Simultaneous 5-Axis vs. 3+2 Axis Machining:Detailed Comparison

Metal parts are moulded on a 5-axis CNC machine, demonstrating the precision and versatility of advanced machining technology.

In CNC machining, Simultaneous 5-Axis and 3+2 Axis machining are the two main types. Each has its traits and range of uses. Simultaneous 5-Axis can machine on five independent axes at once. It can handle very complex shapes and is best for high-end precision machining. 3+2 Axis adds two rotary axes to the traditional three-axis machining. Although it can’t do simultaneous machining on all five axes, it still offers better contact angles and higher efficiency for certain complex parts.

Next, Yonglihao Machinery will describe the specific uses, benefits, and selection guide for Simultaneous 5-Axis and 3+2 Axis machining. This will help you better understand these two machining technologies and find better solutions for your projects.

Detailed Comparison of Simultaneous 5-Axis vs. 3+2 Axis Machining

Simultaneous 5-axis vs. 3+2 Axis CNC machining each has clear advantages. The choice depends on the specific machining needs, budget, and desired accuracy and efficiency.

Simultaneous 5-Axis CNC Machining

5-Axis CNC machining is advanced. It can machine in five axes at once. It can handle complex shapes and do precise machining in many positions. This improves machining efficiency and quality. The Simultaneous 5-Axis CNC machine does high-precision machining of complex parts. It does this by moving three linear axes, X, Y and Z, and two rotary axes (e.g., the A-axis and the B-axis).

Advantages

Accuracy: Provides extremely high machining accuracy, especially for complex shapes and small features.

Speed: It can complete multi-face machining in one pass. This greatly cuts workpiece changeover time and boosts machining efficiency.

Complex Shape Handling Capability: Capable of machining a variety of complex geometries, providing greater machining flexibility.

3+2 Axis CNC machining

3+2 Axis CNC machining is also called three-plus-two-axis machining. It combines traditional three-axis machining with two extra rotary axes. But, it does not control them simultaneously. This method expands the range and flexibility of machining. It does this by enabling the workpiece to be machined in five-facing positions. This is done using rotary axes fixed at specific angles.

Advantages

Cost-effective:3+2 Axis CNC machining is usually cheaper than full 5-axis machining. So, it’s ideal for projects with tight budgets.

Simplified programming: Machining does not need control of all five axes at once. So, programming is simple to learn and use. This makes it less difficult to operate.

FAQ

Simultaneous 5-Axis machining enables precision machining in five axes at once. It is good for complex shapes and provides higher machining accuracy and speed. 3+2 Axis machining adds two rotary axes to the traditional three. But, they are not operated at the same time. It is suitable for parts with simpler requirements at a low cost.

Simultaneous 5-Axis machining: These machines are used in aerospace, automotive, and medical device manufacturing. They are also used in consumer electronics. They are especially used for applications needing high precision and complex shape machining.

3+2 Axis Machining: For simpler aerospace parts, use standard car parts. Also, for general industry and some basic consumer electronics.

Budget is important for deciding whether to use Simultaneous 5-Axis or 3+2 Axis machining. Simultaneous 5-Axis machining costs more to use and operate. It is good for projects that need high accuracy and complexity. If the budget is limited and the machining needs do not require the high precision of Simultaneous 5-Axis machining, then 3+2 Axis machining will be a cheaper option. It will meet most of your machining needs at a lower cost.
