Firstly, the role of coolant in CNC milling machines

The role of coolant in CNC milling machines is very important. Cooling fluid can reduce the heat generated during the machining process, thereby lowering the temperature of the cutting area and avoiding thermal cracking and deformation caused by excessive temperature. At the same time, the flushing effect of liquid on the workpiece and tool can remove debris in the cutting area and prevent tool wear, thereby extending the service life of the tool. In addition, coolant also has a lubricating effect, effectively reducing friction between cutting tools and workpieces, improving machining accuracy and surface quality.

Secondly, the type and selection of coolant

Common coolant is generally divided into hydraulic oil, cutting oil, cutting fluid, and rust remover. Choosing a suitable coolant requires consideration of factors such as the material of the workpiece, processing method, and processing temperature. For example, for metal materials with higher hardness, high-pressure evaporative cutting fluid should be chosen, while for soft materials that are easy to cut, water-soluble cutting fluid can be chosen.

Thirdly, precautions when using coolant

Although coolant has many benefits during the processing, the following issues also need to be noted during use. Firstly, the amount of coolant used should be moderate, as excessive use can waste resources. Secondly, the coolant should be replaced promptly after use and the waste coolant should be properly disposed of. Finally, attention should be paid to the impact on the working environment during the use of coolant, and efforts should be made to minimize splashing and contamination of the coolant.

In summary, coolant plays a very important role in CNC milling machines. The correct selection and use of coolant can improve machining efficiency and quality, prolong tool life, and have minimal impact on the environment.
