Cold Processing-CNC Machining Services

Qilu offers CNC machining services for the manufacture of precision metal parts. Our high-speed CNC machines are equipped with the latest software programming and are operated by highly skilled CNC technicians. Fushun can produce complex pieces directly from 3D Computer-Aided Design (CAD) data with detail-oriented precision using 3-axis, 4-axis and 5-axis CNC machines, including vertical milling machines, horizontal milling machines and lathes.

Qilu employs CNC machinery that performs complex operations such as turning, milling, drilling, tapping and deep-hole boring. Qilu supports all processes in precision machining with an effective quality control program. We use our engineering expertise, experience, state-of-the-art equipment and in-depth knowledge to serve a variety of different industries, including medical, aerospace, defense, automotive and consumer goods.

Qilu rapid prototypes—both cosmetic and functional—to low-volume production parts, Fushun CNC machining team is part of its secure facility and follows processes to protect a company’s IP (e.g., NIST 800-53 Compliant). Customers can choose from a wide variety of metal material options or can make special material requests. The team offers a tolerance accuracy range from +/-0.001″ to 0.005″ and can support even faster lead-times for on-demand reorders.
