Embodiment Construction

[0017] Preferred embodiments of the present invention will be described in detail below.

[0018] Table 1 Components and mass fractions of each embodiment of the present invention, PB value and PD value of each embodiment:

[0019]

[0020] The index to measure the extreme pressure lubrication performance of gravity cutting oil is usually "Determination of Lubricant Bearing Capacity (Four-Ball Method)" (GB / T 3142-1982), and the maximum non-seizing load PB of gravity cutting oil is measured on a four-ball friction and wear tester Value (in N) and sintering load PD value (in N), with PB value not less than 980N and PD value not less than 7840N as the lubricity control index of gravity cutting oil. It can be seen from Table 1 that the PB value and PD value of each embodiment of the present invention can reach the control index, indicating that the oil-soluble gravity cutting oil of the present invention can meet the severe requirements of gravity cutting.

Abstract

The invention discloses oil-soluble gravity cutting oil. The oil-soluble gravity cutting oil comprises the following components in percentage by weight: 88.0-94.0 percent of base oil, 3.0-5.0 percent of high-alkaline calcium sulfonate extreme pressure anti-wear additive, 2.0-4.0 percent of vulcanized fatty acid ester extreme pressure anti-wear additive and 1.0-3.0 percent of chlorcosane extreme pressure anti-wear additive. According to the oil-soluble gravity cutting oil disclosed by the invention, the high-alkaline calcium sulfonate extreme pressure anti-wear additive, the vulcanized fatty acid ester extreme pressure anti-wear additive and the chlorcosane extreme pressure anti-wear additive are added; and a compound formula of three additives can realize the lubrication from low temperature to high temperature and from low load to high load born by gravity cutting. Therefore, the oil-soluble gravity cutting oil disclosed by the invention can meet the harsh requirement of gravity cutting processing.

Description

technical field [0001] The invention belongs to the technical field of lubricating oil, and in particular relates to an oil-soluble gravity cutting oil. Background technique [0002] Cutting oil is used for lubrication and cooling in metal processing such as cutting, broaching, drilling, tapping and grinding. Gravity cutting is a form of cutting with high temperature and pressure in metal processing. The cutting oil must be Only high extreme pressure lubrication performance and cooling capacity can meet the requirements of this processing method. Therefore, the conventional cutting oil only uses the composite formulation of sulfur-containing extreme pressure anti-wear additives and chlorine-containing extreme pressure anti-wear additives, which cannot meet the severe requirements of gravity cutting. Contents of the invention [0003] In view of this, the present invention provides an oil-soluble gravity cutting oil, which can meet the severe requirements of gravity cuttin...
