Nos capacités d'usinage CNC
We excel at machining parts with high precision tolerances and complex geometries. Leveraging advanced technology, our precision CNC machining services can transform your designs into high-quality components.
CNC Milling Service
Our factory houses advanced 5-axis CNC milling machines, enabling us to perform precision milling on plastic and metal materials with intricate geometric shapes. For projects requiring high efficiency and low cost, we also provide low-cost machining services using high-precision three-axis and four-axis milling centers.
Service de tournage CNC
CNC turning is a more efficient process for manufacturing high-quality cylindrical parts (such as worm gear shafts) from plastic and metal bars or tubes. Our lathes utilize powered tools to achieve simultaneous milling and turning, reducing delivery time and ensuring part accuracy.
Service d'électroérosion et de découpe par fil
EDM and wire cutting are indispensable processes in CNC machining, enabling precision machining that is impossible with traditional milling. Using copper, graphite, or molybdenum wires, we can precisely cut complex shapes such as sharp angles and chamfers with extremely high EDM accuracy, and remove excess material from hardened workpieces.
Service de rectification CNC
If you require parts with ultra-flat surfaces or circular parts with tolerances of ±0.005 mm for both outer and inner diameters, our CNC grinding service is ideal.
Service d'usinage suisse
Swiss machining offers an extremely efficient way to manufacture slender, complex parts without the risk of deformation. The synchronized movement of the powered tool and the workpiece allows for cutting of the material within the workpiece fixture. Compared to conventional CNC lathes, it provides greater stability and prevents part deformation.
Service de fraisage CNC
In addition to standard precision milling services for engineering plastics and metals, we also offer professional CNC engraving services. This service is ideal for CNC engraving. It’s perfect for prototypes and parts made from soft materials such as EPS foam, wood, and EVA.
Qu'est-ce que l'usinage CNC ?
CNC machining, or Computer Numerical Control machining, is a high-precision subtractive manufacturing process. It uses high-speed cutting tools to automatically machine high-precision parts from metal or plastic materials.
Common CNC machines include 3-axis, 4-axis, and 5-axis milling machines (where the workpiece can remain stationary while the tool moves), CNC lathes (where the tool remains stationary while the workpiece rotates and moves), and router machines (where the tool and workpiece can move simultaneously).
Experienced technicians program CNC machines using CAD models, enabling the creation of precise and repeatable toolpaths.
One of the greatest advantages of precision CNC machining is its compatibility with a wide variety of materials. The process works with virtually any metal or hard plastic, providing durable solutions for aerospace, medical, and automotive applications.

3. Inspection en cours de fabrication: Throughout the CNC machining production phase, our quality control team conducts regular measurements and interval checks to immediately identify and resolve any deviations, thereby ensuring zero-defect production.
4. Inspection finale: After machining, we conduct rigorous inspections. We verify specifications such as critical dimensions, surface roughness, and appearance finish. This ensures that each part fully meets your expectations and standards before shipment.
Tolérances d'usinage CNC
Our general linear tolerance for machined metal parts is lS0 2768 (fine) and lS0 2768 (medium) for plastic parts.
Normally, we can meet the machining accuracy of +0.127mm. If tighter tolerances are required, a 2D drawing with annotation information will be necessary. Our engineering team will communicate the critical dimensional tolerances to you and provide the highest possible machining accuracy.
