Why Choose 4-Axis & 5-Axis CNC Machining Services?

There’s a growing need to make super-detailed and complicated parts (like curves on multiple angles or deep hollow spaces). Traditional 3-axis CNC machining technology can’t handle these well, but multi-axis machines with spinning worktables can easily solve these problems!

5-Axis CNC Machining Advantages

1. Complex Shapes in One Setup
Cut multi-angle features like turbine blades (defects ↓26%)
2. Medical-Grade Finishes
Achieve Ra<0.4μm surfaces (bone implants ready)
3. Smart Cost Control
Use 1 fixture instead of 12 (aircraft parts)
Deliver complex molds in 4 days vs 7 days

4-Axis CNC Machining Benefits

1. Enhanced Rotation Efficiency
Machine gears/shafts in one clamp
CNC factories lack rapid prototype tooling expertise
Separate vendors create tolerance mismatches (e.g., 3D printed jigs vs. molded parts)

Industry Applications of 4-Axis & 5-Axis CNC Machining Services

According to statistics, enterprises adopting multi-axis precision machining solutions have reduced repetitive fixture setups by 70% on average and shortened production cycles for complex components by over 35%. Among the global TOP 10 medical device suppliers, 9 have integrated 5-axis machining into their core processes.

Machining Tolerance Standard

This table outlines First Mold’s 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 Type	Tolerance Range	Application	Description
Dimensional Tolerance	±0.005 mm (±0.0002″) to ±0.1 mm (±0.0039″)	General parts with standard precision	Standard dimensional tolerances, suitable for most general machining tasks.
Geometric Tolerance	±0.01 mm (±0.0004″) to ±0.05 mm (±0.002″)	Complex parts needing precise geometry	Controls the form, orientation, location, and runout of features.
Straightness	0.005 mm (0.0002″) to 0.02 mm (0.0008″)	Components requiring straight edges	Ensures that a surface or axis is perfectly straight.
Flatness	0.005 mm (0.0002″) to 0.03 mm (0.0012″)	Parts needing a flat surface	Ensures the part’s surface does not deviate from the ideal flat plane.
Cylindricity	0.01 mm (0.0004″) to 0.05 mm (0.002″)	Cylindrical parts with strict tolerances	Controls the roundness and straightness of cylindrical surfaces.
Concentricity	0.01 mm (0.0004″) to 0.03 mm (0.0012″)	Parts where concentricity is crucial	Ensures that features (e.g., holes, shafts) are aligned within a common centerline.
Perpendicularity	0.01 mm (0.0004″) to 0.05 mm (0.002″)	Parts needing precise perpendicular surfaces	Ensures that features are exactly perpendicular to each other.
