You're having difficulties with a precision component for a critical medical device. The part won't fit the assembly. Or the finish isn't right. Or the quality/consistency is hit and miss. Or any number of other issues. But your existing supplier – who perhaps has been reliable up until now – is pushing back: they did "exactly as instructed", they protest. They followed your drawings/CAD models "to the letter". So what went wrong? And how can it be fixed quickly and cost-effectively? You want a second opinion – is the issue with the supplier, the drawings or both?
Choosing the right metal for CNC machining isn't just a design decision; it has a direct impact on performance, reliability, and cost. When a part fails or wears out too quickly, the root cause is often the material. That's why material testing is such a critical step in the process. We'll explore what to consider when selecting metals for CNC machining, and how testing helps verify that choice.
Threaded holes are a small but essential detail in CNC part design. If they're not specified correctly, they can lead to fit issues, tool breakage, or even part failure during assembly. You'll learn how each threading method works, when to use them, and how to avoid common pitfalls. We'll also touch on materials, tooling limitations, and how to clearly communicate your thread specs. Whether you're prototyping or placing a production order, this guide helps you get threads right the first time.
