Problems solved by technology

[0003] At present, most of the ultra-finishing processes use kerosene or kerosene mixed with mechanical oil as the cooling and lubricating medium, which volatilizes seriously during the processing and is harmful to operators and the environment.
At the same time, simply using kerosene or kerosene mixed with mechanical oil as the cooling medium will cause insufficient lubrication performance during processing, thereby reducing the machining accuracy of the workpiece and substandard surface roughness, etc.; and cannot provide effective anti-rust and anti-corrosion for the workpiece between processes and other performance requirements, and even lead to blackening of the workpiece processing end surface, unable to meet customer requirements

preparation example Construction

[0039] A preparation method of environment-friendly superfine grinding oil, comprising the steps of:

[0040] 1) Each component is measured separately according to the proportioning ratio for use;

[0041] 2) Put the mineral base oil into the blending kettle, stir and heat up to 70-80°C;

[0042] 3) Add antioxidant and stir for 20-30 minutes;

[0043] 4) After cooling down to 50-60°C, add ester base oil, extreme pressure anti-wear agent, metal deactivator, oil mist inhibitor and anti-foaming agent in sequence, and stir each of the above components for 20 ~30min until completely dissolved, then add the next component;

[0044] 5) After all the components are put in, keep the temperature at 50-60°C and stir for more than 1 hour;

[0045] 6) Filter with a bag filter with a precision of 3 μm, pack and store.

Abstract

The invention relates to environmentally-friendly super-finishing grinding oil and a preparation method thereof. The environmentally-friendly super-finishing grinding oil is prepared from, by weight, 5.0%-10.0% of ester base oil, 3.0%-5.0% of an extreme-pressure and anti-wear agent, 0.5%-1.0% of an antioxygen, 0.05%-0.1% of a metal desactivation agent, 0.5%-1.0% of an oil mist inhibitor, 0.01%-0.05% of an anti-foaming agent and mineral base oil balance. The sum of the percentages of the above components is 100%. The environmentally-friendly super-finishing grinding oil has high lubrification, cooling, rust protection and corrosion protection performances; meanwhile, heavy metals, chlorine and low oil mist do not exist in the environmentally-friendly super-finishing grinding oil, so that the environmental-friendly super-finishing grinding oil is harmless to an operator and the environment.

Description

technical field [0001] The invention relates to a grinding oil for superfinishing, in particular to an environment-friendly superfine grinding oil and a preparation method thereof. Background technique [0002] Superfinishing is mainly used to process the outer circle, inner circle, plane, groove surface and spherical surface of crankshafts, rolls, bearing rings and various precision parts. The machining allowance is only a few microns. Compared with grinding, superfinishing can Within a few seconds to tens of seconds, the surface roughness of the workpiece is improved from Ra0.63-0.16 microns to Ra0.08-0.01 microns, and can effectively remove the defects such as vibration marks, ripples, and spirals produced by grinding. And the peaks and metamorphic layers that are extremely easy to wear, etc., thereby greatly improving the service life of the workpiece. [0003] At present, most of the ultra-finishing processes use kerosene or kerosene mixed with mechanical oil as the co...
