Latest company news about What are the classifications of cutting fluids?

Cutting fluid is an industrial fluid used to cool and lubricate tools and machined parts during metal cutting and grinding. Reasonable use of cutting fluid in cutting can not only reduce the friction between the tool and the chips, the tool and the machined surface, but also It can reduce the cutting force and cutting temperature, reduce tool wear, and improve the quality of the machined surface. But what do you know about the classification of cutting fluid? What is the choice of cutting fluid?

What are the classifications of cutting fluids?

There are two classification standards for cutting fluids, one is based on the composition and corresponding performance of the cutting fluid, and the other is directly divided into "oil-based cutting fluid" and "water-based cutting fluid". Here we just come to understand the common classification according to the composition of cutting fluid.

1. Aqueous solution

The main components of the aqueous solution are: water, anti-rust additives, and lubricating additives. This aqueous solution has a better cooling effect and is commonly used in ordinary grinding and some finishing.

2. Emulsion

Emulsions can be divided into different additives according to different additives: ordinary emulsions (in addition to good cleaning and cooling performance, but also anti-rust and lubricating properties), anti-rust emulsions (more anti-rust performance), extreme pressure emulsions ( The adsorption film is formed under high temperature and high pressure, which plays a very good lubricating effect).

3. Cutting oil

Cutting oil is divided into 3 types according to the oil type: mineral oil (general lubrication), dynamic/plant oil and compound oil (boundary lubrication), extreme pressure cutting oil (with good lubrication performance and extreme pressure lubrication performance).

 

What is the choice of cutting fluid?

The content of the selection principle of cutting fluid is really quite a lot.

When roughing, we should pay attention to the choice of cutting fluid, because the roughing cutting amount and cutting allowance are large, it will generate a lot of cutting heat, and it is easy to cause rapid tool wear. In this case, we generally choose good cooling. , And has certain cleaning, lubricating and anti-rust performance cutting fluid.

When cutting difficult-to-machine materials such as high-strength steel and high-temperature alloys, cutting fluids containing extreme pressure additives should be used because the cutting process is in a state of extreme pressure lubrication friction.
