Incoming Inspection

Internal Soundness Test

Samples are cut across section ,polished & etched in 50% hot HCL for 15-20 minutes .Inspection for Piping Porosity Macro Inclusions Hair Line crack segregations etc on C/S surface

Macro Structure

Samples to be taken as per Sampling Plan for Upsetting.Cut Pcs are forged at forging temperature to see for Surface Cracks .

SEAMS UPTO 0.1 Depth only accepted

Chemical Composition checking by wet analysis

Inclusion Rating.
Checked as per IS-4163 and should
not exceed 3A,3B,3C,3D, in thick & thin series .

Grain Size
One sample per heat, in the range of ASTM 5-8 for fine gain steels at x100 upset sample is normalized at normalizing temperature and the size of the Pearlite grains are compared with standard chart for actual grain size determination

Hardness
Upset normalized pieces are checked for the hardness to confirm whether normalized hardness is coming well within the specified limits

CAD / CAM Facility
CAD / CAM DEPARTMENT All Customer Drawings are studied In Auto CAD 2000 and then model simulation is done in Unigraphix NX 4.0 and accordingly Tool Path Generation is transferred to Vertical Machining Center in Tool Room Via LAN	VERTICAL MACHINING CENTER HAAS VF-2 15000 RPM Unigraphix NX4
