Why Choose Stainless Steel for Aerospace CNC Machining?

Stainless steel is a preferred material in aerospace manufacturing due to its:

  • High Strength & Durability – Resists extreme temperatures and mechanical stress.

  • Corrosion Resistance – Ideal for harsh environments, including high humidity and chemical exposure.

  • Precision Machinability – Allows for tight tolerances and complex geometries.

  • Longevity – Ensures extended service life with minimal maintenance.

Stainless steel offers numerous benefits, from attractive finishes to superior strength and durability. However, these characteristics can present challenges for machines and operators. Stainless steel is a tough opponent due to its superior strength and durability, which are the reasons for its widespread use. Many factors, in terms of alloy selection, processing speeds, and tools, will affect your final product and the process of making it.

Machining stainless steel parts requires some preparation and a deep understanding of the material. Here are some of our stainless steel machining tips.
 
When machining stainless steel, you have to take all of its properties into account. Remember, it is strong even at high temperatures.

1. End mill
 
The tools you use will have a significant impact on your project and can cause damage to your machine. The ideal type of end mill will depend on the application, but tools made from high-speed steel or carbide are recommended. High-speed steel often contains tungsten and molybdenum, which is suitable for a variety of machining needs. Carbide is a good choice when higher feeds or speeds are required. Make sure your tools are kept sharp and in good condition to ensure high-quality cuts.
 
Roughing
Roughing steel can be done effectively using an end mill with 4-5 flutes. Keep in mind that higher RPMs allow room for higher feed rates.
 
Grooving
When grooving steel, pay special attention to chip control to avoid tool seizure or damage to the finished product. Try using a 4-flute end mill, which will more effectively move chips away from the cutting area.
 
Finishing
For finishing steel parts, it is recommended to use a large number of flutes or a high helix tool above 40 degrees, which will give better results.

2.Feeds and Speeds

After selecting the right tool, it is also important to make sure your cutting speed is right. While some fine-tuning may be required, a good starting point is 100 to 300 surface feet per minute (SFM). Chip load will depend on the size of the tool, so make sure to adjust it accordingly to optimize the machining results.
 
Steel can be tricky to machine, but it’s not too bad if you are prepared and use the right settings and tools. Be sure to keep these concepts in mind as you machine steel.
 
Keep it cool

During steel machining, temperatures can get very high, so it is vital to take precautions to reduce their effects. Always use cutting fluid. Keeping heat away from the cutting area is critical to maintaining optimal tool performance when machining hardened and low thermal conductivity materials. If the heat in the cutting area is too high, it can cause deformation and reduced corrosion resistance. Cutting fluid not only provides lubrication, but also cleans chips, reduces tool wear, and effectively cools the end mill. Common cutting fluids include mineral oil and emulsified oil. Make sure to use enough coolant, as any interruption in the coolant will cause temperature fluctuations that will affect the life of the tool.
 
Avoid work hardening

Many steels have a high tendency to work harden, so ensuring that tools remain sharp is essential. Also, try to keep the tool moving continuously to avoid pauses during the cut, which reduces heat build-up and the risk of work hardening.

Controlling Vibration

The strength of stainless steel and the speed required of the cutting tool can cause significant vibration. Vibration of the work surface not only damages the finish but also increases tool wear. Therefore, it is necessary to select strong and hard tools that can be used for high-speed cutting. Make sure the workpiece is firmly fixed in place and use clamps to reduce any tool overhang. In addition, you can try using tools with a small nose radius to further reduce vibration and improve machining results. 
 
Know Your Materials

Each steel alloy has its own unique characteristics, so it is important to understand the properties of the material you are using. This will help you better adjust your machine to the requirements of your specific material. For example, the addition of sulfur can help the tool edge remain consistent by affecting the hardening of the chips, allowing for higher feed rates. Whereas the addition of lead can increase cutting speeds because it provides lubricating properties that help reduce heat. A deep understanding of the material's characteristics will help optimize the cutting process and improve machining efficiency.
