What is the difference between 5-axis machining and 5-axis turn milling?

What is five-axis machining?

Five-axis machining can usually carry out five-axis simultaneous machining, and is supported by CNC system, servo system and RTCP function. Five-axis machining has excellent performance in the machining of curved surfaces, highly complex shapes, special shapes, hollow parts, angled holes and bevel cuts.


What is five-axis turning and milling?

Five-axis milling and turning combined with turning and milling can realize a variety of different processing through the linkage of two processing. This machining allows drilling, tapping, milling, and turning of external and internal holes.

Five-axis turning-milling machining is a representative technology of multi-axis machining. The five-axis turning-milling compound machining center is the carrier of the five-axis turning-milling compound technology. The five-axis turning-milling machining center is a general term for a machine tool with turning as its main function and integrated milling and boring. It has at least three linear feed axes and two circular feed axes, and is equipped with an automatic tool change system. The turning and milling compound machining center is developed on the basis of the three-axis lathe center, which is equivalent to the complex of the turning center and the machining center. It is a composite processing technology developed in the 1990s. Five-axis turning and milling compound machining is an advanced machining technology that integrates modern advanced control technology, precision testing technology and CAD/CAM application technology on the basis of traditional mechanical design technology and precision manufacturing technology.

Generally, five-axis turning and milling is used to manufacture parts that require turning and milling, as well as precision machined parts that require high dimensional accuracy.


What are the advantages of five-axis machining?

Five-axis machining or five-axis milling is excellent when machining complex shapes and high-precision objects. Because the machine tool or the probe can approach the part from any direction after one clamping. Five-axis CNC machining has many significant advantages.

Five-axis milling

High precision

The precision of five-axis CNC milling is very high, as it requires minimal setup. Additional installations will cause more errors.

With the help of five-axis machining technology, the precision problem that the complex angle of the workpiece needs to be repositioned many times is solved. Not only the processing time is shortened, but the processing accuracy is also greatly improved.

Excellent surface finish

The configuration of the five-axis machining center will help create a high-quality finish surface. The part is positioned closer to the tool of the five-axis machine. And the last two axes can use quick-release tools, which do not generate a lot of vibration, resulting in a high surface finish.

high productivity

Five-axis machining will effectively shorten CNC machining time and auxiliary machining time. The five-axis CNC machine tool has high spindle speed, large feed range and strong cutting ability. Due to the rapid movement and positioning of 5-axis machining and high-speed cutting, the turnaround time of semi-finished products is reduced, while the production efficiency and accuracy are improved.


What are the advantages of five-axis turning-milling machining?

The five-axis turning-milling machine tool is a machine tool that has both the turning function of the turning center and the milling function of the CNC machining center, and can perform both functions on one machine tool.

Five-axis mill-turn machining has many other significant advantages.

1.Reduction of production line and processing volume

The five-axis turning-milling compound machining can carry out the complete machining process of the workpiece. Complete machining reduces production lines considerably. Since all machine tasks are centralized in one working location, production management and planning is simplified. Production planning is no longer required. The complexity is that the workpiece is the biggest advantage of five-axis turn-mill machining.

With the reduction of production lines, the number of products being processed is relatively reduced.

2.Reduce the base change and improve the accuracy.

Process integration improves processing efficiency. Since the part needs to be clamped once during the entire machining process, it is easy to ensure machining accuracy.

3.Double spindle, higher efficiency

Usually, the five-axis turning-milling compound machining center is equipped with dual power heads, dual spindles and dual tool holders, which can realize the simultaneous processing of multiple tools and effectively improve the processing performance.

in conclusion

The main difference between 5-axis machining and 5-axis turn-mill machining is the type of machining and the workpiece.

The main function of five-axis machining is milling, and the biggest advantage is the machining of complex shapes and complex special parts that require high precision.

The main function of the five-axis turning-milling compound machining is turning, and the secondary function is milling. There is a great advantage when the main structure of the workpiece is circular. Five-axis turning-milling machining center can perform turning and milling at the same time


Application field

Five-axis machining is often used in aerospace precision machining, especially for parts with free-form surfaces. Such as airframe parts, turbine parts, impellers, etc.

The purpose of five-axis turning-milling compound machining is to improve product quality and shorten manufacturing cycle. Therefore, the technology has a dominant position in the fields of automation equipment, medical equipment, communication, and auto parts manufacturing, especially in the processing of complex parts.
