In modern mechanical manufacturing, milling processing is a common metal cutting process, widely used in the production of various components and parts. However, in the actual processing process, the problem of tool wear seriously affects processing efficiency, quality, and production costs. Therefore, studying how to effectively reduce tool wear in milling processing is of great significance for improving production efficiency and product quality.



Firstly, reasonable selection of tool material is the key to reducing tool wear. Currently, commonly used milling tool materials include high-speed steel (HSS), hard alloy, ceramic, and cubic boron nitride (CBN). Different processing materials and conditions should choose the corresponding tool materials. For example, when processing high-hardness materials, it is recommended to use hard alloy or ceramic tools, which have good wear resistance and high-temperature hardness; while in rough processing, high-speed steel tools still have certain application space due to their good toughness.



Secondly, optimizing cutting parameters is also an important means to reduce tool wear. Cutting speed, feed rate, and cutting depth directly affect the working state of the tool. Excessive cutting speed can cause the tool temperature to rise, accelerating tool wear; while excessive feed rate will increase cutting force, leading to edge chipping. Therefore, it is necessary to reasonably adjust cutting parameters while ensuring processing efficiency, avoiding the tool from working under extreme conditions.

　　Thirdly, using a suitable cooling and lubrication system can significantly reduce tool wear. By means of cutting fluid or micro-lubrication (MQL), the temperature of the cutting area can be effectively reduced, friction can be reduced, and the service life of the tool can be improved. Especially when processing difficult-to-cut materials such as stainless steel and high-temperature alloys, good cooling and lubrication is particularly important.



Fourthly, improving the geometric structure of the tool can also effectively reduce wear. For example, increasing the anterior angle can reduce cutting resistance and cutting temperature, thereby delaying tool wear; choosing appropriate edge treatment methods (such as chamfering, passivation) can also enhance tool strength and improve its wear resistance.



In addition, regular inspection of tool condition and timely replacement of worn-out tools can not only ensure the quality of processing but also avoid sudden tool breakage due to excessive wear, affecting equipment safety and production progress.



In summary, reducing tool wear in milling processing requires efforts from multiple aspects such as tool material selection, optimization of cutting parameters, application of cooling and lubrication systems, tool structure design, and daily maintenance. Through scientific and reasonable measures, not only can the service life of the tool be extended, but also the processing efficiency and quality can be improved, creating greater economic benefits for the enterprise.
