As a key tool in turn-milling composite machining, the selection of tools is directly related to the machining quality and efficiency. When selecting tools, it is necessary to comprehensively consider factors such as the material of the parts, the processing requirements, and the performance of the machine tool to ensure that the tools can meet the processing requirements and perform at their best.
Material of parts: The material of the parts is the primary consideration for selecting tools. Parts of different materials have different requirements for the cutting performance of tools. For example, for materials such as high-strength and high-hardness alloy steel or stainless steel, tools with strong wear resistance and impact resistance need to be selected; while for soft materials that are easy to process, tools with higher cutting efficiency can be selected.
Processing requirements: Processing requirements include the dimensional accuracy, surface roughness, shape and position tolerance of parts. In order to meet these requirements, tools with corresponding cutting performance need to be selected. For example, for parts that require high-precision processing, tools with sharp cutting edges and low cutting forces should be selected; for parts that require low surface roughness, tools with good polishing effects can be selected.
Performance of machine tools: The performance of machine tools is also an important factor to consider when selecting tools. Machine tools with different performances have different adaptability to tools. For example, high-precision machine tools need to use matching precision tools to ensure machining accuracy; while high-power machine tools need to use tools that can withstand large cutting forces to ensure machining efficiency.

The cutting performance of the tool is one of the key factors that determine the machining quality. It includes the wear resistance, impact resistance and cutting efficiency of the tool. These performance indicators directly reflect the stability and reliability of the tool during the machining process.
Wear resistance: Wear resistance is an important indicator for measuring the service life of the tool. During the machining process, friction and wear will occur between the tool and the part, causing the cutting edge of the tool to gradually become blunt, the cutting force to increase, and the cutting efficiency to decrease. Therefore, tools with strong wear resistance can maintain a sharp state for a long time, improving the machining quality and efficiency.
Impact resistance: Impact resistance refers to the performance of the tool that is not easily damaged or deformed when subjected to cutting force. During the machining process, the tool will be subjected to impact force from parts and machine tools. If the impact resistance of the tool is insufficient, it will cause tool damage or cutting edge collapse, thereby affecting the machining quality and efficiency. Therefore, choosing a tool with strong impact resistance is crucial to ensure the stability and reliability of the machining process.
Cutting efficiency: Cutting efficiency refers to the ability of a tool to remove material per unit time. It reflects the cutting performance and machining efficiency of the tool. Tools with high cutting efficiency can complete more machining tasks in a shorter time and improve production efficiency. At the same time, tools with high cutting efficiency can also reduce energy consumption and cutting heat in the cutting process, and reduce thermal deformation and surface roughness of parts.
In turning and milling composite machining, the application of tools involves many aspects, including the installation and debugging of tools, the setting and optimization of cutting parameters, and the maintenance and maintenance of tools. These links are directly related to machining quality and efficiency.
Installation and debugging of tools: When installing tools, it is necessary to ensure the coaxiality between the tool and the machine tool spindle to avoid cutting errors caused by improper installation. At the same time, the tool needs to be debugged to ensure that the gap between its cutting edge and the part is appropriate to avoid interference and collision during the cutting process.
Setting and optimization of cutting parameters: Cutting parameters include cutting speed, feed rate, cutting depth, etc. The setting of these parameters needs to be comprehensively considered based on factors such as the material, shape, size and machining requirements of the parts. By optimizing cutting parameters, the cutting efficiency and processing quality of the tool can be improved. For example, for easy-to-process soft materials, the cutting speed and feed rate can be appropriately increased; while for hard materials that are difficult to process, the cutting speed and feed rate need to be reduced to ensure the wear resistance and impact resistance of the tool.
Tool maintenance and care: Tool maintenance and care are the key to ensuring its long-term stable operation and extending its service life. During use, the tool needs to be checked and cleaned regularly to remove the accumulated chips and oil on the cutting edge in time. At the same time, the tool needs to be lubricated and cooled to reduce friction and heat accumulation during the cutting process. For tools that are severely worn, they need to be replaced or repaired in time to avoid processing errors and reduced efficiency caused by tool damage.

The selection and cutting performance of the tool have an important influence on the processing quality of the adapter. On the one hand, suitable tools and cutting parameters can improve processing accuracy and surface quality, reduce processing errors and surface defects; on the other hand, the wear resistance and impact resistance of the tool can extend the service life, reduce the number of replacements and downtime, thereby improving processing efficiency and reducing costs.

In the adapter turning and milling compound precision machining, the selection of tools and cutting performance are the key factors to ensure machining quality and efficiency. By comprehensively considering factors such as the material of the parts, machining requirements and the performance of the machine tool, selecting tools with corresponding cutting performance, optimizing cutting parameters and performing regular maintenance and care, the machining quality and efficiency can be significantly improved, providing strong support for the development of modern manufacturing.
