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.

5-axis machines rely on a tool that moves in five different directions — X, Y, and Z, as well as A and B, around which the tool rotates. Using a 5-axis CNC machine lets operators approach a part from all directions in a single operation, eliminating the need to manually reposition the workpiece between operations. 5-axis CNC machining saves time and is ideal for creating complex and precise parts like those found in the medical, oil and gas, and aerospace industries. There are a few different kinds of 5-axis machines that product teams should be aware of, including indexed 5-axis CNC machines, continuous 5-axis CNC machines, and mill-turning CNC centers.
Like 3-axis CNC milling, the cutting tool only moves along three axes and doesn’t maintain continuous contact with the workpiece in indexed 5-axis CNC machining. However, the machining table and tool head can automatically swivel in two directions between operations. Indexed 5-axis machining is great for manufacturing housings, jigs and fixtures. It falls somewhere between 3-axis CNC milling and continuous 5-axis CNC machining in terms of speed, precision, and the ability to handle complex geometries.
In continuous 5-axis CNC machining, the cutting tool and the workpiece can rotate and move simultaneously during operation, saving time and allowing operators to manufacture intricate geometries with organic surfaces. Continuous 5-axis CNC machining offers improved surface finish, speed, and dimensional stability, but it has the highest cost-per-part.
Turning mill CNC centers are practically identical to CNC turning machines, with one exception — they’re equipped with CNC milling equipment. The workpiece is attached to a spindle that can either rotate or remain stationary while cutting tools remove material from it. By combining the elements of CNC lathe machines with milling tools, mill-turning CNC centers offer high levels of accuracy and geometric versatility, making them great for creating parts with loose rotational symmetries, such as camshafts or centrifugal compressors.
Not only do these types of 5-axis CNC milling machines offer greater accuracy when machining deeper parts and hardened materials, but they also offer higher yields and faster machining speeds. However, 5-axis machining is more expensive due to the specialized equipment necessary and the need for expert workers.
In recent years, with the widespread use of new technologies, new processes, and new materials, various types of carbon fiber, aluminum profiles, glass fiber, and other materials have been applied to various industries and fields. With the rapid rise of new energy vehicles and the demand for lightweight vehicles, domestic automakers are also expanding production and launching various intelligent models. At the same time, various new materials and new processes are being more widely used in new energy vehicles. Speed Master also seized the opportunity to better serve the automotive industry customers, combined with the production and processing needs of new energy vehicle parts, we designed a double-station gantry five-axis machining center, the machine tool adopts a double-station structure, one set of fixtures can be machined on five surfaces. The use of A and B double tables can achieve feeding on one table and machining on the other, achieving true uninterrupted machining.
