, and the whole test process is completely automatic

-Approaching the workpiece

-Clamp the workpiece

-Positioning surface

-Complete the entire test process and release the artifact
