What is the difference between microemulsion cutting fluid and water-based cutting fluid? How to choose?
December 01, 2021
Cutting fluid is an industrial liquid used in the process of metal cutting and grinding to cool and lubricate tools and processed parts. It is mainly made up of a variety of super-functional additives through scientific compounding. It has good cooling Performance, lubrication performance, anti-rust performance, degreasing and cleaning function, anti-corrosion function, easy dilution and other characteristics.
The cutting fluid effectively suppresses the problems of traditional soap-based emulsions that are easy to smell in summer, difficult to dilute in winter, and have poor anti-rust effects. However, microemulsion cutting fluid and water-based cutting fluid are the most common in life, and their composition, performance and application fields are not the same. Let's take a look at them in detail below. 1. Ingredients 1.1 Microemulsion cutting fluid refers to a mixture of oil and water of diluent oil droplets with a diameter of less than 1m. 1.2 Water-based cutting fluids can be divided into emulsions, semi-synthetic cutting fluids and fully synthetic cutting fluids; the diluent of the emulsion is milky white in appearance; the diluent of the semi-synthetic fluid is usually translucent, and some are milky white. ; The diluent of fully synthetic liquid is usually completely transparent such as water or slightly colored. 2. Performance 2.1 The performance of microemulsion cutting fluid is as follows (1) Good lubrication performance can reduce the surface roughness of the workpiece, improve the accuracy of the workpiece, and extend the service life of the tool and die. (2) Good cooling performance, can effectively and quickly take away the heat generated during the machining of the tool and workpiece, reduce the temperature of the cutting zone, reduce the deformation of the workpiece, and maintain the hardness and size of the tool. (3) Good cleaning performance, reduce the adhesion of fine chips and powder to facilitate cleaning, and can effectively wash away the chips and dust. (4) Good anti-rust performance, no corrosion to tool materials, tool materials, various metal pipes and coating paint on the surface of machine tools. (5) Good storage stability, anti-bacterial and anti-corrosion ability, resistance to hard water, and long service life. 2.2 The performance of water-based cutting fluid is as follows (1) Good lubrication performance, suitable for cooling and lubrication of ferrous metal cutting process. (2) Good emulsion stability, suitable for cutting, punching, and drilling of aluminum. (3) Good anti-rust performance, which can meet the anti-rust requirements between processes. (4) Good cleaning performance, can effectively clean equipment, simple operation. (5) Good cooling performance can effectively improve processing accuracy and prolong the service life of drilling tools and reduce production costs.
3. Application areas 3.1 Microemulsion cutting fluid is suitable for tools, molds, metal pipes, machine tools and other parts. 3.2 Water-based cutting fluid is suitable for non-ferrous metal, aluminum processing and other parts. On the whole, although both microemulsion cutting fluid and water-based cutting fluid are cutting fluids, they have the same advantages, but the difference between the two is still very big. At that time, you need to see which parts are used. Different parts require different cutting fluids, so that the cutting fluid can play the best role.
