Yes, Maijin Metal provides comprehensive First Article Inspection (FAI) reports and fully supports the Production Part Approval Process (PPAP) for all custom CNC parts. These quality assurance documents are essential for verifying that our manufacturing process consistently meets your exact design specifications.
This level of documentation is particularly critical for industries with strict regulatory requirements, such as automotive, aerospace, and medical device manufacturing. In these sectors, demonstrating part consistency and process reliability is mandatory before moving into mass production.
When submitting your Request for Quote (RFQ), please specify your required QA documentation and compliance levels—such as PPAP Level 3 or Level 4. Our engineering team will review your requirements and seamlessly incorporate the necessary preparation and reporting costs into your initial quote. This ensures complete pricing transparency with no hidden fees, while guaranteeing your parts satisfy the highest industry quality standards.
Yes, Maijin Metal can help you engineer your part. We provide professional Design for Manufacturability (DFM) guidance to optimize your design for CNC machining. Our experienced engineers review your drawings and suggest practical improvements that reduce production costs, shorten lead times, and enhance overall part quality — all while fully preserving the original functionality and performance.
As a trusted custom CNC machining supplier, we specialize in helping clients across the automotive, aerospace, medical, and electronics industries refine complex components. Common DFM recommendations include adjusting tolerances, simplifying geometries, selecting more cost-effective materials, and optimizing for our CNC milling and turning capabilities.
This collaborative approach minimizes manufacturing risks, eliminates unnecessary expenses, and ensures your parts are easier to produce at scale. Whether you are in the prototype stage or preparing for mass production, early DFM feedback from our team delivers significant value.

The answer depends on several factors including part complexity, material, geometry, and required tolerances. At Maijin Metal, we can generally machine parts with minor outside diameters (ODs) as small as 2mm (0.080”) and major ODs up to 200mm (8”) . We are capable of producing both micro-precision miniature components and larger, more complex parts while maintaining tight tolerances.
As a professional custom CNC machining supplier, Maijin Metal serves a wide range of industries including automotive, aerospace, medical devices, and electronics. We handle everything from rapid prototypes to high-volume production runs.
Our experienced team offers free DFM feedback to optimize your designs for cost, quality, and efficiency. We recommend reaching out early in the design phase. Explore our full CNC machining capabilities and send us your drawings today for a detailed manufacturability review and quote.
A lathe is a basic machine that rotates bar stock to create turned parts, but it typically lacks milling capability. A screw machine is an automated lathe designed for high-volume production of simpler turned parts like screws and fasteners. A turning center is a more advanced CNC lathe that combines turning with live tooling for milling, allowing complex parts in fewer setups. A CNC lathe uses computer numerical control for precise, programmable operation, offering superior accuracy and repeatability.
At Maijin Metal, a professional custom CNC machining supplier, we utilize advanced turning centers and Swiss-type CNC lathes to produce high-precision components with tight tolerances for automotive, aerospace, medical, and electronics industries. These machines enable us to handle everything from prototypes to mass production efficiently while maintaining exceptional quality.
