Henan San Kuang Machinery Technology Co., Ltd., established in 2014 with a modern factory spanning 10,000–30,000 square meters, is a trusted manufacturer of precision machined parts. Our Custom Machined Components for Robotic Arms are crafted from premium 7075 aluminum alloy and finished with a durable anodized coating, delivering exceptional strength-to-weight ratio and corrosion resistance. These components are engineered to meet the demanding requirements of modern robotic systems, ensuring reliable performance, long service life, and seamless integration. With an annual export value of US$2.5–5 million and a team of 51–100 skilled employees, we are your reliable partner for high-quality robotics parts.
Key Features & Technical Specifications
- Material Excellence: 7075 aluminum alloy, known for its high tensile strength (up to 570 MPa) and excellent fatigue resistance, ideal for robotic arm joints and structural parts.
- Anodized Coating: Hard anodized finish (Type III optional) provides enhanced wear resistance, surface hardness (up to 60 HRC), and protection against corrosion and chemicals.
- Precision Machining: CNC turning, milling, and drilling with tolerances as tight as ±0.005mm, ensuring perfect fit and repeatability.
- Customizable Design: We accept custom drawings (STEP, IGES, PDF) for non-standard components, with flexible MOQ and lead times.
- Versatile Applications: Suitable for articulated robot arms, SCARA robots, collaborative robots (cobots), and industrial automation systems.
- Surface Finish Options: Clear anodized, black anodized, or custom colors (e.g., blue, red, green) for aesthetic or functional needs.
- Quality Assurance: 100% inspection with CMM, coordinate measuring machines, and surface roughness testers. Certifications include ISO9001, ISO14000, OHSAS18001, and more.

Benefits for Your Robotic System
- Enhanced Payload Capacity: Low weight (2.8 g/cm³ density) allows robots to handle heavier payloads or operate faster.
- Extended Service Life: Anodized layer resists wear, scratches, and environmental corrosion, reducing maintenance frequency.
- Improved Accuracy: High dimensional stability and tight tolerances ensure consistent positioning and repeatability.
- Cost-Effective: 7075 aluminum offers a balance of performance and cost compared to titanium or carbon fiber.
- Easy Integration: We can add threaded holes, keyways, or mounting features as per your robotic arm design.

Frequently Asked Questions (FAQ)
Q1: What is the typical lead time for custom machined components?
A: Lead time depends on complexity and quantity. Generally, prototype orders take 7–15 working days, and mass production takes 15–30 working days. Rush orders can be arranged upon request.
Q2: Can you provide anodized coating in colors other than clear or black?
A: Yes, we offer custom anodized colors (e.g., red, blue, gold, green) with minimum order quantity (MOQ) requirements. Please specify your Pantone or RAL code.
Q3: Do you offer free samples for testing?
A: Yes, we provide free samples for standard parts or custom prototypes. However, the customer is responsible for shipping costs. Please contact our sales team for approval.
Q4: What file formats do you accept for custom designs?
A: We accept STEP, IGES, STP, PDF, DWG, and DXF files. Our engineers can also provide design optimization suggestions.
Q5: Are your components compatible with all major robot brands?
A: We design and manufacture based on your specific dimensions and interface. As long as you provide the original part drawing or sample, we can replicate or improve the design.
Q6: What is the maximum size of parts you can machine?
A: Our CNC machines can handle parts up to 2000mm × 1000mm × 600mm. Larger parts may require special arrangements.
Q7: How do you ensure the quality of the anodized coating?
A: We perform salt spray tests (ASTM B117) for corrosion resistance, thickness measurement, and hardness tests. Anodizing is done in-house to control quality.
Q8: Do you offer any warranty on your products?
A: Yes, we provide a standard 12-month warranty against manufacturing defects. Extended warranty options are available upon request.
