When machining stainless steel sheet compared to aluminum alloy sheets, what is the recommended speed?

When machining stainless steel sheets, the recommended approach is to use lower speeds combined with more pressure compared to machining aluminum alloy sheets. This is due to the inherent properties of stainless steel, which is generally harder and tougher than aluminum.

Machining stainless steel at lower speeds allows for better control over the cutting process and reduces the risk of tool wear. Higher speeds can generate excessive heat, which may cause the metal to work harden or even lead to tool failure. Additionally, applying more pressure helps to ensure that the cutting tool effectively engages with the material, allowing for cleaner cuts and a better finish.

In contrast, aluminum alloy is softer and conducts heat more effectively, allowing it to be machined at higher speeds without significant risk of damaging the material or the cutting tool. Therefore, a different approach in terms of speed and pressure is necessary when machining the two materials to achieve optimal results.
