What Is Multi-axis Machining Center?

Pulished on Dec. 23, 2023

Multi-axis machining is a manufacturing process that involves tools that move in 4 or more directions and are used to manufacture parts out of metal or other materials by milling away excess material, by water jet cutting or by laser cutting.


What Is Multi-axis Machining


Multi-axis machining is popular for manufacturers across various industries due to its speed, efficiency, and ability to create products with very few errors. At Leichman manufacturing, we offer precision multi-axis machining solutions that can meet the highest industry standards and expectations.

Multi-Axis Machining Center


Multi-axis machining center is a sophisticated manufacturing process utilizing machinery capable of movement in four or more directions. This technique finds extensive applications in producing specific parts or shaping objects from materials like metal.


There exist three primary types of multi-axis machining:


3-Axis CNC Machining


Among these types, 3-axis machining stands as the most straightforward. It involves a stationary workpiece around which a spindle moves along the X, Y, and Z axes. Generally, 3-axis machining is suitable for handling 2D or 2.5D geometries in products. Although it is possible to machine all six sides of a workpiece with 3-axis machining, each side demands a potentially expensive fixture setup.


4-Axis CNC Machining


In 4-axis machining, an additional A-axis supplements the X, Y, and Z axes. While the former axes enable linear spindle movement, the A-axis rotates the workpiece, granting access to other facets of the object. Particularly in vertical machining applications, these systems often pivot the spindle along the Z-axis. The inclusion of this extra axis reduces the necessity for multiple fixture setups, rendering 4-axis machining more cost-efficient compared to 3-axis systems.


5-Axis CNC Machining


5-axis machining involves the rotation of either the C- and A-axis or the B- and C-axis. In these configurations, either the spindle or workpiece can rotate. There are two types of 5-axis machines: the 3+2 axis machines, which independently rotate two axes, and the fully continuous machines that simultaneously rotate both axes. Both variations of 5-axis machines excel in shaping intricate 3D forms from workpieces.


Advantages of Multi-Axis Machining


Multi-axis machining offers a multitude of advantages that cater to various applications:


- Enhanced Part Accuracy: By enabling the production of intricate parts in a single setup, multi-axis machining reduces processes and machines needed, resulting in heightened geometrical precision.


- Streamlined Complex Part Production: Multi-axis machines excel in crafting highly intricate 3D shapes by employing additional movements to create diverse angles and arcs.


- Prolonged Tool Lifespan: Constant tilting of the tool or table in multi-axis machining extends the tool's life while maintaining an optimal cutting position.


- Superior Surface Finish: With shorter cutting tools that minimize vibrations at high speeds, multi-axis machines deliver superior surface finishes.


- Reduced Labor Costs: The automation and diminished need for manual re-fixturing in multi-axis machines decrease manual labor requirements, consequently lowering costs.


- Minimized Scrap/Waste: The efficiency of multi-axis machining results in less waste compared to alternative manufacturing methods.


- Mass Production Capability: Enhanced efficiency and repeatability enable the mass production of various products, facilitating scalability in manufacturing operations.


Applications and Industries


The advantages inherent in multi-axis machining have led to its widespread use across various industries, including:


Aerospace: The intricate nature of aerospace products and components necessitates the accuracy and efficiency provided by multi-axis machining for their production.


Aviation: Similar to the aerospace sector, applications within aviation demand precision, accuracy, and efficiency—qualities readily fulfilled by multi-axis machining processes.


Automotive: The intricate designs of automotive parts can be efficiently produced in large quantities using multi-axis machining, catering to the needs of automakers.


Defense: The defense industry relies on dependable processes like multi-axis machining to ensure consistent quality and efficiency in the production of its diverse products and components.


Medical: Multi-axis machining plays a crucial role in developing high-quality medical tools and devices, meeting the stringent requirements for precision and accuracy in this sector.
