How to select a tool

Due to the much higher spindle speed and range of CNC machine tools compared to ordinary machine tools, as well as the large output power of the spindle, higher requirements are put forward for CNC machining tools that include high precision, high strength, high rigidity, high durability, high durability, dimensional stability, and easy setting and adjustment compared to previous machining methods. This requires appropriate tool structure, standardization, and concatenation of geometric parameters. CNC tools are one of the prerequisites for improving machining efficiency, and their selection depends on the shape of the machining object components, the state of the material, the rigidity of the fixture, and the tool selected by the machine tool.
Please consider the following:
1. Select cutting tools based on the cutting performance of parts and materials.
For rotating or grinding high-strength steel, titanium alloy, and stainless steel components, it is recommended to use indexable carbide tools with better wear resistance.
2. Select the tool according to the part processing stage.
That is to say, in the rough machining stage, the stiffness is mainly reduced by removing precision machining, with the aim of selecting more accurate tools. In the semi precision machining process, the machining accuracy and product quality of the parts are mainly ensured, but the durability of higher performance and high-precision tools is ensured. The tool accuracy used in the rough machining stage is relatively low. In addition, the precision of the tools used in the precision machining table is very high.
If the same tool is selected for rough and finish machining, most of the tool edges removed from the finish machining will wear slightly and wear due to coating wear. Therefore, it is recommended to choose the tool removed from the finish machining during the rough machining process. Continuous use can affect precision machining. The processing quality has little impact on the rough surface treatment.
3. Select tools and geometric parameters according to the characteristics of the machining area.
If the structure of the part is acceptable, tools with large diameter and small aspect ratio must choose the edge of the supercenter milling tool to cut thin-walled and ultra-thin pendulum parts, and there must be sufficient centripetal angle to reduce the cutting force of the tool and cutting parts. In processing components made of soft materials such as aluminum or copper, choose an end mill with slightly larger angles that do not exceed 4 teeth.
