1. Poor rigidity, prone to chattering and tool vibration during machining, affecting machining accuracy and surface quality.
2. After being subjected to force, it is easy to deform. Therefore, how to effectively control internal stress deformation, clamping deformation, cutting force deformation, and cutting thermal deformation during the machining process is the key to ensuring the accuracy of parts.
3. The tool has a long overhang and is prone to vibration during machining.
4. The material has good toughness, but the band shaped chips produced have poor chip breaking performance, making it difficult to remove chips when tangled together.
