Thin wall machining is prone to deformation and damage due to its thin wall thickness and low strength, so special attention should be paid to tool selection.

 The following is a detailed analysis of the selection of thin-walled machining tools:

1、 Tool type

Milling cutter: mainly used for cutting flat surfaces, grooves, and contours. There are various types of milling cutters, including end mills, face mills, etc. When

 choosing, factors such as material, hardness, and wear resistance need to be considered to ensure stability and durability during the processing.

Drill bit: mainly used for drilling holes on thin-walled components. Due to the thin wall thickness of thin-walled components, it is required that the drill bit has 

high precision and stability to avoid deformation or damage to the components during the drilling process. Fried Dough Twists drill, center drill, etc. are common

 drill types, and factors such as the diameter, depth and material of the drill should be considered when selecting.

Boring tool: mainly used to enlarge existing holes or machine precise holes. In thin-walled machining, boring cutters can be used to correct the size and shape of

 holes to achieve the required accuracy and surface quality. When choosing, factors such as rigidity, accuracy, and durability should be considered.

Reamer: mainly used for precision machining of holes, which can further improve the machining accuracy and surface quality of the holes. Compared to boring 

cutters, reamers pay more attention to the refinement of holes and the improvement of smoothness.

When choosing, factors such as material, blade treatment, and dimensional accuracy need to be considered.

2、 Tool material

Hard alloy cutting tools: suitable for thin-walled machining of high-strength materials such as aluminum alloys. Hard alloy has high hardness and wear resistance, 

which can maintain the sharpness and service life of cutting tools.

PCD (Polycrystalline Diamond) cutting tools: made of polycrystalline diamond, with high hardness, strong wear resistance, and excellent thermal conductivity, suitable

 for high-speed and efficient machining.

CBN (cubic boron nitride) cutting tools: made of cubic boron nitride, they have high hardness, high thermal stability, and wear resistance, especially outstanding in 

steel processing.

3、 Tool Structure and Design

Tool rake angle: The rake angle should not be too small, otherwise it may increase cutting deformation and friction, resulting in increased wear on the front cutting 

surface and reduced tool life.

Blade tip radius: It should be selected appropriately, and the teeth should not be too dense to facilitate chip discharge, prevent cold hardening layer, and extend the

 service life of the tool.

In summary, the selection of cutting tools for thin-walled machining should be determined based on specific machining requirements and component materials. 

Choosing the appropriate tool type, material, and structure can ensure the stability and efficiency of the machining process, while improving the machining quality 

and accuracy of thin-walled parts.
