Choosing machining tools for CNC lathes is a process that requires comprehensive consideration of multiple factors. Here are some key steps and considerations:

1. Clarify the processing requirements: First, the specific processing requirements need to be clarified, including the type, size, hardness and other characteristics of the material to be processed, as well as the required processing accuracy and surface roughness. This information is crucial for selecting appropriate tool materials and geometric parameters.

2. Select appropriate tool materials: The selection of CNC lathe tool materials should take into account the characteristics of the material being processed as well as the cutting force, heat and wear during the processing. For example, for harder materials, it may be necessary to select a tool material with higher hardness and wear resistance.

3. Determine the tool geometric parameters: The geometric parameters of CNC lathe tools, such as main declination angle, secondary declination angle, rake angle and edge inclination angle, will directly affect cutting force, cutting heat and tool durability. Therefore, appropriate geometric parameters should be selected based on the processing requirements and the characteristics of the material being processed.

4. Consider tool type and size: CNC lathe selects the appropriate tool type (such as turning tool, milling cutter, drill bit, etc.) and size according to the processing needs. Ensure that the tool is compatible with the clamping system and control system of the CNC lathe and can meet the requirements for machining accuracy and efficiency.

5. Consider the durability and economy of the tool: When selecting a tool for a CNC lathe, you also need to consider its durability and economy. Tools with good durability can reduce the number of replacements and downtime, and improve production efficiency. At the same time, the price and procurement cost of the tool must also be taken into consideration to ensure that economic benefits are maximized while meeting processing needs.

6. Refer to the manufacturer’s recommendations and practical application experience: When selecting CNC lathe processing tools, you can refer to the tool manufacturer’s recommendations and suggestions, and make adjustments and optimizations based on practical application experience and processing effects.

To sum up, choosing a CNC lathe processing tool requires comprehensive consideration of multiple factors, including processing requirements, material properties, geometric parameters, tool type and size, durability and economy, etc. By scientifically and rationally selecting cutting tools, processing efficiency and quality can be improved, and production costs can be reduced.
