The main difference between 3-axis and 5-axis milling machines is that the workpiece can be worked on from three axes with the former and five axes with the latter. Both are highly versatile, automated, and replicable production processes that will enable you to quickly and cost-effectively create accurate components. However, you may opt to use one over the other for a variety of reasons.

If you’re on a budget or only need to cut a flat surface, 3-axis machines might be the way to go. In addition to being more affordable than those with five axes, 3-axis machines are simpler to program, so you won’t have to incur the cost of working with expensive expert programmers and operators. Plus, prep time is shorter with 3-axis machining.

If you need to produce a deeper part or one with complex geometry, you’ll probably want to use 5-axis machining. Using 5-axis machines lets you machine the workpiece from all sides — no manual rotation required. With 5-axis machining, you’ll have higher yields, greater accuracy, and increased freedom of movement, as well as the ability to manufacture larger parts faster.
