Abstract

Disclosed is a metalworking oil composition containing: at least one base oil (A) selected from a mineral oil and a synthetic oil; sulfurized oils and fats (B) having a kinematic viscosity at 40° C. of 60 mm 2 /s or more and 1,600 mm 2 /s or less; and a polymer (C) of an unsaturated fatty acid having a carbon number of 10 or more.

First claim

1 . A metalworking oil composition, comprising:
at least one base oil (A) selected from a mineral oil and a synthetic oil; sulfurized oils and fats (B) having a kinematic viscosity at 40° C. of 60 mm 2 /s or more and 1,600 mm 2 /s or less; and a polymer (C) of an unsaturated fatty acid having a carbon number of 10 or more.

2 . The metalworking oil composition according to claim 1 , wherein a mass ratio of the sulfurized oils and fats (B) and the polymer (C) of an unsaturated fatty acid [(B)/(C)] is 0.1 or more and 30 or less.

3 . The metalworking oil composition according to claim 1 , wherein the content of the sulfurized oils and fats (B) is 1 mass % or more and 30 mass % or less on a basis of the total amount of the composition.

4 . The metalworking oil composition according to claim 1 , wherein the polymer (C) of an unsaturated fatty acid is at least one dehydrated condensate of an unsaturated fatty acid having a carbon number of 10 or more and 24 or less.

5 . The metalworking oil composition according to claim 4 , wherein the unsaturated fatty acid having a carbon number of 10 or more and 24 or less is at least one selected from the group consisting of ricinoleic acid, oleic acid, and linoleic acid.

6 . The metalworking oil composition according to claim 1 , wherein the content of the polymer (C) of an unsaturated fatty acid is 0.2 mass % or more and 20 mass % or less on a basis of the total amount of the composition.

7 . The metalworking oil composition according to claim 1 , wherein a kinematic viscosity at 40° C. of the polymer (C) of an unsaturated fatty acid is 100 mm 2 /s or more and 1,400 mm 2 /s or less.

8 . The metalworking oil composition according to claim 1 , further comprising an unsaturated fatty acid.

9 . The metalworking oil composition according to claim 1 , wherein a kinematic viscosity at 40° C. thereof is 3 mm 2 /s or more and 60 mm 2 /s or less.

10 . The metalworking oil composition according to claim 1 , which is adapted to function as a metalworking oil composition for cutting machining or grinding machining.

11 . The metalworking oil composition according to claim 1 , which is adapted to function as a metalworking oil composition for machining of at least one selected from a nickel-base alloy, a titanium alloy, and an iron-based material.

12 . A metalworking method, the method comprising machining a metal in contact with the metalworking oil composition according to claim 1 .

13 . The metalworking method according to claim 12 , which is cutting machining.

14 . The metalworking method according to claim 12 , wherein the metal is at least one selected from a nickel-base alloy, a titanium alloy, and an iron-based material.
