view source
US Patent:

42538505, Mar 3, 1981
Filed:

Aug 17, 1979
Appl. No.:

6/067710
Inventors:

Charles V. Rue - Petersham MA
Kesh S. Narayanan - Holden MA
Assignee:

Norton Company - Worcester MA
International Classification:

B24B 100
C08J 514
US Classification:

51298
Abstract:

Organic bonded abrasive bodies such as snagging wheels and wheel segments for conditioning billets, slabs, and castings have abrading portions with 0 to 8% pores by volume, a low abrasive content of from 24 to 45% by volume of 4 to 36 grit size abrasive, substantially constant volume of a thermosetting resin of from 18 to 24% by volume and a high content of filler material constituting from 29% to 56% by volume of the body and wherein at least 80% by volume of the filler material is inorganic material.

Filed:

Aug 19, 1985
Appl. No.:

6/767204
Inventors:

Kesh S. Narayanan - Holden MA
Suresh S. Vagarali - Shrewsbury MA
Brian E. Swanson - Northborough MA
Assignee:

Norton Company - Worcester MA
International Classification:

B24D 302
US Classification:

51309
Abstract:

A combination of fused alumina grits with sintered gel alumina abrasive grits is shown to be more effective than either abrasive alone in cutting steel bars with bonded abrasive wheels at intermediate cutting speeds.

US Patent:

46829881, Jul 28, 1987
Filed:

Oct 25, 1983
Appl. No.:

6/545321
Inventors:

Kesh S. Narayanan - Holden MA
Gordon E. Hickory - Upton MA
Assignee:

Norton Company - Worcester MA
International Classification:

C09K 314
US Classification:

51298
Abstract:

A grinding wheel is described which is bonded with a phenol formaldehyde resin based bond containing hexamethylenetetramine as the curing agent. The wheels are made by first wetting the abrasive with furfural in varying quantities relative to the amount of hexamethylenetetramine in the phenol formaldehyde resin. Different amounts of the curing agent require different specific amounts of furfural to produce optimum properties in the finished grinding wheel.

46093818, Sep 2, 1986
Filed:

Dec 13, 1984
Appl. No.:

6/681052
Inventors:

Kesh S. Narayanan - Holden MA
Suresh S. Vagarali - Shrewsbury MA
Assignee:

Norton Company - Worcester MA
International Classification:

C09K 314
US Classification:

51298
Abstract:

This invention relates to organically bonded abrasive articles that include grinding aids. It has been determined that when known grinding aids such as alkali metal sulphates and alkali metal chlorides are cofused in about eutectic proportions and added to thermoset resin bonded abrasive articles in the form of finely crushed particles having an approximate eutectic composition that an improved abrasive article results.
