Correct use of cutting fluid can make the tool even more powerful in processing
- Jul 28, 2018 -

First understand the role of cutting fluid:

 

1, lubrication

 

2, cooling effect

 

3, cleaning effect

 

4, anti-rust effect

 

Then, according to the specific processing environment, it is considered from the perspective of the cutting process requirements.

 

The cutting fluid selection principle is as follows:

1, according to the choice of workpiece materials

 

Cast iron and bronze are generally not used for cutting. When finishing, use kerosene.

 

Kerosene when cutting aluminum

 

When cutting non-ferrous metals, it is not advisable to use a sulfur-containing cutting fluid.

 

Mineral oil is used when cutting magnesium alloys.

 

When cutting general steel, use an emulsion.

 

Extreme pressure cutting fluids should be used when cutting difficult materials.

2, according to process requirements and cutting characteristics

 

When roughing, choose a cutting fluid with good cooling effect.

 

When finishing, you should choose a cutting fluid with good lubrication effect.

 

When processing holes, use a large concentration of emulsion or extreme pressure cutting fluid.

 

For deep hole processing, a cutting fluid containing a lower concentration of extreme pressure additives should be used.

 

When grinding, the cutting fluid should be cleaned.

 

When cutting with carbide, ceramic and PCD, PCBN tools, cutting fluid is generally not used. When it is to be used, it must be supplied from beginning to end. When cutting PCBN tools, water quality cutting fluid cannot be used. When the CBN is at a high temperature of 1000 ° C or higher, it will be chemically reacted with water and consumed.

 

The use of cutting fluid is also a door in the processing of the blade. The important point is that it can not damage the machine tool, so it is very important to choose according to the processing material.
