End mills have a service life of about 3,000 to 4,000 hours, which can be significantly extended through high-quality material selection, proper conditions of use, and timely maintenance, while avoiding overload and improper storage. The specific methods are as follows:
Material selection
The material of the end mill directly determines its durability and resistance to wear. High quality carbide or high speed steel materials, with their excellent hardness, toughness and heat resistance, are the first choice for extending the life of end mills. These materials maintain a sharp cutting edge during high-speed cutting, reducing wear and thereby increasing the overall life of the tool.
Conditions of use
Control cutting parameters: reasonable selection of cutting speed, feed rate and cutting depth, avoiding overload use, is the key to protect the end mill and extend its life. High cutting parameters can lead to rapid tool wear and even damage.
Choose the right coolant: The coolant can not only reduce the cutting temperature, reduce the damage of thermal stress to the tool, but also play a lubricating role, reduce friction and wear. Therefore, it is important to choose the right coolant according to the processing material and tool material.
Maintain the stability of the workpiece and the tool: the workpiece and the tool should be fixed firmly and reliably to avoid vibration during the cutting process. Vibration will not only reduce machining accuracy, but also increase tool wear.
Timely maintenance
Regularly check the status of the tool: regularly check whether the cutting edge of the end mill is sharp, whether there is a crack or crack, and timely replace the damaged tool to prevent the problem from expanding.
Regular cleaning and lubrication: the chips and impurities generated during the cutting process will be attached to the tool, affecting the cutting effect and tool life. Therefore, regularly clean the surface of the tool, and apply the right amount of lubricating oil in the key parts to keep the tool in good condition.
Correct storage
When the end mill is not in use, it should be stored in a dry, ventilated and dust-free environment to avoid moisture, corrosion and collision. At the same time, it should be stored in classification to avoid confusion and misuse.
In summary, through the selection of high-quality materials, rational use of tools and regular maintenance and maintenance measures, can effectively extend the life of end milling cutter, improve processing efficiency, reduce production costs. This is of great significance to enhance the competitiveness and profitability of enterprises.
