Fine Spavy Associates & Engineers Pvt. Ltd.
 

Micro Vickers Hardness Testing Machines ( Model : FMV-1 )

 
Suitable for finish components like thin sheets, fine wires, etc. Watch parts like springs, pivot bearings, gears, cutting edge of Razor blades, drills, file teeth, etc. Metallic foils, surgical needles, pen points & so on.
To determine hardness on - surface coatings (like electroplating, etc.), extremely thin case hardened parts, anodized castings of alluminium, shot blasted or rolled faces, etc.
A range of test loads can be used to suit particular application. Test loads from 10 grams to 1000 grams.
Magnifications - 125X, 250X & 625X available.
X-Y stage is provided with least count of 0.01mm, which can move the job as per the requirements.
A precision Diamond  Indentor (136° pyramid) is used to make sharp indentations on the specimens / samples.
Maximum Test height  x Throat : 115 x 70 mm.
Load accuracy well within ± 1% of nominal load value. Machine conforms to IS:1754.
Computerized model is available .Computerized model has built in CCD and suitable advanced software. Hardness will be displayed on computer monitor automatically. Results printout can be taken.
Extra (Optional) accessories like – Knoop Indentor, Knoop test block, Precision vice, Thin specimen holding device, V-shape anvil, Vertical & Horizontal fine specimen holding device, Rotary table, etc. are  available.
