The importance of material selection | pressed or drawn material?
In the world of metalworking, choosing the right material is crucial, especially when it comes to high-precision processes like turning. At Strobel Industry, we have extensive experience with different materials and understand how significant the differences between drawn and pressed material can be. In this blog post, we discuss why these differences are especially important in turning and how they can affect the precision of your parts.
Basic difference between drawn and pressed material:
Drawn material: It is produced through a process called "cold drawing" in which the metal is pulled through a die. This results in high dimensional accuracy and a uniform microstructure.
Pressed material: This is where the metal is pressed into a mold under high pressure. This process can result in less uniform microstructures and in some cases cause microcracks or inhomogeneities in the material.
Influence on machining precision when turning:
Drawn material: Due to its uniform structure and strength, it allows for greater precision in turning. This results in less distortion and ensures that parts can be manufactured within tight tolerances.
Pressed material: As you have noticed, this can cause problems with precision. The inhomogeneous structure can lead to uneven material removal during turning, resulting in parts that tend to be more oval and less dimensionally stable.
Practical examples from industry:
At Strobel Industry, we have found that customers who require high-precision components often prefer drawn material. For example, in the aerospace industry, where every micrometer deviation can be critical.
In less critical applications where cost is a greater consideration, pressed material can be a cost-effective alternative.
Tips for material selection and processing:
Material quality: Always pay attention to the quality of the raw material. At Strobel Industry we only use materials from trusted suppliers.
Machining parameters: Adjust the cutting speed, feed and cooling to achieve the best results with the selected material.
Conclusion:
The choice between drawn and pressed material should not be made lightly, especially when precision turning is involved. At Strobel Industry, we understand the nuances that come with each material type and are committed to helping our customers make the right choice for their specific needs.
