Lubricant composition for cutting machining of ordinary carbon structure steel gear

Abstract

The invention discloses lubricant composition for cutting machining of an ordinary carbon structure steel gear. No.15 total loss system oil is adopted as base oil and matched with multiple composite additives including an antioxidant, an oily agent, a friction modifier, an extreme pressure agent, an antiwear agent, an antirust agent, an anti-foaming agent and an oxidation and corrosion inhibitor. The composition is good in cooling performance, lubricating property, cleaning performance and diffusibility and high in chip removal capacity, can reduce phenomena such as accumulated burl, scratching and bruising produced during machining and has the advantages of resisting wear, reducing friction and preventing rust.

Description

technical field [0001] The invention belongs to the field of cutting processing of carbon steel gears, and in particular relates to a lubricant composition for cutting processing of ordinary carbon structural steel gears. Background technique [0002] Ordinary carbon structural steel is also called ordinary carbon steel. The carbon content is 0.06-0.22%, and less than 0.25% is the most commonly used. Belonging to low-carbon steel, each metal grade indicates the lowest yield point of the steel when the thickness is less than 16mm. my country and some countries divide ordinary carbon steel into three categories according to the delivery guarantee conditions: Class A steel (Class A steel), which only guarantees mechanical properties, but does not guarantee chemical composition, Class B steel (Class B steel), Only the chemical composition is guaranteed, but the mechanical properties are not guaranteed; special steel (C-type steel) not only guarantees the chemical composition, b...

Problems solved by technology

[0005] The working conditions of cutting oil and ordinary lubricating oil are different. Ordinary lubricating oil is between the constant friction surfaces that move repeatedly. Although there is a lot of pressure, it is easy to form a lubricating oil film.
