In order to make the milling cutter more durable, the correct use and maintenance method is very important. Here are some key steps and suggestions:

First, the correct use of milling cutter

1. Choose the right milling cutter: According to the different processing materials, choose the right type of milling cutter. For hard materials, for example, it may be necessary to use a milling cutter with high hardness and wear resistance.
2. Reasonable setting of parameters: According to the processing needs, reasonable setting of milling cutter speed, feed speed and other parameters. Avoid excessive speed and feed speed to reduce cutter wear and heat accumulation.
3. Avoid excessive cutting: During the processing, avoid excessive cutting to reduce the load and wear of the milling cutter.
4. Pay attention to the use of coolant: The use of coolant can effectively reduce the cutting temperature and reduce the thermal deformation and wear of the milling cutter.

Two, maintain the milling cutter

1. Regular cleaning: After using the milling cutter, the cuttings, oil and other impurities on the milling cutter should be cleaned in time to keep the milling cutter clean and sharp.
2. Regular grinding: After the milling cutter is used for a period of time, the cutting edge will gradually wear out and need to be sharpened. The sharpening can restore the sharpness of the milling cutter and improve the machining efficiency and accuracy.
   3.Inspection and maintenance: check the wear of the milling cutter regularly, and if necessary, repair or replace it in time. At the same time, pay attention to check whether the tightening screws of the milling cutter are loose, and if they are loose, they should be tightened in time.
3. Storage environment: When storing the milling cutter, it should be placed in a dry and dust-free environment to avoid the surface of the milling cutter from being contaminated by moisture, oxidation or other substances.

In addition, the following points need to be noted:

1. In the process of handling, installation and disassembly, attention should be paid to protecting the cutting edge accuracy of the milling cutter to avoid collision and damage.
2. For milling cutters that are not used for a long time, anti-rust oil can be applied to protect them to prevent rust.

In summary, through the correct use and maintenance of the milling cutter, its service life can be extended and the processing quality and efficiency can be improved. At the same time, in order to ensure the safety and correctness of the operation, it is recommended that the maintenance and maintenance work of the milling cutter be carried out by professionals.
