Henan San Kuang Machinery Technology Co., Ltd., established in 2014 with a factory spanning 10,000–30,000 square meters and an annual export value of US$2.5–5 million, proudly presents our CNC Machining Aluminum Parts with 0.005mm Tolerance and 63A Hardness. These precision components are engineered to meet the most demanding industrial requirements, leveraging our state-of-the-art CNC equipment and rigorous quality control systems. With over a decade of expertise and a dedicated team of 51–100 professionals, we deliver aluminum parts that combine exceptional dimensional accuracy, consistent hardness, and reliable performance across diverse applications.
Our CNC machining aluminum parts are designed for customers who demand uncompromising precision and durability. The 0.005mm tolerance ensures that every part fits perfectly into complex assemblies, reducing rework and enhancing overall system efficiency. The 63A hardness level provides excellent wear resistance and structural integrity, making these parts suitable for high-stress environments. Whether you need prototypes, low-volume production, or high-volume runs, our flexible manufacturing capabilities can accommodate your specific requirements.
Key Features & Technical Specifications
- Ultra-Precision Tolerance: ±0.005mm (0.0002 inches) achieved through advanced CNC machining centers and calibrated tooling.
- Consistent Hardness: 63A on the Rockwell A scale, providing optimal balance between machinability and wear resistance.
- High-Grade Aluminum Alloys: Available in 6061, 7075, 2024, and other alloys to suit your mechanical and corrosion resistance needs.
- Surface Finishing Options: Anodizing (clear, black, color), powder coating, bead blasting, and chemical film (Alodine) – all customizable.
- Complex Geometries: 5-axis CNC capability allows for intricate contours, undercuts, and tight internal features.
- Quality Assurance: Every batch undergoes 100% inspection using CMM (Coordinate Measuring Machine), optical comparators, and hardness testers.
- Certifications: Our facility is ISO9001, ISO14000, OHSAS18001, and other international standards certified – ensuring consistent quality and environmental responsibility.
- Flexible Lot Sizes: From single prototypes to 100,000+ production runs, with lead times optimized for your schedule.

Frequently Asked Questions (FAQ)
-
Q: What aluminum alloys do you recommend for achieving 63A hardness?
A: We commonly use 6061-T6 and 7075-T6 alloys, which can achieve the 63A hardness range through proper heat treatment. Other alloys are available upon request. -
Q: Is the 0.005mm tolerance achievable for all part sizes?
A: The tolerance applies to most features within our standard machining envelope (up to 1200mm). For very large or thin-walled parts, we may specify slightly looser tolerances; please consult our engineers for your specific design. -
Q: Can you provide surface finishing services like anodizing?
A: Yes, we offer a wide range of surface finishes, including clear anodizing, hard anodizing, powder coating, and chemical conversion coating. These can be applied to enhance corrosion resistance, wear resistance, or aesthetics. -
Q: What is the typical lead time for a prototype order?
A: For standard prototypes, lead time is approximately 7–10 working days, depending on complexity and current workload. Expedited services are available for an additional fee. -
Q: How do you ensure the parts meet the specified hardness?
A: We perform 100% hardness testing on critical features using calibrated Rockwell hardness testers. A test report can be provided with each shipment. -
Q: Do you offer any warranty or quality guarantee?
A: Yes, we stand behind our work. All parts are covered by our standard quality guarantee: if a part does not meet the agreed specifications, we will replace or rework it at no extra cost. -
Q: What is the minimum order quantity (MOQ) for these parts?
A: We have no fixed MOQ for standard parts. For custom designs, we can accommodate both single-piece prototypes and high-volume production runs. -
Q: How can I get a quote?
A: Simply send us your 2D/3D drawings (STEP, IGES, PDF, etc.) along with your material, tolerance, finish, and quantity requirements. We will respond with a competitive quote within 24 hours.
