Precision Sheet Metal Machining & Rolling | One‑Stop CNC + Roll Forming

For industrial components that require both curved/cylindrical shapes and precision features (holes, threads, slots), a fragmented supply chain creates tolerance stack‑ups and delays. As a precision sheet metal manufacturer with 12 years of experience, we integrate sheet metal rolling (forming cylinders, cones, arcs) and sheet metal machining (CNC milling, drilling, turning) into one seamless workflow. This end‑to‑end solution delivers consistent quality, reduced lead time, and lower total cost – whether you need a single prototype or high‑volume production.

⚙️ Sheet Metal Machining: Ultra‑Precision Finishing

Our CNC machining department is equipped with state‑of‑the‑art mills, lathes, and drilling centers, achieving tolerances as tight as ±0.005mm. We handle materials from stainless steel (304, 316) and aluminum (6061, 5052) to carbon steel and exotic alloys (titanium, Inconel). Techniques include milling, drilling, tapping, turning, and contouring, all programmed via advanced CAD/CAM for perfect repeatability. Every part is verified with CMM and visual inspection.

🌀 Sheet Metal Rolling: Precision Curved & Cylindrical Forming

Our rolling shop operates CNC 3‑roll and 4‑roll machines that bend flat sheet metal into consistent cylinders, cones, arcs, and custom curved shapes without compromising structural integrity. Material thickness from 0.5mm to 12mm, width up to 2000mm, and cylinder diameters from 50mm to 2000mm. 4‑roll technology allows pre‑bending both edges, minimizing flat spots and ensuring leak‑proof seams for tanks and pipes.

• Rolling types: cylindrical, conical, curved, segmented arcs
• Thickness range: 0.5–12mm (mild steel, stainless, aluminum)
• Max width: 2000mm | Diameter range: Φ50–2000mm
• Integrated with machining for post‑roll drilling/tapping

🔗 Why integrate rolling & machining? Real‑world synergy

Many rolled components require precision machining to become functional: a cylindrical tank needs inlet/outlet holes, threaded fittings, and finished edges. When rolling and machining are done by separate suppliers, misalignment of holes relative to the weld seam or inconsistent cylinder geometry leads to costly rework. Our integrated approach guarantees that every rolled part is fixtured and machined using the same datum, ensuring perfect alignment.
