Different types of multi-axis machining centers provide various machining solutions and drive the continuous progress and innovation of manufacturing technology. Whether they are vertical, horizontal, or gantry-type machines, these multi-axis machining centers can meet different machining requirements, allowing for the machining of complex surfaces, simultaneous multi-axis movement, and high-precision machining. They provide more efficient and precise solutions for production and manufacturing across various industries, promoting the continuous evolution and innovation of manufacturing technology.
Types of CNC Multi-Axis Machining Centers
-
Vertical four-axis machining centers: These machines come in two forms - with a rotary table (A-axis) and with a swivel head (B-axis). The rotary table enables the workpiece to rotate horizontally, while the swivel head allows for tilting and rotation of the workpiece in the vertical direction. This type of machine is suitable for complex surface machining, enabling four-axis simultaneous movement and providing greater freedom in machining.
-
Horizontal four-axis machines: The worktable of these machines can rotate (B-axis), allowing for four-axis simultaneous movement. They are suitable for surface machining and can achieve multi-axis positioning and rotation of the workpiece during the machining process, enhancing flexibility and efficiency.
-
Five-axis machining centers: These machines have five axes of movement, typically including the X, Y, Z linear axes and two rotary axes (A-axis and C-axis). They enable free movement and positioning of the workpiece in all five axes, making them suitable for machining complex shapes, such as surface machining and multi-angle hole machining. Five-axis machining centers are widely used in aerospace, mold manufacturing, automotive industry, and other fields.
-
Head-head five-axis machines: This type, often gantry-type machines, features two spindle heads that can swing and rotate independently. They are suitable for machining complex surfaces, providing more cutting angles and machining freedom.
-
Head-table hybrid five-axis machines: These machines can be structured on C-type machines, gantry-type machines, and horizontal machines. They have independent spindle heads and worktables that can swing and rotate independently. This type of machine is suitable for different types of machine structures, offering greater flexibility and adaptability.
-
Table-table rotary worktable five-axis machines: These machines have two rotary worktables that can swing independently. The worktables have a wide installation range and can be installed on vertical, horizontal, and gantry-type machines. They provide more freedom in worktable rotation and machining flexibility.

Five-axis machining centers offer several advantages over three-axis machining centers. Firstly, they allow for the machining of deep cavities, reducing the risk of tool breakage by using short tools and enabling the processing of steep side walls or islands. Secondly, five-axis machining centers allow for the machining of undercut areas, reducing the use of forming tools and subsequent processes such as EDM and polishing. Additionally, they can shorten tool lengths, improve surface precision and quality, enhance tool rigidity, and prolong tool life. Finally, five-axis machining centers provide significant time efficiency by allowing for one-time workpiece clamping and positioning, reducing the time spent on repeated workpiece clamping and improving machining accuracy.
Conclusion
CNC multi-axis machining centers are essential tools in the manufacturing industry for producing complex and precise parts with high accuracy and efficiency. They offer advantages such as continuous production, faster delivery times, and the ability to handle multiple tasks simultaneously. When choosing a machine, factors such as the type of parts required, required precision, available workspace, and selecting a reputable manufacturer should be considered. These machines are particularly important in industries such as aerospace, automotive, and medical, where precision and accuracy are critical. The continuous advancement and innovation of multi-axis machining technology will further drive the development of the manufacturing industry.
