Core In 4 Axis & 5 Axis CNC Machining​

In 4 Axis and 5 Axis machining, the addition of one or two rotational axes to the worktable transforms the capability of our machines, allowing for the handling of significantly more complex parts. At FirstMold, we believe that the essence of 4 Axis and 5 Axis machining hinges on three critical factors: precision, efficiency, and cost.

While 4 Axis and 5 Axis CNC machining have become commonplace across machining facilities worldwide, FirstMold stands apart as the sole entity truly maximizing precision, efficiency, and cost control to their utmost potential. This achievement is rooted in the skilled craftsmanship of our staff and our company’s exceptionally rational workshop management.

Differences Between 3 axis, 4 axis and 5 axis CNC Machining

Feature 3 Axis CNC Machining 4 Axis CNC Machining 5 Axis CNC Machining
Complexity of Parts
Parts with relatively simple geometries.
More complex parts than 3 axis, including those needing cuts from the side.
extremely complex geometries, including simultaneous cutting from multiple angles.
Setup Times
Generally lower setup times for simple components.
Setup times increase slightly due to the additional axis, but reduce the need for multiple setups for complex parts.
Higher initial setup times due to complexity, but significantly reduces the need for multiple setups.
Production Speed
Fast for simple geometries but may require multiple setups for complex shapes
Faster than 3 axis for complex parts due to reduced need for multiple setups.
Fastest production times for complex geometries due to simultaneous 5-axis movement.
Precision & Accuracy
Good precision suitable for many applications.
Higher precision than 3 axis as it can approach the part from multiple angles
Highest precision and accuracy, capable of intricate details and tight tolerances.
Typical Applications
Flat surfaces, simple milling, and drilling operations.
Parts requiring machining on several sides, simple cams, and brackets.
Aerospace components, automotive prototypes, medical devices, and other highly complex parts.

Our Machining Tolerance Standard

4 axis or 5 axis CNC machined parts precision measurement

This table outlines our recommended tolerance standards. If you do not have specific tolerance requirements for your product, we will proceed with machining based on the standard class. Additionally, our colleagues will contact you promptly to analyze and recommend tolerances for your product based on our experience.

Tolerance Class General Tolerances (inches) General Tolerances (mm) Application
±0.127 mm
Suitable for general parts not subjected to high loads.
±0.0508 mm
Parts that must fit together with minimal gap or play.
±0.0254 mm
Aerospace components, medical devices, and other critical parts.
±0.0005" or tighter
±0.0127 mm or tighter
Applications where the slightest deviation cannot be tolerated, often requiring specialized equipment and processes.
