Common brass alloy cutting processing technic lubricant composition

Abstract

The invention discloses a common brass alloy cutting processing technic lubricant composition. No.7 total loss system oil is used as base oil, and multiple compound additives are matched. The composition comprises an antioxidant, a metal deactivator, an oiliness agent, a friction improver, an extreme pressure agent, an antioxidant, an anti-foaming agent, a demulsifying agent, an anti-rust agent, a cooling accelerant and a dispersing agent. The composition provided by the invention has good cooling property, lubricating property, bearing capacity, anti-wear property, vibration reduction, cleaning and chip removal functions, anti-rust property, oxidation and corrosion inhibiting property, defoaming property and good decomposition resistance, is low in smell, low in oil mist, and nonirritant, and has good intermiscibility with machine tool paint.

Description

technical field [0001] The invention discloses a common brass alloy cutting process lubricant composition and belongs to the field of metal processing process lubricants. Background technique [0002] Ordinary brass is an alloy composed of copper and zinc. When the zinc content is less than 35%, zinc can dissolve in copper to form single-phase a, which is called single-phase brass, has good plasticity, and is suitable for hot and cold press processing. When the zinc content is 36% to 46%, there is a single phase and a β solid solution based on copper and zinc, which is called dual-phase brass. The β phase reduces the plasticity of brass and increases the tensile strength, which is only suitable for brass. Hot press processing. [0003] There are many metal processing methods, but cutting is always the most common and widely used one. Metal cutting is an important mechanical processing method, which can be divided into two categories according to the type of cutting tools ...

AI Technical Summary

Problems solved by technology

[0004] 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.
