For added assurance, we also offer inspection options, hardware traceability, material certifications, and Certificates of Conformance (CoCs).
CNC machining (Computer Numerical Control machining) is a highly precise and automated manufacturing process that uses computer-controlled cutting tools to shape designs from metal or plastic stock. Depending on the complexity of the project, CNC machines can range from 3-axis and 4-axis milling machines to advanced 5-axis systems, lathes, and routers.
The way a part is machined can vary, sometimes the tool moves while the workpiece stays fixed, sometimes the workpiece rotates while the tool remains in place, and in many cases, both tool and workpiece move together to achieve complex geometries.
Using CAD (computer-aided design) models, skilled machinists program the machine to follow exact tool paths, ensuring that each part is cut with exceptional precision and repeatability.
TOUWEI is your trusted partner for high-quality prototypes and end-use machined parts, from simple to highly complex designs. With 700+ advanced CNC machines, we provide milling, turning, routing, EDM machining, drilling, and precision grinding. Our ISO 9001 certification and skilled expertise ensure accuracy and consistency in every project.
With over 200 dedicated milling centers, including 3-axis, 4-axis, and advanced 5-axis CNC mills, TOUWEI delivers tight-tolerance components and intricate geometries in both plastics and metals. We serve multiple industries while also specializing in precision mold making.
Our CNC lathes, turning centers, and mill-turn machines enable us to produce precise cylindrical parts, along with components from square or hexagonal raw materials. TOUWEI provides both prototype and production parts with rapid lead times, often delivered within just a few days.
Our CNC machines operate with precision tolerances that meet industry standards, ensuring that every part is consistently accurate and fits perfectly with other components.
