In precision machining of parts, cutting tools greatly limit product quality and productivity. Although the cutting principle of CNC turning is basically the same as that of ordinary lathes, due to the requirements of CNC machining characteristics, special treatment must be given to the shape of the cutting edge when selecting cutting tools, especially when cutting the geometric parameters of the parts. To meet the machining requirements of CNC turning and fully leverage the advantages of CNC lathes.


When processing, it is necessary to pay attention to the requirements of CNC lathes for cutting tools. So, what are the requirements of CNC lathes for cutting tools?
1. High intensity. In order to adapt to the large cutting depth and fast feed of the tool when rough machining or machining parts with high hardness materials, the tool must have high strength. For long handled tools (such as deep hole turning tools), it should also have better anti vibration performance.
2. High precision. In order to meet the requirements of high precision and automatic tool changing in CNC machining, both the tool and its holder must have high precision.
3. The cutting and feed speeds are very high. In order to improve production efficiency and meet the needs of certain special processing, cutting tools should be able to meet the requirements of high cutting speed. For example, when polycrystalline diamond composite turning tools are used to process glass or carbon fiber composite materials, the cutting speed can reach 100M/min or higher.
4. High reliability. In order to ensure that the smooth processing of precision parts is not affected by damage and potential defects other than the cutting tool, the cutting tool and its combination accessories must have good reliability and strong adaptability.
5. High service life. The continuous wear of cutting tools during the cutting process will lead to changes in the machining dimensions. As the tool wears out, the cutting edge (or tip) will become dull, which will increase cutting resistance and greatly improve the surface accuracy of the machined part. The decline will exacerbate tool wear and form a vicious cycle.
6. Good cutting and chip removal performance. The effective performance of chip breaking and removal is of great significance for ensuring the smooth and safe operation of CNC lathes.

Therefore, the cutting tools used in precision parts machining, whether it is rough machining, precision machining, or special machining, should have a higher service life than ordinary lathes, in order to greatly reduce the number of tool replacements or grinding, as well as the number of tool adjustments. Ensure the machining quality of parts, improve production efficiency, and use tools with a long service life to complete at least 1-2 shifts of machining.
