Metal cutting, as an indispensable processing procedure in machining centers, is widely used in daily machining operations. Our company focuses on metal-cutting technology for 20 years and has deep processing experience in the field of metal cutting. Today I will tell you about the knowledge of cutting fluids in metal cutting in machining centers. It is convenient for everyone to better complete this important processing process, so as to produce more efficiently and safely.

What is the function of cutting fluid?

Cutting fluid is an industrial fluid specially designed for CNC machining centers to cool and lubricate tools and workpieces in metal cutting, grinding and grinding operations. Cooling and lubrication are its two main functions. In addition, it also has the advantages of anti-rust, degreasing cleaning, anti-corrosion, easy dilution, etc., and it is non-toxic, odorless, non-corrosive to the human body, non-corrosive to equipment, and non-polluting to the environment, which is a must for machining center cutting operations. few auxiliary materials.

Types of cutting fluids

Cutting fluid can be divided into water-soluble and oil-soluble according to the purpose, which is what we often call cutting fluid and cutting oil. When choosing to use cutting fluid or cutting oil, pay attention to two points. One point is concentration. Under normal circumstances, the concentration of cutting fluid is 5%. When focusing on the use of anti-rust functions, such as rough machining, rough grinding, and cast iron machining, the concentration can be configured to 3%. The concentration can be increased to 10% when the machining center is carrying out heavy duty machining.

In general, the cooling effect of cutting fluid is greater than that of lubrication, and it has good results in low-speed machining. And because the cutting fluid is mostly water, it is easy to clean the product. However, it is easy to damage the tool when processing products with high work hardening and poor heat dissipation. For example, when machining stainless steel, the effect of cutting oil is definitely better than that of cutting fluid. It should be noted that in the cutting process, if the workpiece has requirements on the surface finish, it is recommended to use cutting oil. Cutting oil has a more lubricating effect than a cooling effect, and can ensure the continuity of chips and smooth chip removal. The disadvantage is that it is not environmentally friendly, and it is not easy to clean when machining parts in batches.

Cutting fluid and cutting oil are mostly light green, light blue and light yellow with good visibility, especially suitable for use on modern processing equipment such as CNC machining centers. Cutting fluid processing is cheap but plays an irreplaceable role in the daily production of machining centers, and is an important guarantee for metal cutting operations.
