1. Advanced CNC Solutions for Complex Parts

Our Complex CNC Machining Services are built for the most geometrically demanding parts. From undercuts and deep cavities to angled ports and freeform surfaces, we use 4- and 5-axis machining to achieve precision, repeatability, and clean finishes.

• Freeform surfaces & organic geometries
• Multi-axis tool path programming
• Single-setup machining for high accuracy

2. Application Scenarios for Complex CNC Parts

● Aerospace Components

Titanium and aluminum alloy parts with internal channels, compound angles, and thin walls—machined with precision and minimal distortion.

● Automation & Robotics

Sensor brackets, arm joints, camera mounts, and housing structures that require multiple reference surfaces and tight alignment tolerances.

● Medical & Surgical Devices

Complex stainless-steel handles and internal cavities for custom tools, implants, and diagnostics equipment.

3. Case Study: Multi-Face CNC Machined Sensor Housing

Project Overview

A European automation integrator required 1,200 aluminum sensor housings with five machined surfaces, including angled slots and threaded holes on three axes. Tolerance: ±0.01mm. Surface: bead blast + black anodizing.

How We Delivered It

• ① Process Planning: Broke down the part into five machining orientations and simulated tool access for collision avoidance.
• ② Custom Fixture Design: Designed modular soft jaws to allow secure re-positioning with zero damage.
• ③ 5-Axis Machining: Combined operations using one fixture + rotary table to reduce setups and errors.
• ④ Optical Measurement: Used non-contact CMM for compound angles and surface position verification.
• ⑤ Finishing: Uniform bead blasting and anodizing, with cosmetic QC for every 50 pieces.

4. How We Handle Geometric Challenges

● CAD/CAM Collaboration

We accept native CAD files (STEP/IGES/SolidWorks) and optimize tool paths to avoid chatter, improve tool life, and ensure smooth transitions in freeform areas.

● Simulation Before Cutting

Complex parts are simulated in CAM software to check reachability, rigidity, and surface flow—reducing trial-and-error and saving time.

● Integrated QA Strategy

Dimensional and positional tolerances are checked not only on machined features but also across multiple reference planes for assembly-critical parts.

5. CNC Capability FAQs for Complex Parts

● Can you machine complex parts from difficult materials?

Yes—we regularly handle stainless steel, titanium, magnesium, and copper alloys with advanced tooling and coolant systems.

● Do you support rotating part geometries or off-axis holes?

Yes. Our multi-axis equipment supports turning-milling hybrids and eccentric drilling with positional accuracy.

● Can you hold tolerance across multiple sides?

Absolutely. Using single-setup 5-axis machining or precision repositioning fixtures, we ensure tolerance stack-up is controlled.

6. Confidentiality & Collaboration Guaranteed

All complex machining projects are protected under NDA. We assign senior engineers to follow complex jobs from simulation to delivery, ensuring consistent technical communication.
