CNC Surface finish affects whether your CNC part works or fails. It changes friction, sealing, wear, and corrosion resistance. This guide covers how finish is measured, what the common finish types are, how cost is affected, and how to write finish correctly on your drawings.
CNC machining tolerances are used to ensure parts fit and work together. In this article, we’ll look at normal and tight tolerances, tolerance selection, and how to control your production expenses. You’ll discover how to design economical, high-quality parts.

Metals and plastics are two main CNC machining materials. In metals, Aluminum 6061, 7075, Stainless Steel 303, 304, 316, carbon steel, brass and titanium are prominent. In CNC plastics, Acetal, ABS, PEEK, and Nylon are the main types.
On average, 3-axis CNC machining costs $75–$200 per hour. 5-axis machines cost $200–$350+ per hour. Simple machined parts can cost as little as $10–$50, and complex parts start from $100. Most people focus only on the hourly rate, but the real price depends on your design and the order size.
Why is aluminum hard to machine? Aluminum is a fast metal to cut, but fast does not always mean easy. In a real workshop, you will face a few common problems. First, the waste metal can turn into long strings that wrap around your tools. Second, the metal parts might bend or change shape after you finish the work.
