Abstract
Abstract An electrodeposited grindstone obtained by embedding abrasive grains in a nickel plated bearing layer due to electrodeposition process and a nickel-phosphorus alloy bearing layer due to chemical plating process formed successively on a grinding part surface of a grindstone base metal. An electrodeposited grindstone obtained by forming a thin plated layer by electrodeposition process on said electrodeposited grindstone which underwent a heat treatment and on the surface of the nickel-phosphorus alloy bearing layer.

Claim 2
Dependent Claim
62 words
(2) An electrodeposited grindstone characterized in that it is obtained by subjecting to a heat treatment an electrodeposited grindstone obtained by forming successively a nickel plated bearing layer due to electrodeposition process and a nickel-phosphorus alloy bearing layer due to chemical plating process on a grinding part surface of a grindstone base metal, formed for letting these layers embed hard abrasive grains.
Claim 3
Dependent Claim

(3) An electrodeposited grindstone characterized in that hard abrasive grains are embedded in a nickel plated bearing layer due to electrodeposition process and a nickel-phosphorus alloy bearing layer due to chemical plating process formed successively, after giving a heat treatment by forming successively a nickel plated coating due to electrodeposition process and a nickel-phosphorus alloy plated coating due to chemical plating process on a grinding part surface of a grindstone base metal.
Claim 4
Dependent Claim
111 words
(4) An electrodeposited grindstone formed by embedding hard abrasive grains such as cubic system boron nitride abrasive grains and diamond abrasive grains on a grinding part surface of a grindstone base metal, characterized in that it is obtained by embedding the abrasive grains in a nickel plated bearing layer due to electrodeposition process and a nickel-phosphorus alloy bearing layer due to chemical plating process formed in succession, after giving a surface treatment to said grinding part surface by forming successively a nickel plated coating due to electrodeposition process and a nickel-phosphorus alloy plated coating due to chemical plating process, and finally subjecting the electrodeposited grindstone thus obtained to a heat treatment.
Claim 5
Dependent Claim
83 words
(5) A high strength electrodeposited grindstone, being an electrodeposited grindstone obtained by dispersedly fixing hard abrasive grains such as cubic system boron nitride abrasive grains and diamond abrasive grains on a grindstone base metal, having bearing layers formed by chemical plating process, either singly or in combination with electroplating process, and the electroplated layers being subjected to a heat treatment for enhancing the strength and abrasion resistance thereof, a characterized in that a thin electroplated layer is formed on said chemically plated layer.
