Precision CNC Machining at Scale — Tolerances You Can Trust, Deadlines You Can Depend On
Modern manufacturing demands extreme precision, short lead times, and repeatable accuracy — all without compromising on cost or quality. Harbor Labs enables this by providing end-to-end CNC machining solutions across an international network of certified partners. We manage everything from design review and material selection to tooling, post-processing, and quality assurance, helping you scale production while reducing friction in your supply chain. Whether you need 5-axis milling, Swiss turning, EDM, or rapid prototyping, we have the capabilities to deliver.
What Is CNC Machining?
Computer Numerical Control (CNC) machining is a subtractive manufacturing process in which pre-programmed computer software controls the movement of tools to shape a workpiece.
- Delivers exceptional accuracy for complex parts
- Suitable for both low-volume prototyping and large-scale production
- Supports a wide range of materials — metals, plastics, and composites
- Enables consistent, repeatable quality
- Ideal for components requiring precise geometry and surface finish
Types of CNC Machining We Offer
- 3-Axis, 4-Axis, and 5-Axis Milling
- CNC Turning / Swiss Turning
- Wire EDM and Sinker EDM
- CNC Grinding and Lapping
- CNC Drilling and Tapping
- Surface Finishing (Anodizing, Plating, Coating)
