Zhonghanda FAQs
Find quick answers about CNC machining quotes, materials, tolerances, surface finishing, quality inspection and delivery for custom parts.
Simply upload your CAD file (supported formats: STEP, IGES, DWG, etc.). Our technical team will complete the design review and provide a detailed quote within 24 hours. The quote includes machining cost, material cost, surface treatment, and estimated lead time.
No minimum order quantity. Whether it is a single prototype or high-volume production, we treat every project with equal attention. We specialize in low-volume, high-mix precision machining, while also having the capacity and efficiency for mass production.
We machine a wide range of materials, including aluminum, stainless steel, titanium, copper, engineering plastics (PEEK, POM, etc.), and high-temperature alloys such as Inconel. Standard machining tolerance can reach +/-0.005mm, with high-precision requirements achievable at +/-0.002mm.
We have an independent quality inspection team that checks every critical step in the process. From raw material incoming to finished parts shipping, full traceability is maintained. Inspection equipment includes CMM, optical measurement instruments, surface roughness testers, and more.
Your project is managed by our production team to ensure scheduling and progress control. We use a dedicated team model to avoid delays caused by overlapping projects. If a delay occurs due to our side, we will communicate in advance and provide appropriate solutions.
We provide comprehensive quality assurance. If parts do not meet your drawing requirements due to our error, we will arrange for remanufacturing or issue a refund after confirmation. Your satisfaction is the foundation of our long-term partnership.
