CNC machining has transformed the manufacturing industry with its exceptional precision and accuracy. However, the machining process can differ significantly depending on the material being used. In this article, we’ll compare CNC machining of aluminum parts with that of stainless steel, highlighting key process differences and important considerations.
| Type | Tolerance |
|---|---|
| Linear Dimension | +/- 0.025 mm +/- 0.001 inch |
| Hole Diameters (not reamed) | +/- 0.025 mm +/- 0.001 inch |
| Shaft Diameters | +/- 0.025 mm +/- 0.001 inch |
| Part Size Limit | 950 * 550 * 480 mm 37.0 * 21.5 * 18.5 inch |
Process Differences
The primary differences between CNC machining aluminum and stainless steel parts include:
| Size | Metric units | Imperial units |
|---|---|---|
| Max. part size for soft metals & plastics | 2000 x 1500 x 200 mm 1500 x 800 x 500 mm | 78.7 x 59.0 x 7.8 inch 59.0 x 31.4 x 27.5 inch |
| Max. part for hard metals | 1200 x 800 x 500 mm | 47.2 x 31.4 x 19.6 inch |
| Min. feature size | Ø 0.50 mm | Ø 0.019 in |
Conclusion
While CNC machining aluminum and stainless steel parts share similarities, understanding the differences is key to achieving optimal results. Aluminum requires careful management of heat and burr formation, while stainless steel demands robust tools and strategies to manage wear and heat. By paying attention to these factors, manufacturers can produce high-quality parts from either material. If you have any questions about machining these materials, feel free to consult us.
