Case Study: CNC Machining & Anodizing Solution for a Complex Aluminum Assembly
A two-piece CNC machining strategy helped solve shape-transition, anodizing, and final assembly challenges.
The Challenge
Integrating the circular and square sections into a single CNC-machined part was technically possible, but it would have required significantly more machining time and material removal, resulting in much higher manufacturing costs. More importantly, because every surface was visible, conventional anodizing hanging methods would inevitably leave hanging marks on the cosmetic surfaces.
Solution
To improve manufacturability, we redesigned the production process by machining the two components separately. M5 threaded holes were incorporated into both parts, allowing us to develop dedicated M5 anodizing fixtures that securely held each component during surface treatment. This eliminated visible hanging marks while maintaining consistent anodizing quality across all exposed surfaces.
Result
After anodizing, the two components were assembled using custom M5 set screws, creating the appearance of a single integrated product. This approach significantly reduced machining costs, improved production efficiency, and delivered a clean, high-quality anodized finish without compromising the product's appearance.
- Project Outcome
- Better tool access
- Cleaner Anodized Appearance
- Reliable final assembly

Through optimized toolpaths, calibrated equipment, and engineering oversight, HRCCNC reduces production risk and maintains stable precision in the machining of complex custom parts.
How Much Does CNC Machining Cost?
CNC machining costs range from $50–$150 per hour, but the total cost depends on multiple factors rather than a fixed price. Key cost drivers include material type (e.g., stainless steel or titanium alloy), part complexity, required tight tolerances, surface finish, setup time, quantity, and overall lead time for prototype CNC machining services versus high-volume CNC machining services. Prototype custom parts may cost a few hundred dollars per part, while scaled production reduces the per-unit price through setup, distribution, and process efficiency.

What Our CNC Machining Clients Say About Us?
How Does the CNC Machining Process Work at HRCCNC?
Step 1: CAD Design Preparation
Customers upload CAD files through our online CNC machining service platform for immediate engineering review. Our experienced engineers provide free Design for Manufacturability DFM feedback, evaluating tolerances, material selection, wall thickness, and feature feasibility to prevent production risks. This early-stage review improves cost efficiency, reduces lead time, and ensures precision CNC machining services deliver accurate custom CNC-machined parts.
Step 2: Converting CAD to CNC Program (G-code)
After design approval, CAM software generates optimized toolpaths and converts the CAD model into G-code instructions. The program defines tool type, spindle speed RPM, feed rate, coolant flow, and coordinate movements required for the manufacturing process. Simulation verifies collision avoidance, dimensional accuracy, and cycle time before machining begins, ensuring stable precision CNC machining services.
Step 3: Machine Setup & Tool Selection
Our team at HRCCNC selects cutting tools based on material and feature requirements, such as carbide end mills for aluminum alloy and steel alloy, indexable inserts for CNC turning, and high-precision drills or reamers for holes. Fixtures, soft jaws, and calibrated setups ensure rigidity and repeatability during machining. Proper setup control supports tight tolerances and consistent output across both prototype and high-volume CNC machining services.
Step 4: Precision Cutting & Finishing
The machining process starts with roughing to remove bulk material, followed by finishing passes to achieve final dimensions and surface quality, typically Ra 1.6–3.2 μm or lower, achieved through grinding or polishing. After cutting, post-machining steps such as deburring, anodizing, powder coating, passivation, or plating are applied as required. This workflow ensures high-quality custom CNC parts with controlled surface finish and dimensional stability.

FAQs
What Does a CNC Machine Operator Do?
A CNC machine operator sets up machines, loads materials, monitors cutting operations, and verifies finished machining parts against specified tolerances. The operator follows programmed G-code instructions, inspects dimensions using calibrated tools, and ensures precision CNC machining services produce consistent custom CNC-machined parts according to quality standards.
What is G Code in a CNC Machine?
G-code is a fundamental programming language used in CNC machining services to control machine movements and operations. It defines tool paths, spindle speed (RPM), feed rate, coolant flow, and coordinate positioning, enabling precision CNC machining services to produce accurate, repeatable custom CNC-machined parts.
How to Program a CNC Machine?
Programming a CNC machine involves creating a CAD design, generating toolpaths using CAM software, and converting them into G-code instructions for machining. The program defines tool selection, spindle speed, feed rate, and coordinate movements to guide the manufacturing process. Simulation and verification ensure precision CNC machining services produce accurate custom CNC-machined parts before actual cutting begins.
When Did CNC Machining Start?
CNC machining began developing in the late 1940s and early 1950s as numerical control systems were introduced for aerospace manufacturing. In 1952, the Massachusetts Institute of Technology (MIT) unveiled the first CNC milling machine, which used punch cards for programming. The integration of computers into machine tools during the 1960s transformed numerical control into modern CNC machining, enabling automated precision CNC machining services for complex, custom parts across industries.
How Many Axis in a CNC Machine?
CNC machines commonly operate in 3-axis, 4-axis, or 5-axis configurations, depending on the complexity of the custom part. A 3-axis CNC machining service moves along X, Y, and Z directions, while a 4-axis adds rotational movement, and a 5-axis enables simultaneous multi-directional machining for complex geometries. Advanced 5-axis CNC machining services reduce setup time, improve precision, and support the production of intricate aerospace, medical, and industrial components.
Is there a minimum order quantity (MOQ) for custom CNC parts?
No, our custom CNC machining services do not require a strict minimum order quantity. We offer prototype CNC machining for single-part orders and high-volume CNC machining for scaled production. This flexibility allows engineers to validate designs before committing to larger manufacturing runs.
Can I request changes to my design after the quote or during production?
Yes, you can request design changes after receiving a quote, and our engineering team will review the updated CAD file and provide revised pricing and lead time. If production has already started, we assess the machining stage and material status before confirming feasibility and cost impact. Early communication ensures precision CNC machining services remain efficient and avoid unnecessary delays or material waste.
What payment options are available for online CNC orders?
We accept secure international payment methods, including bank transfer (T/T), major credit cards, and other agreed commercial payment terms for qualified customers. Payment terms are confirmed during the quotation to align with the order size and production stage. This transparent payment structure supports both prototype and high-volume CNC machining services for global customers.
What happens if my design has potential manufacturability issues?
If your design has potential manufacturability issues, our engineering team provides free Design for Manufacturability DFM feedback before production begins. We identify tolerance conflicts, thin walls, sharp internal corners, or material compatibility issues that may affect the precision of CNC machining services. This early review helps optimize the manufacturing process, reduce cost, and ensure your custom CNC-machined parts meet performance and quality requirements.
