Stainless steel 304 is a popular choice in manufacturing due to its strength, durability, and ability to resist corrosion. Cutting it with a CNC machine offers improved accuracy and speed compared to traditional methods. One thing to keep in mind is the surface footage, which refers to the speed of the cutting tool over the material's surface.

Typically, a surface footage of 200 ft/min is a good speed for cutting stainless steel 304. This fast pace can result in quicker cutting, but it also puts more wear on the cutting tool and generates more heat. To avoid any issues, using high-quality cutting tools and proper cooling techniques, such as a coolant or lubricant, is crucial.

However, it's important to remember that the surface footage can affect the quality and precision of cuts, as well as the project's overall cost. Too fast can cause rough cuts and decreased tool life, while too slow leads to longer cutting times and higher costs.

In short, cutting stainless steel 304 with a CNC at 200 ft/min offers speed and efficiency, but it's crucial to consider the impact on quality and cost. By using the right tools and cooling techniques, you can achieve the best results when cutting this material.
