The main properties of water soluble metal cutting fluid
In order to achieve the above purpose, requirements of water soluble metal cutting fluid must have the following main performance:
In the metal cutting process, the consumption of energy, the vast majority (over 90%) into cutting heat, it not only makes the tool easy to wear, and to make the work easy to generate a local burn or dark, affect the machining precision and machining quality of workpiece surface. Therefore, the requirement for water soluble metal cutting fluid has good cooling performance.
Cutting tool in cutting workpiece moment, usually suffer great cutting force, good lubrication properties of water soluble metal cutting fluid can reduce the friction between the tool rake face and chip, tool and workpiece surface and wear, prolong the service life of the cutter and the workpiece obtain good precision and rough degree; more important is to reduce bue during cutting (i.e. knife tumor) chance.
In metal cutting (or grinding) process, oil, fine cutting and grinding wheel, metal powder sand and bond with each other, adhere to the workpiece, cutting tool and machine tool, influence the machining quality of workpiece, tool and reduce the service life of the wheel, affect the accuracy of machine tools. Therefore, the water soluble cutting fluid should be a good cleaning effect, reduce fine bonding chips and metal powder to facilitate cleaning, and quickly into small chips and the metal powder in time away.
Water soluble metal cutting fluid in the process of using mostly water (about 80%-98%), provide a favorable environment for corroded, and the water soluble metal cutting fluid in the extreme pressure agent and some surfactants tend to exacerbate corrosion; at the same time, the water soluble metal cutting fluid must have rust the performance of the workpiece does not produce corrosion short time during processing and after processing; at the same time, good performance of water soluble antirust metal cutting fluid, and can also ensure that the internal cutting fluid circulation system and the machine does not produce corrosion and corrosion phenomenon, to maintenance of equipment function.
