Micro IRHD Laser Revolution

Characteristics of the Instrument

The instruments is supplied with laser centring device and motor-controlled sample holding disk for the displacement of the parts to be measured.

The sample holding disk moves each test pieces under the laser centring tool and then places the optimal test point of the part under the micro-irhd testing unit.

The positioning and hardness measuring operations are performed automatically for all the parts placed on the sample holding disk across the laser reading line without intervention of the operator.

The instrument is conforming to ISO 48, ASTM 1415, DIN 53 519-1/2 standards.

Apprications and Use of the instrument

The instrument permits to perform the serial measure of micro-irhd hardness of o-rings and small parts eliminating the human influence in the sample positioning.

The instrument is useful for:

- Product approval or Quality Control tests which require the repeating of the tests on statistical basis

- Mould approval tests

- Process capability analysis

- Testing of small parts difficult to be centered manually

O-ring or small parts with thickness between 1 and 20 mm can be tested.

The laser testing process can be stopped to perform tests with standard samples.

USE OF THE INSTRUMENT

To perform the test you simply need to:

- place the parts to be tested across the test line of the sample holding disk

- insert the identification of the product

- press start

- when the complete rotation of the disk has been performed and all the samples have been tested, you can print the test report and save the test results.

MEASURE OF MICRO-IRHD HARDNESS ON PIECES WITH NON SYMMETRICAL SHAPE

The software for the control of the instrument includes a ‘Scan'' function which permits to record the laser reading of the profile of a piece and to define the position where the test has to be made.

The test setup for each product is stored and is automatically re-used when the same product is tested again.

EXECUTION OF TESTS ON DIFFERENT PRODUCTS

The sample-holding disk is divided in 4 sectors.

According to your needs, you can use all the sectors to test the same product or you can place different kind of pieces in each sector.

At the beginning of the test you can enter the identification for the products placed in each sector. In this way each result will be saved or printed with correct identification.

CALIBRATION

The instrument is supplied with ACCREDIA calibration certificate. The certificate is issued by Gibitre ISO-17025-Accredeted laboratory

Technology of Micro-IRHD device

The micro-irhd testing units produced by Gibitre measure the force applied to the sample using a load cell. This technology, widely used for the hardness testers for metals, permits to eliminate the effect of friction in the application of the force and improves the test repeatability.

Characteristics of the laser centring device and of the sample-positioning system

The laser sensor used is class 2 type and has 0.001 reading resolution.

The sample positioning disk permits to set the position of the test piece with 0.005 mm accuracy.

The combination of accurate measuring and sample positioning devices ensures a very high repeatability of the results obtained even when very small parts are tested.
