Abstract:
SUMMARY
The investigation carried out into surface grinding
Stayblade shows that this material presents severe conditions
to the grinding wheel, and the grinding wheel face is broken
down fiarly quickly.
The method described in C of A Note 38 for wheel and
coolant selection and development enabled the total wheel face
life to be improved from 0.105 cubic ins. to approximately
10.00 cubic ins, per redress with acceptable surface finish.
The use of soluble typos of coolants would appear to
be much less efficient than cutting or grinding oil coolants and
the following combinations were found best:-
Wheel:- Carborundum 7.D.A.60 I 5 IN BILT.
Coolant:- Manchester Oil Refinery DOLPHIN MC OIL.
Wheel life is 3.5 cubic ins. per redress for 7 ins. dia. by 1 in.
wide wheel.
The addition of 5% Wynns friction proofing fluid showed
200% increase in wheel face life with acceptable surface finish.
