Our CNC Precision Machining Services
Precision CNC Milling Services
Using top brands from China, we can guarantee CNC milled parts with tolerances within +/- 0.05mm while maintaining critical dimensions within +/- 0.005mm.
Our team also has extensive experience manufacturing precision parts for some of the world’s most demanding industries, including aerospace and medical.
The 5-axis CNC milling machine is equipped with an in-situ inspection system that allows us to monitor the actual dimensions of the part during the milling process. The computer is able to automatically adjust the program and parameters to ensure the part is manufactured correctly.
Precision CNC Turning Services
CNC turning employs a single-point cutting tool to produce precise cylindrical cuts on rotating materials. Unlike CNC milling, this automated process offers exceptional accuracy, high repeatability, and is specifically designed for creating circular or tubular components. During machining, the material is securely fastened and rotated at high speeds by the CNC lathe.
Our advanced CNC turning machines, operated by skilled technicians, ensure unparalleled precision in component manufacturing. These machines are optimized for short-run production of larger parts, particularly those exceeding 2.5” OD, whereas CNC milling is more suited for prototypes and parts with diameters under 2.5”.
Typical Applications of CNC Turning:
Functional prototypes、Spacers、Manifolds、Fittings、Shafts、Bushings
Precision Wire EDM Services
Wire Electrical Discharge Machining (EDM) is a cutting-edge, non-contact process that uses an electrically charged wire to cut conductive materials with exceptional precision and minimal material stress. This method is ideal for creating intricate geometries, tight tolerances, and smooth surface finishes, even in hard-to-machine materials like titanium, copper alloys, and hardened steel.
Our advanced wire EDM machines ensure consistent accuracy, with tolerances as tight as ±0.0001”. This process is highly versatile, making it suitable for manufacturing complex parts such as dies, molds, precision tooling, medical devices, aerospace components, and electronic connectors.
Precision Mirror EDM Services
Mirror Electrical Discharge Machining (EDM) is a specialized process that delivers ultra-smooth, reflective finishes with unmatched precision. This advanced technique uses a high-frequency electrical discharge to remove material, achieving surface finishes as fine as Ra 0.1μm while maintaining tight tolerances. It is ideal for creating parts with demanding aesthetic and functional requirements.
Our cutting-edge Mirror EDM technology enables the production of complex geometries in materials such as hardened steel, titanium, and copper alloys. This process is widely used in industries requiring flawless finishes, including high-performance tooling, optical components, medical devices, and aerospace applications.
Precision Grinding Services
Precision grinding is a meticulous machining process used to achieve exceptionally tight tolerances, superior surface finishes, and exacting dimensions. By utilizing abrasive materials and specialized grinding machines, this process ensures consistent quality, making it ideal for high-accuracy components and applications demanding smooth finishes or critical dimensional accuracy.
Our advanced grinding capabilities support a variety of materials, including metals, ceramics, and composites. Precision grinding is widely employed in manufacturing industries such as aerospace, medical, and automotive for parts like shafts, gears, spacers, and bearings, where flawless performance is paramount.

CNC Machining FAQs
When designing parts, some engineers suggest very tight tolerances, far more than are actually needed. That’s not an ideal approach. If +/-0.05mm works, opting for +/-0.01mm tolerance will increase the manufacturing cost many times. However, when you do need tolerances as tight as 0.01mm, then you can’t beat the accuracy and consistency offered by precision machining.
There’s a wide range of materials that can be used in precision machining – you can use aluminum brass, copper, steel, titanium, as well as rigid plastics like PPS, PEEK. Reach out to learn more about the types of materials that are available when using precision machining technology.
We use high-quality machines for precision CNC milling & turning, precision EDM, precision grinding, and a range of other tools in house, using AC to stabilize the workshop temperature. That, combined with the experience and qualifications of our engineers, as well as rigorous inspection of machines and processes, ensures consistent quality even in the most demanding scenarios.
