ISOTHERMAL QUENCHING STEEL 100Cr6
Steels for rolling bearings are important in the world production of special steels. They are used for the production of rolling bodies and rings. Since these are very responsible parts in machine construction, high-quality standards are required for these steels. The service life of rolling bearings, in addition to working conditions also depends ...

THE INFLUENCE OF EXPANDED MEASUREMENT UNCERTAINTY IN THE STATEMENT OF CONFORMITY FOR HAND TORQUE TOOLS CALIBRATION
The BAS EN ISO/IEC 17025 standard gives the laboratory the opportunity to accredit the statement of conformity. The statement of conformity is provided in accordance with the specification, standard or costumer requirement. Prior to issuing the statement of conformity, the accredited laboratory, in cooperation with the costumer, must document the d...

EFFECT OF MIXING OF COOLING MEDIA ON MICROSTRUCTURE AND HARDNESS OF STEEL 23MnB4
Steel cooling is an important technological operation because the final microstructure of the steel,and therefore its properties, depends on the cooling rate. The speed of steel cooling depends onnumerous factors, one of which is the movement of the cooling media. This paper presents theresults of testing the influence of mixing the cooling media o...

ESTIMATION OF THE CALIBRATION MEASUREMENT CAPABILITY OF MECHANICAL CALIBRATION LABORATORY
The calibration measurement capability - CMC is defined as the smallest uncertainty that a laboratory can achieve within its powers when carried out more or less daily calibration of nearly ideal measurement standards intended to define, generate, keep or renew units of that size, or one or more of its value, or when carried out more...

MATERIAL STRENGTHENING IN FORMING FINAL TUBULAR PRODUCT FROM AL 99.5% BY FORWARD COLD FLOW FORMING
Final product of the cold forming process gain many advantages that are mostly produced by strengthening of the material in the process. Those advantages are primarily explained as improving mechanical characteristic of the work material. Forward cold flow forming is among those processes and it is mostly related to (forming) shaping...
