We offer custom CNC-turned automotive parts, meeting various structures, dimensions, tolerances, and surface finish requirements.
material selection
We source steel, aluminum, and brass from ISO-certified manufacturers. Each batch of raw materials comes with a test report, and we match materials according to the intended use to ensure reliable and traceable part performance.
Core Machining Capabilities
CNC Turning
We use CNC lathes to machine the outer diameters and inner bores of automotive parts, ensuring a roundness tolerance of ≤ 0.003 mm and a coaxiality tolerance of ≤ 0.005 mm.
CNC Milling
We use five-axis milling machines to machine end faces and keyways, achieving a surface roughness of Ra 0.8–1.6 μm and a dimensional accuracy of ±0.005 mm.
Thread Cutting
We utilize CNC thread cutting machines to produce internal and external threads with precisions reaching 6H/6g, ensuring a higher degree of engagement.
Surface Treatment
We offer passivation, anodizing, electroplating, and PVD coating processes to enhance wear and corrosion resistance, extending service life to 8–10 years.
Quality Assurance
All automotive CNC-turned parts undergo dimensional inspection using a coordinate measuring machine (CMM), material strength testing using a hardness tester, and surface roughness testing using a surface roughness tester before shipment, ensuring a final defect rate of ≤0.5%.
Why We Stand Out
Strong Customization Capabilities
We not only produce standard products, but also custom parts based on customer drawings, offering flexible adjustments in material, dimensions, tolerances, and surface treatment.
Sufficient Production Capacity
Our company produces 5,000 tons of forgings, 600 tons of copper extrusions, and 800 tons of die-cast parts annually, and CNC machines over 3 million parts annually, enabling us to promptly meet the demands of large-volume orders.
Quick Response
Our customer service team responds to inquiries within 24 hours, provides quotes or sample solutions within 2–3 days, and handles after-sales issues within 48 hours, minimizing customer wait times throughout the entire process.
FAQ
Q: What are the main applications for automotive CNC turned parts?
A: They are primarily used for connectors, bushings, and precision shafts in engines, transmissions, suspensions, and steering systems.
Q: Are your turned parts compatible with international standards?
A: We can process them according to DIN, ANSI, JIS, and other standards to ensure part compatibility.
Q: What is the processing efficiency?
A: The processing time for a single common shaft can be reduced to 2–3 minutes.
Q: Do we offer a sample-first policy?
A: We can confirm samples before mass production.
Q: What does the warranty cover?
A: Dimensional discrepancies, surface defects, and assembly issues are all covered by the warranty.
