Core Manufacturing Process

Step Variable Diameter Integral Spinning. Uses "Shared Tooling with Parameter Fine-Tuning" for flexible manufacturing, solving rapid changeover for 19 diameters (φ585 to φ342). Overcomes high springback and cracking issues in high-strength steel.

19-Step Variable Diameter Steel Cone – High Precision Assembly Fit

Q355D Steel
Hole position tolerance: ±0.05mm
Sandblasted surface

Ensures perfect multi-layer assembly without misalignment.

Precision Control

EQS (Equally Spaced) Hole Precision Machining via CNC rotary table indexing. Hole position tolerance controlled within ±0.05mm. Step dimensions are strictly controlled to ensure no misalignment in 19-layer stacking.

Surface Treatment

Full coverage Sandblasting on internal and external surfaces. Uniform Ra 6.3 roughness, free of oxide scale, rust, or scratches. Internal cavity is clean and residue-free.

Material Adaptability

Specialized in Q355D steel. Strictly controls material negative tolerance and mechanical properties, ensuring excellent toughness even at -20℃ low-temperature environments.
