Our CNC Machining Capabilities
We are an original equipment manufacturer (OEM) at the Mulan Group, where we have a 5,000-square-meter facility equipped with state-of-the-art equipment for a wide range of precision CNC machining services. This supports our ability to manufacture all high-quality CNC precision-machined parts for our customer base. Our CNC machining capabilities encompass turning, milling, mill-turn turning, and five-axis CNC machining. For shafts and disc-shaped parts, precision turning ensures excellent roundness and concentricity control. For housings and structural components, CNC milling provides precise surface finishes, cavity machining, grooving, and keyway machining. When handling complex curved surfaces or polyhedral features, five-axis CNC machining enables single-setup, significantly improving accuracy and consistency while reducing fixture errors.
We support a wide range of materials, including aluminum alloys (6061, 6063, 7075), stainless steel (304, 316, 303), carbon steel, brass, and engineering plastics such as POM and PEEK. In mass production, typical dimensional tolerances can be controlled within ±0.01–0.02 mm, and critical locations can achieve ±0.005 mm through precision calibration and tool compensation. Surface finishes can reach Ra0.8–Ra3.2, depending on the machining strategy and post-processing requirements.
Our machining strategies are based on product design characteristics: turning for axisymmetric parts; milling for planar and structural surfaces; mill-turn machining to improve the machining efficiency of mixed geometries; and five-axis machining for high-precision or complex surface features. All machining processes employ fixture optimization, toolpath simulation, process inspection, and final quality verification to ensure dimensional stability, batch repeatability, and reliable functional performance. This enables us to meet the high-precision machining needs of applications in automotive, industrial equipment, instrumentation, aerospace, and consumer electronics.
When you choose us to meet your CNC machining needs, you will receive finished products that exceed your expectations in terms of quality, precision, and accuracy. With extensive turning capabilities, we have the experience and knowledge to handle any project and meet precise specifications.
CNC Machining Industry Applications
Because we have a casting business, CNC machining is a crucial component of our machining production line. Our CNC machining services are widely used in the automotive, industrial machinery, aerospace, medical device, and consumer electronics industries. In the automotive industry, we supply precision housings, brackets, and connector assemblies that require consistent dimensional repeatability, typically with tolerances controlled within ±0.01–0.03 mm to ensure mechanical fit and vibration resistance. In industrial equipment and automation systems, we machine shafts, disks, and structural frames that demand high concentricity and perpendicularity; tolerance chains and positioning accuracy directly impact assembly stability and transmission efficiency.
In aerospace and drone applications, lightweight aluminum and titanium alloy parts require stringent weight control, consistent surface integrity, and high precision for complex geometries. Our five-axis machining ensures multi-surface machining in a single setup, keeping critical features within ±0.005–0.01 mm. Medical device components require excellent surface finishes, burr-free edges, and biocompatible materials such as 316 stainless steel and titanium alloys; we maintain a surface roughness of Ra0.8–Ra1.6 by controlling cutting and polishing processes. For consumer electronics, we offer thin-walled housings and surface treatment processes, focusing on precise contour consistency, aesthetically pleasing surface finishes, and uniform anodizing performance.
By customizing machining strategies, fixtures, cutting parameters, and inspection standards for specific industries, we ensure reliable quality, consistent mass production performance, and reliable delivery across diverse application scenarios.
Some of the industries we serve include:
- Aerospace: landing gear parts, engine components, panels
Consumer - electronics: housings, chassis, fixtures
- Health care: surgical instruments, electronic housings
- Machinery and Equipment:Pumps, valves, and gears
- Energy: brackets, panels, frames

Comparison of key dimensions of processing technology：
| Comparison categories | CNC & Turning & Milling & Drilling | WEDM |
| Applicable Materials | Ordinary metals (steel, aluminum, copper) Some non-metals (plastics, wood) Not suitable for ultra-hard materials (need to be processed after annealing). | Conductive materials (such as hardened steel, cemented carbide, titanium alloy, graphite) High hardness materials can be processed directly without annealing. |
| Processing accuracy | Not suitable for superhard materials (need to be processed after annealing). General accuracy: IT7~IT8 After fine grinding, it can reach IT6, and the surface roughness Ra 0.1~0.4 μm. | Accuracy can reach IT5~IT6 (slow wire cutting can reach ±0.002 mm) Surface roughness Ra 0.1~3.2 μm (slow wire cutting is better). |
| Processing complexity | Limited by tool shape and machine tool movement Difficult to process complex cavities, sharp corners, and microstructures. | Any plane contour can be processed (such as special-shaped holes, sharp corners, and micro grooves) No physical contact, suitable for complex geometric shapes. |
| Application Scenario | Mass production (automobiles, general machinery) Regular geometry parts (shafts, gears, planes, holes) | High-precision, small batch or single-piece processing (molds, aerospace, medical devices) Hardened parts, carbide cutting, complex contour processing (such as precision mold inserts, fine electrodes). |
