霸刀分享-金属切削加工中的毛刺问题及解决方法
金属切削加工中的毛刺问题可以通过优化加工工艺、改进刀具设计以及采用合适的去毛刺方法来有效解决。
金属切削加工中，毛刺是常见的缺陷之一，直接影响零件的精度、表面质量以及使用安全性。毛刺不仅影响外观，还可能导致零件在装配或使用过程中出现故障，因此必须加以控制或去除
毛刺常见于钻孔、铣削、车削、齿轮加工等过程中，主要受以下因素影响：
工件材料的塑性：塑性越高，越容易形成毛刺；
切削参数：如进给速度、切削深度等；
刀具状态：磨损刀具容易导致毛刺增大；
加工方式：不同加工方式对毛刺形成影响显著。
毛刺的解决方法
1. 工艺优化
①调整加工顺序和走刀方向；②控制切削参数（如减小进给量和切深）；③使用合适的切削液以减少黏结；④对工件进行适当热处理以降低塑性 。
2. 刀具改进
①选择高硬度、高耐磨性的刀具材料；②提高刀具前刀面光洁度③增大刀具前角；④根据材料特性调整切削速度 。
Burr problems and solutions in Metal Cutting processes
The burr problem in metal cutting can be effectively solved by optimizing the processing technology, improving tool design and adopting appropriate deburring methods.
Burrs are one of the common defects in metal cutting processes, directly affecting the accuracy, surface quality and safety of parts in use. Burrs not only affect the appearance but may also cause malfunctions of parts during assembly or use, so they must be controlled or removed
Burrs are commonly found in processes such as drilling, milling, turning, and gear processing, and are mainly influenced by the following factors:
The plasticity of the workpiece material: The higher the plasticity, the easier it is to form burrs.
Cutting parameters: such as feed rate, cutting depth, etc.
Tool condition: Worn tools can easily lead to increased burrs.
Processing methods: Different processing methods have a significant impact on the formation of burrs.
Solutions to burrs
1. Process optimization
① Adjust the processing sequence and tool path direction; ② Control cutting parameters (such as reducing feed rate and depth of cut); ③ Use appropriate cutting fluid to reduce adhesion; ④ Conduct appropriate heat treatment on the workpiece to reduce its plasticity.
2. Tool improvement
① Select tool materials with high hardness and high wear resistance; ② Improve the surface finish of the rake face of the tool ③ Increase the rake Angle of the tool; ④ Adjust the cutting speed according to the material properties.
