Large CNC Parts

Product Overview

In industries demanding oversized components with micron-level accuracy—from aerospace to energy infrastructure—Large CNC parts are the backbone of innovation. As an ISO 9001 :2015 certified factory, we specialize in machining complex geometries up to 5,000mm length × 2,700mm diameter with tolerances as tight as ±0.025mm (ISO 2768-f standard)

Technical Capabilities: Redefining Scale and Precision

Our facility houses state-of-the-art CNC equipment engineered for massive components:

• Max Part Dimensions: 4,000mm × 1,500mm × 600mm (CNC Milling) / Ø500mm × 1,000mm (Turning)

• Tolerance Control: ±0.025mm linear dimensions, hole/shaft diameters; surface roughness ≤3.2Ra

• Large-Part-Specific Tooling: Magnetic workholding systems, modular fixtures, and FARO laser trackers for in-process validation

• Material Versatility: Steel alloys, aluminum, hardened metals, engineering plastics (e.g., PEEK, PTFE)

Custom Workflow: From Prototype to Production

We streamline custom large CNC parts manufacturing through a 4-stage process:

1.Design Consultation

• CAD/3D file analysis (STEP/IGES/PDF), manufacturability feedback

• Reduced redesign costs, optimized for CNC efficiency

2.Pre-Production

• Rapid prototyping (1-3 days), tolerance simulation

• Risk mitigation before full-scale production

3.Machining

• Multi-axis milling/turning, 5-axis contouring for complex geometries

• Single-source solution; no outsourcing delays

4.Quality Assurance

• In-process FARO Arm Quantum checks, ISO 9001:2015 final inspection

• GD&T compliance per military (MIL-I-45208) and aerospace specs

Industry Applications: Where Scale Meets Critical Performance

Large CNC parts enable breakthroughs in sectors requiring uncompromising reliability:

• Oil & Gas: Pipeline valves, refinery components resistant to extreme pressure/temperature

• Aerospace: Landing gear couplers, helicopter frames (up to 40-ton load capacity)

• Transportation: Freight train bogies, ship engine mounts

• Energy: Wind turbine hubs, hydroelectric turbine shafts (5,000mm Z-axis travel)

Q:How fast can I receive a CNC prototype?

A:Lead times vary depending on part complexity, material availability, and finishing requirements, but generally:

• Simple prototypes: 1–3 business days

• Complex or multi-part projects: 5–10 business days

Expedited service is often available.

Q:What design files do I need to provide?

A：To get started, you should submit:

• 3D CAD files (preferably in STEP, IGES, or STL format)

• 2D drawings (PDF or DWG) if specific tolerances, threads, or surface finishes are required

Q:Can you handle tight tolerances?

A:Yes. CNC machining is ideal for achieving tight tolerances, typically within:

• ±0.005" (±0.127 mm) standard

• Tighter tolerances available upon request (e.g., ±0.001" or better)

Q:Is CNC prototyping suitable for functional testing?

A:Yes. CNC prototypes are made from real engineering-grade materials, making them ideal for functional testing, fit checks, and mechanical evaluations.

Q:Do you offer low-volume production in addition to prototypes?

A:Yes. Many CNC services provide bridge production or low-volume manufacturing, ideal for quantities from 1 to several hundred units.

Q:Is my design confidential?

A:Yes. Reputable CNC prototype services always sign Non-Disclosure Agreements (NDAs) and treat your files and intellectual property with full confidentiality.
