We can machine a wide range of materials via CNC milling, including various metals and plastics. Metals cover aluminum (such as 6061, 7075), stainless steel (like 304, 316), carbon steel, brass, copper, titanium, and more. Plastics include ABS, PC, POM, PP, PE, nylon, PEEK, and other engineering plastics. We select suitable cutting tools and process parameters according to the material properties to ensure machining quality.

The maximum part size we can process through CNC milling depends on the model of our CNC milling machines. For soft metals and plastics, the maximum part size can reach 2000×1500×200mm or 1500×800×500mm; for hard metals, it can reach 1200×800×500mm. If you have parts with larger dimensions, please contact our team in advance, and we will provide a customized machining solution based on your specific needs.

The turnaround time for CNC milling orders varies depending on the complexity of the parts, order quantity, and material selection. For simple prototype parts or small-batch orders (less than 50 pieces), we can usually complete the machining and deliver within 7-10 days. For complex parts or large-batch production orders, the delivery time may be 2-4 weeks. After receiving your order details, we will provide you with an accurate delivery schedule.

Absolutely. We are equipped with advanced 3-axis and 5-axis CNC milling centers, which have high positioning accuracy and repeatability. Our standard CNC milling tolerance follows ISO 2768 – m for metals and ISO 2768 – c for plastics, with a typical tolerance of ±0.025mm (±0.001 inch) for linear dimensions. For parts that require tighter tolerances (such as ±0.005mm), we can achieve them by optimizing the machining process, using high-precision cutting tools, and conducting strict quality inspections. Just let us know your specific tolerance requirements when placing the order.

Yes, we provide a variety of surface finishing services to enhance the performance and appearance of CNC milled parts. Common surface treatments include anodizing (natural, black, colored), electroplating (zinc plating, chrome plating, nickel plating), sandblasting (matte, fine sand, coarse sand), polishing (mirror polishing, wire-drawing polishing), passivation (for stainless steel), painting (customizable colors), silk screen printing, and laser engraving. You can choose the appropriate surface treatment method according to the application scenario and appearance requirements of the parts.

Getting a quote for your CNC milling project is simple. You only need to send us the detailed information of the project, including 2D/3D drawings of the parts (in formats such as CAD, STEP, IGES), material requirements, tolerance specifications, order quantity, surface treatment needs, and delivery time requirements. You can submit this information to us via email, our official website’s contact form, or by calling our sales team. We will review your project details within 24 hours and provide you with a detailed and accurate quote.

Yes. Our team has professional engineers with rich experience in CNC machining. They are familiar with the machining characteristics and process limitations of CNC milling. If you are in the early stage of part design, we can provide design suggestions to optimize the part structure, reduce machining difficulty, and lower production costs (such as optimizing the size of holes, avoiding overhangs that are difficult to machine, and selecting suitable material thickness). We can also check and modify your existing drawings to ensure they are compatible with our CNC milling processes.

We attach great importance to the quality of CNC milled parts and have established a strict quality control system throughout the machining process. First, we inspect the raw materials to ensure they meet the specified material standards. During the machining process, our operators conduct real-time monitoring and sampling inspections using precision measuring tools (such as calipers, micrometers, height gauges). After the parts are machined, we use advanced measuring equipment like coordinate measuring machines (CMM) to conduct a comprehensive inspection of the dimensions, tolerances, and surface quality of the parts. Only parts that pass all inspections will be delivered to customers. We also keep detailed quality inspection records for each order for traceability.

Yes, we have the capability to handle both prototype and production – volume CNC milling orders. For prototype orders, we focus on fast turnaround and high precision to help you verify the design of the parts quickly. For production – volume orders (from hundreds to thousands of pieces), we optimize the production process, use automated equipment to improve production efficiency, and ensure the consistency and stability of product quality. Whether it is a small prototype or a large – batch production, we can provide reliable machining services to meet your different stage needs.

Our CNC milling services cover a wide range of industries, including medical devices (such as surgical instruments, medical device components), aerospace (aerospace structural parts, engine components), automotive (automotive parts, mold components), defense (military equipment parts), electronics (electronic device housings, connector parts), hardware startups (prototype development, small – batch production), industrial automation (automation equipment parts, mechanical components), machinery (mechanical parts, transmission components), marine (marine equipment parts), and robotics (robot structural parts, joint components). We have in – depth understanding of the specific requirements of different industries and can provide industry – specific machining solutions.
