The structure of CNC lathe processing tools can be divided into the following main parts:

1. Tool body (tool handle): The CNC lathe tool body is the main part of the tool. It is usually made of steel or carbide and has good rigidity and wear resistance. The shape and structural design of the cutter body will affect cutting performance and machining accuracy.

2. Tool tip: The CNC lathe tip is the cutting part of the tool, usually made of carbide or high-speed steel. The shape and angle of the tool tip affect cutting efficiency, surface quality and tool life.

3. Blade (cutting edge): The CNC lathe blade is a key part of the tool and directly contacts the workpiece for cutting. The shape, material and edge treatment of the insert all affect the quality of the cut and the durability of the tool.

4. Blade fixing parts: CNC lathe blade fixing parts include clamps, clamping bolts, etc., which are used to fix the blade on the tool body. Its design and structure will affect the stability and cutting accuracy of the tool.

5. Tool interface: The CNC lathe tool interface is the part that connects the tool to the CNC lathe spindle. Common interfaces include straight shank interface, tool seat interface, etc. Its design and specifications need to match the CNC lathe.

6. Tool accessories: CNC lathe tool accessories include cutting fluid supply systems, tool measurement systems, etc., which are used to improve cutting efficiency and machining accuracy.

The combination and structural design of these components of CNC lathes will be adjusted and optimized according to different processing needs, workpiece materials and processing conditions to achieve the best cutting performance and processing efficiency.
