When using a double-edged mill, in order to ensure machining quality and tool life, the following are some things to pay attention to:

1. Selection of cutting parameters: It is crucial to choose the right cutting speed, feed rate and cutting depth. These parameters need to be adjusted according to factors such as machining material, tool type and workpiece requirements to obtain the best cutting results and extend tool life.
2. Correct installation of the tool: Ensure that the double-edge milling cutter is correctly installed on the machine tool and fastened and stable. Avoid tool loosening or vibration, which can affect machining accuracy and tool life.
3. Fixing of the workpiece: Before processing, ensure that the workpiece is firmly fixed on the machine tool to prevent the workpiece from moving or flying out. This can avoid accidents and ensure machining accuracy.
4. The use of cutting fluid: The rational use of cutting fluid can help reduce the cutting temperature, reduce tool wear, and improve cutting efficiency. Select the appropriate cutting fluid according to the processing requirements and ensure that it is in sufficient supply.
5. Maintenance and maintenance of the tool: regularly check the wear of the double-edge milling cutter, and find that the worn or damaged blade should be replaced or repaired in time. Keep the tool clean to avoid debris and debris attached to the blade, affecting the cutting effect.
6. Safe operation: During the operation, comply with the safe operation procedures to ensure the safety of yourself and others. Avoid using a double-edged mill unattended or improperly operated to avoid accidents.

Following the above considerations can help you achieve better machining results and extend tool life when using a double-edge mill. At the same time, it also helps to improve production efficiency and reduce processing costs.
