Vickers WIKI JS 

WIKI JS


Automatic Hardness tester for micro and macro Vickers, Knoop, Brinell and Rockwell test methods. WIKI JS is the top-of-the-line of automation and accuracy for Vickers and Knoop hardness measurements in compliance with ASTM and ISO hardness standards. It is a fully motorized system for Case Hardness Depth test (CHD) on single or multiple samples in automatic cycle. Everything is automated, freeing users for other tasks and minimizing subjectivity associated with human intervention. Just map-out indentation traverses where they are required, set the load and press START, the hardness tester intelligently follows the predefined patterns, indents the sample, focuses when needed, measures, and generates data dynamically. Load forces are applied through load cells and electronically controlled in “Closed Loop” (Pat. AFFRI) with a frequency of 1 khz, assuring perfect linearity in every range, even on very low loads. For micro-macro Vickers and CHD case depth tests on all metals: iron, steel, tempered steel, cast iron, brass, aluminium, copper and metal alloys. Heat treatment, hardening, nitriding, cementation and hardfacing. Knoop test on ceramic and glass materials.

MOTORIZED HEAD AND AUTOMATIC TEST CYCLES


The measuring head approaches the specimen and begins the test, following every predefined pattern and performing each indentation, no matter the amount. Results are listed along with the corresponding indentation image, statistics and CHD charts.

CLOSED LOOP (PAT. AFFRI)


Load forces are applied through load cells and controlled in “Closed Loop” with a frequency of 1 khz, assuring perfect linearity in every range. Results are not affected by any structural deflection, misalignment, vibration or problems associated with dead weight systems on traditional testers

MOTORIZED TURRET


Horizontally rotating turret with four slots for magnification lenses and two for indenters. All optical microscope objectives can be pre-installed and combined with indenters for every Vickers and Knoop hardness scales.

X/Y MOTORIZED TABLE


With an accuracy of +/- 0.5 μm steps, reference points for patterns indentations can be positioned precisely where they are required. The table allows automatic multi-indentation test cycles on multiple samples with perfect positioning on the entire area.

INDENTER STROKE


WIKI JS can perform reliable tests even on multilevel or misaligned sample surfaces.

AUTOFOCUS AND IMAGE CLEANING


With software controlled focus, image cleaning, shading correction and DC regulated light source, reproducible results are obtained regardless of the number of indents measured. From perfectly polished to rough and etched samples, the auto-detection capabilities of WIKI JS allow measurements on a variety of sample surfaces.
