摘要:
A wear-indicating metalworking fluid is provided that includes a lubricant base; and a wear-indicating agent. A method of determining wear in a metalworking fluid includes providing wear-indicating metalworking fluid that contains a lubricant base and a wear indicating agent; and observing the visual appearance of the metalworking fluid. A change in visual appearance of the metalworking fluid when compared to an unused metalworking fluid indicates wear of the metalworking fluid.

The invention provides a water-soluble metal-working oil agent, including a component A and a component B, wherein the component A is a mineral oil which has a characteristic temperature, as measured in accordance with JIS K2242, of 570° C. or higher, and the component B is at least one condensed fatty acid which is selected from a condensed fatty acid (1), produced through dehydration condensation of a hydroxycarboxylic acid, and a condensed fatty acid (2), produced through dehydration condensation of an alcoholic hydroxyl group of the condensed fatty acid (1) with a monovalent carboxylic acid, which has a characteristic temperature, as measured in accordance with JIS K2242, of 650° C. or higher. The agent can provide excellent workability with a hard-to-work material and can prolong tool life.

摘要:
A die release agent composition is provided that is used by being applied to a die used for the squeeze casting, low-pressure casting, or the like of a metal or a die used for die forging. The die release agent composition includes a mineral oil or a synthetic oil, a solid lubricant, a thermosetting resin, and a polymer compound. The die release agent composition is used by being applied to the inner surface of a die for casting or forging.
摘要:
The present invention relates to a method for reconditioning bearing lubricants that can be used in equipment for metal working, in which cooling lubricant that can be used in equipment for metal working is separated from the bearing lubricant. In addition the invention relates to a bearing lubricant for use in the method according to the invention.

Provided is a lubricating oil composition for round die rolling, which is obtained by blending a base oil with: (A) 0.5 to 40 mass % of a monoester having 13 to 48 carbon atoms (a-1) and/or 0.5 to 30 mass % of a fatty dicarboxylate having 13 to 34 carbon atoms (a-2); (B) 0.01 to 10 mass % of a thiadiazole compound; (C) 0.01 to 15 mass % of a thiophosphite; and (D) 0.01 to 5 mass % of a triazole compound. The lubricating oil composition for round die rolling shows excellent processing performance without using any chlorine-based compound, and is able to improve lubricity in a bearing to lengthen the life of the bearing.
摘要:
A system and a method for pretreating an aluminum assembly includes selecting a blank having a thin film pretreatment layer and a lubricant coating applied to a surface. The blank is formed to a desired shape and an adhesive is applied to a selected portion of the surface. A cleaner is applied to the assembly to remove the thin film pretreatment layer and the lubricant coating from the surface except at the selected portion and a zirconium oxide conversion coating is applied to the assembly before painting.
摘要:
Compositions related to a water-based lubricant fluid for aluminum cold rolling which is free from measurable particles or oil droplets which can be applied in field production. A single-phase lubricant fluid may include water-soluble polymers, lubricating additives, anti-rust additives, anti-oxidant additives, pH-adjust additives, or combinations thereof.
