Abstract

A method for producing an aluminum bar includes at least one machining step in which an aluminum bar-shaped work is machined while supplying a machining fluid containing oil to produce a machined aluminum bar-work, and a cleaning step in which the machined aluminum bar-shaped work is cleaned using a cleaning fluid to produce a cleaned machined aluminum bar-shaped work. The cleaning step is performed so that the oil contained in the machining fluid remains on a surface of the cleaned machined aluminum bar-shaped work in a range of 5 μg/cm 2 to 20 μg/cm 2 .

First claim

The invention claimed is:

1. A method for producing an aluminum bar, the method comprising:
at least one machining step in which an aluminum bar-shaped work is machined while supplying a machining fluid containing oil to produce a machined aluminum bar-shaped work; and
a cleaning step in which the machined aluminum bar-shaped work is cleaned using a cleaning fluid to produce a cleaned machined aluminum bar-shaped work so that the oil contained in the machining fluid remains on a surface of the cleaned machined aluminum bar-shaped work in a range of 5 μg/cm 2 to 20 μg/cm 2 .

2. The method for producing an aluminum bar as recited in claim 1 , wherein the aluminum bar-shaped work is an aluminum continuously cast bar.

3. The method for producing an aluminum bar as recited in claim 1 , wherein the at least one machining step includes a step of peeling a surface of the aluminum bar-shaped work.

4. The method for producing an aluminum bar as recited in claim 1 , wherein the at least one machining step includes a step of cutting the aluminum bar-shaped work.

5. The method for producing an aluminum bar as recited in claim 1 , wherein the at least one machining step includes a step of correcting a curvature of the aluminum bar-shaped work.

6. The method for producing an aluminum bar as recited in claim 1 ,
wherein the at least one machining step includes any two or more steps selected from a group consisting of
(a) a step of peeling a surface of the aluminum bar-shaped work,
(b) a step of cutting the aluminum bar-shaped work, and
(C) a step of correcting a curvature of the aluminum bar-shaped work.

7. The method for producing an aluminum bar as recited in claim 1 , wherein the cleaning fluid is water having a pH of 5.5 to 7.5.

8. The method for producing an aluminum bar as recited in claim 1 , wherein the machining fluid is a water-soluble cutting fluid or a water-insoluble cutting fluid.

9. A method for producing an aluminum bar, the method comprising:
producing a machined aluminum bar-shaped work by peeling a surface of an aluminum bar-shaped work using a peeling device;
supplying a machining fluid containing oil during the producing of the machined aluminum bar-shaped work in a location near the peeling device; and
cleaning the machined aluminum bar-shaped work to produce the aluminum bar using a cleaning fluid in a cleaning tank so that the oil contained in the machining fluid remains on a surface of the aluminum bar within a range of about 5 μg/cm 2 to about 20 μg/cm 2 .

10. The method for producing an aluminum bar as recited in claim 9 , further comprising packaging the aluminum bar with the oil on the surface.

11. The method for producing an aluminum bar as recited in claim 9 , wherein the cleaning of the machined aluminum bar-shaped work is performed by providing the cleaning fluid at a temperature of about 15° C. (degrees Celsius) to about 95° C. (degrees Celsius).

12. The method for producing an aluminum bar as recited in claim 11 , wherein the cleaning of the machined aluminum bar-shaped work is performed by providing the cleaning fluid at a temperature of about 70° C. (degrees Celsius) to about 95° C. (degrees Celsius).
