Prova Rockwell Spessori minimi controllabili ISO 6508 ASTM E18

Il calcolo è peraltro molto semplice
esempio
Scala HRA   valore riscontrato o del campione  50 HRA  
Scala Rockwell =0,2mm divisa in 100 parti 1 punto corrisponde a 0,002 mm


Scala  100 - 50 (Valore del campione) = 50
50x0,002 (un punto della scala Rokwell)   =  0,010mm
0,010mm  per 10 volte influenza della penenetrazione =0,1mm
=0,1 mm spessore minimo del campione
penetrazione del diamante nel campione






Conversioni da HRC a HRA a HRD a HR15N a HR30N a HR45N

OCELOT Digital measuring system Brinell and Vickers impressions, in accordance with regulations UNI EN ISO 6506 UNI EN ISO 6507 1-2 1-2 ASTM E384 ASTM E10 The system consists of a tablet with keyboard dedicated and of a suitably modified digital caliper for the correct measurement of impressions is that Vickers Brinell. Ocelot program for the measurement and analysis of the Brinell and Vickers: The Program allows: The calibration of six different targets (also calibration at several points of the same objective to make up, if either the optical aberration). The selection of all loads Brinell and Vickers between 1 and 3000 (Kp) Load pre set and modify them. The transformation of the values ​​in HRC or N / mm2 The selection of all the Brinell penetrators from 1, 2,5 5 and 10 mm Bols diameters The choice of working in normal mode or statistical analysis Item analysis with minimum settings, Max, Everagea. Chart histogram or scatter. Protocol in PDF format et/or Excels The archive of the results, and export via USB port to PDF and Excel. The test protocol with company data and customer with lotto drawing and notes. The control of the test data and test chart, gauge control, power status control. Softkey Guidance. Shutting down the tablet. modified digital caliper: Sylvac gauge with RS232 USB output with beaks changed from two boxes with ground floor at 15 degrees for proper alignment and reading of tread summit without optical errors or parallax or collimation. Single initial zero with translation on guide around the gauge in order to measure at any position of the screen from 0 to 120 mm Guide ITEM aluminum with grooves for fixing in place of the old straight edge measurement. connecting cable and USB interface of 2 meters length. Tablet 10 " Tablet touch screen 10-inch dedicated, thus precludes tampering, as it can only and exclusively be used with the "Oceot" program. for external power supply and charging internal battery Standard USB socket pull-out keyboard. external power supply Support for Tablet 10 " Made of stainless steel, it can be applied to the side of the footprint projection screen or leaning against the table top      For the installation of the system do not require additions or modifications to the device in use, just remove the old ruler and insert the digital gauge. Prompt delivery (max 15 days from the date your order) delivered ex Mailand Italy Payment R.D. warranty 12 months warranty excluding damages for malpractice Offer valid 30 days. INSTALLATION AND INSTRUCTIONS FOR THE OPERATOR If necessary installation and operator training will be carried out by our technical staff at the following rates: Euro 60,00 each hour trip. Kilometers Euro 0.60 each. Euro 66,00 hours each job.
(Caliber installation and tablet support as calibration and operator training) Possible, only when specifically requested, optical cleaning and tuning the durometer to the above rates

Prova Brinell Spessore minimo controllabile

Per le prove Brinell ho diviso in due tabelle
la prima per acciai e ghise 
la seconda per alluminio e leghe leggere 

Per i bordi vanno mantenute le stesse quote pensando di avere dal centro dell'impronta al bordo la medesima dimensione,

 Per Acciai e Ghise




Per Allumini e leghe leggere
