CONTROL PROCESS:
(An ISO 9001:2000)
Quality has
always been integrated parts of corporation culture and ever afford
is made ensure that the customer get best quality material. We have
inducted skilled employees at all level to bring their experience
and executive in to the manufacturing of bearing.
During production
the at most care is taken in each operation of grinding to maintain
case tolerance. We conduct 100 % checking of raw material and our
in process.
For checking
geometrical parameters such as concentrate, paramecium and circular
run out have all testing equipment's. Tolerance on our bearings
confirm to ISI standards. Raw materials used for outer ring, inner
ring and roller are SAE - 52100 / EN- 31 as per IS 4398. Our inspection
shortly from the beginning i.e. when outer and inner forged turned
rings are received they are checked with the help of master rings
and comparator. Then they are hardening process. They are checked
for hardness crack and ovality. Hardness required to 58 to 62 HRC
when the grinding begins first of all face is grinded on rotary
surface grinder. The material remained is 0.2 to 0.3mm. . Here size
face paralisum surface finished in faces, flatness and visual parameter
are checked with the help of comparators and masters.
In the same
way of outer and inner rings are grinded and for quality they are
checked in the same procedure mentioned above. Finally the tracks
are honed with honing stick. Here material remained is maximum 5
microns. After final washed rings goes to assembly.
