AUTOMATIC HARDNESS TESTER FOR JOMINY METHOD IN COMPLIANCE WITH ASTM E18 AND ISO 6508 STANDARDS

Designed for Multiple Specimen Testing and Double Sized Surface Testing

Jominy - Rockwell - Superficial Rockwell - Brinell / Test loads from 3 to 187,5 kgf (29,45 to 1839 N)

CARACTERISTICS

• Designed for multiple specimen testing and double sized surface testing

• Single or multiple samples can be tested automatically, conforming to ASTM E-18 specification
• Optical imaging system.
• Panoramic camera with a 5X objective, for a clear recognition of the sample pattern starting origin. Independent for each sample
• Self automatic calibration cycle, conforming to ASTM E-18- ISO 6508 on three test block ranges (Hard, Medium & Soft)
• Standardized test patterns are stored in the integrated database to make the instrument easier to operate
• A customized test cycle can be created at anytime
• The automatic self validation of the instrument makes the user save time and optimize the use of the test block surface.

INNOVATIVE MEASURE

DAKO JOMINY AFFRI® System achieves the highest level of depth accuracy and measurement resolution available for Rockwell test. Motorized measuring head with 200 mm of vertical stroke for automatic movements and automatic contact with the test piece. Further 50 mm of vertical stroke for the indenter and the clamping hood

LOAD CELL & CLOSED LOOP TECHNOLOGY

Each load force is automatically programmed and controlled assuring perfect linearity in every range eliminating the problems associated with traditional dead weight system testers. The test is not affected by any external sources of deflection, misalignment or vibration. The AFFRI system can also operate in an inclined position.

AUTOMATIC CALIBRATION

Self automatic calibration cycle, conforming to ASTM E-18- ISO 6508. Three test blocks ( Hard, Medium & Soft) ranges. It will retain the test block locations, move to each test block, indent and self calibrate. It will also automatically linearize your working scale with the calibration test block results.

MUTI-SAMPLES TEST CYCLE

Single or multiple sample test pieces, can be tested automatically, conforming to ASTM E-18 specification. Multiple sample facing testing included.

OPTICAL IMAGING SYSTEM

Panoramic camera with a 5X objective, for a clear sample pattern starting origin. Independent for each sample.

HIGH PRECISION

High accuracy motorized 
table with 0.5 μm step for automatic movements on X and Y axis within an area of more than 200x400 mm.

SOFTWARE

Standardized test patterns are stored, in the on board database, for ease of instrument operation. A customized test cycle can be created at anytime, thus saving repeative patterns.
