Custom CNC Ordering Guide

Unlock Precision Manufacturing: Your Fully Custom CNC Ordering Guide

Navigating custom CNC machining can be complicated, but it doesn't necessarily mean it. At Greatlight, we simplify advanced manufacturing by combining cutting-edge five-axis CNC technology with deep engineering expertise. Whether you are making aerospace components or mass-producing medical equipment, this guide reveals the ordering process to ensure your project utilizes precision, efficiency, and affordability.

Why five-axis CNC machining?

Five-axis CNC machining allows simultaneous cutting from five directions, making complex geometries tighter and superior surface effect. Unlike 3-axis machines, it reduces settings, minimizes errors and accelerates production - used in complex designs in industries such as aerospace, automotive and robotics. At Greatlight, our advanced equipment handles all work from titanium to thermoplastics with an accuracy of ±0.01mm.

Step by step: Order custom CNC parts

1. Define your requirements

Start with clarity:

• CAD model: Upload 3D files (steps, IGES, X_T) and 2D graphs (PDF, DWG) to specify sizes.


• Material selection: Choose from over 300 metal/alloys (aluminum, stainless steel, inconel) and engineering plastics. Need guidance? Our engineers recommend materials based on strength, corrosion resistance and cost.


• Quantity and timetable: Specify volume (1-10,000+ units) and deadline.


• Completion and tolerance: Pay attention to surface treatment (anodized, powder coating) and critical tolerances (typical ±0.025mm).

2. Request a Quote (RFQ)

Submit your specifications through Greatlight's online portal. include:

• Technical drawings with GD&T annotation.


• Material certification (e.g., AMS, ASTM).


• Quantity layer discount.
  
  We responded with competitive pricing within 4-8 hours.

3. Manufacturing Design (DFM) Review

Our engineers analyze your design professional rationality:

• Optimize geometry to reduce machining time/cost.


• Propose alternatives for difficult-to-computing functions.


• Mark potential pressure points or tool conflicts.
  
  Make real-time adjustments through email or video phone collaboration.

4. Production and quality control

Once approved:

• Processing: Five-axis centers operate 24/7 under ISO 9001 protocol.


• Process check: Laser scanner and CMMS verify dimensions in critical stage.


• Final inspection: Complete laboratory report with dimensional data and material certificate.

5. Post-processing and completion

Select value-added services:

• Surface finish: Bead blasting, electropolishing, passivation.


• coating: Ceramic, Teflon or ENP plating.


• assembly: Drilling, tapping or kit.
  
  All services are processed internally to ensure consistency.

6. Rapid transportation and logistics

Parts are shipped worldwide within 2-15 days (depending on complexity). receive:

• Real-time tracking.


• Custom packaging to prevent transit damage.


• Emergency modifications are supported after delivery.

Why collaborate with Greatlight?

• Accurate speed: Compared with traditional CNC, the five-axis technology cut time is 40%.

FAQ: Your custom CNC question has been answered

Q: Which file formats do you accept for CAD models?

A: We support 3D file steps, IGES, X_T, SLDPRT and Parasolid, while PDF/DWG is used for 2D graphs.

Q: Can you handle micro cache or ultra-tight tolerances?

Answer: Absolute. Our five-axis machines can be reduced to ±0.005mm. Miniature arrangements of parts <5mm are professional.

Q: How to ensure the quality of medical/aerospace parts?

A: We perform material traceability, CMM checks for each ASME Y14.5 and according to the documentation results of ISO 13485/AS9100. Certification is available upon request.

Q: What is the typical turnover of 100 aluminum parts?

Answer: The standard delivery time is 5-7 days of processing + 1-3 days. Accelerated options available (50% faster).

Q: Can you suggest cost-saving design adjustments?

A: Yes - Our DFM analysis includes recommendations for increasing rounded radius using standard tool sizes or adjusting the undercut to reduce 25%.

Q: Do you assist in choosing materials for high-thermal applications?

A: Our engineers guide you toward alloys such as Inconel 718 or Ti-6Al-4V at a high temperature, sharing modulus and fatigue data.

Q: Is post-processing mandatory?

A: No, but it enhances durability and aesthetics. Unfinished parts have a processed finish (usually RA 1.6–3.2μm).
