QUALITIY CONTROL

RAW MATERIAL

We are very particular about grade and quality of raw material. We follow ASTM Standards and SEP-1520-98 Chart. We use raw material of the best manufacturer's who are internationally known and accepted. It is our habit to put enough efforts to check the quality of raw material 100% within our own premises and by the best instruments available in the world such as Carl ZEISS microscope model no AXIOVERT 100A having magnification upto 1000x originally imported from Germany.

HEAT TREATMENT

Reasons for Heat Treating

Steel is heated upto its hardening temperature and at that temperature material is held for a fixed time to soak the temperature then it is quenched in oil. Quenching is cooling the material rapidly from a temperature above the transformation temperature. After quenching the material is very hard and brittle. After that Cold Treatment is done to improve the microstructure further. To make the steel more ductile and to remove the internal stresses, it is tempered. Tempering consists of reheating the quenched material to a suitable temperature below the transformation temperature for an appropriate time and cooling back to room temperature.

METROLOGICAL CONTROL

In parallel to be particular about raw material we do take care of quality at each stage. A perfect combination of good metallurgy & metrology is the only way to get the optimum life of a bearing or component. Knowing the above we nourish both the part equally and continuously check the metrology by originally imported instruments from Rank Taylor Hobson UK i.e. Talyrond 262 & 131C and TalySurf FTS Intra2 Systems with Ultra Comprising Model No I-60 & Model No 50.
