As your strategic Original Equipment Manufacturing (OEM) partner, HS Metal Spinning is dedicated to Precision Metal Spinning. This advanced cold-working process utilizes multi-axis CNC lathes and hardened mandrels to incrementally shape a rotating metal blank into a seamless, hollow component. Precision is achieved through the digital control of forming pressure, tool path velocity, and material flow, ensuring every part adheres to strict geometric specifications. We expertly form materials including Stainless Steel, Aluminum, Titanium, and specialty alloys, guaranteeing dimensional accuracy, uniform wall thickness, and superior structural strength for demanding applications in aerospace, high-vacuum, and optics.
Our focus on precision spinning provides critical engineering and performance benefits over traditional fabrication and general stamping:
Our CNC equipment ensures perfect concentricity and rotational balance. This is vital for components that rotate (like fan cowlings) or those that require precise mating interfaces (like high-vacuum chambers), preventing dynamic imbalance and sealing failures.
Unlike deep drawing where material thinning is common and unpredictable, our precision spinning process allows for careful management of material flow, ensuring the component maintains uniform wall thickness from the crown to the flange, a non-negotiable requirement for pressure vessels.
On key features such as diameter, straight flange length, and overall height, we routinely hold tolerances down to $\pm 0.2 \text{ mm}$. For features requiring even tighter control, we integrate secondary high-precision CNC machining.
The controlled, high-pressure cold-forming inherent in precision spinning increases the material's yield strength and hardness, resulting in a monolithic component with superior strength-to-weight ratio and excellent structural stability.
Achieving repeatable precision in metal spinning requires a highly controlled, fully digitalized workflow:
We translate your component's 3D CAD model into optimized CAM tool paths, calculating material flow and pressure to achieve the final shape while ensuring the material's elastic limits are respected.
A hardened, CNC-machined mandrel—the internal template of the final part—is mounted on the lathe, ensuring zero runout and providing the rigid foundation for precise forming.
The metal blank is spun. Multi-axis, digital controls guide the forming roller across the blank, applying incremental pressure with absolute repeatability to achieve the specified geometry and wall thickness.
While the component is still mounted, final trimming of the excess edge material and the forming of specialized edges (e.g., beading or flaring) are completed with high precision.
The finished component is inspected using Coordinate Measuring Machines (CMMs) to verify every critical dimension and geometric tolerance, with full MTRs provided for material traceability.
We verify the precision using CMMs and laser scanners, which compare the physical geometry of the spun part against the original 3D CAD model to ensure dimensional accuracy.
For deep-drawn, rotationally symmetrical parts, precision spinning is significantly more cost-effective due to much lower tooling costs, faster prototyping, and flexible production volumes.
Yes. Our high-tonnage CNC lathes are designed to handle difficult-to-form, high-strength metals like Titanium, Inconel, and various stainless steel grades, ensuring the cold-working is performed effectively.
