CNC spinning machine specifications should be read as production limits, not as isolated numbers. A model with the right diameter but insufficient stroke, rigidity, tooling access, or material capacity may not be the right machine for the job. Buyers should connect every specification to the part drawing and the expected production rhythm.
1. Maximum blank diameter
Maximum blank diameter is usually the first number buyers compare. It tells you the largest starting disc or workpiece the machine can handle. However, the final part profile also matters. A shallow cover and a deep cone can have similar blank diameters but need different roller travel and forming strategy.
2. Lateral stroke and forming depth
Stroke defines the available movement for the tool path. Deeper parts such as cones, horn shapes, parabolic reflectors, and industrial shells need enough travel and clearance. If the stroke is too limited, the machine may not complete the profile safely or consistently.
3. Material thickness range
Catalog thickness ranges normally differ by material. Iron, brass, aluminum, and stainless steel have different forming behavior. Stainless steel usually requires more forming force and careful process control. Aluminum may allow thicker blanks but can still show surface marks if tooling and lubrication are not correct.
4. Spindle speed, rigidity, and tailstock force
Spindle speed must be matched with material, diameter, tool path, and safety requirements. Rigidity helps reduce vibration and improves repeatability. Tailstock or clamping force is important for stable forming, especially when the part is large, deep, or thick.
5. Single-side, double-side, and turret configurations
A single-side CNC spinning machine is practical for many lamp, cookware, cover, and shell parts. Double-side or turret configurations may be considered when a part family needs faster cycles, more complex passes, or more tool stations. The right configuration depends on product mix rather than a simple “bigger is better” rule.
6. Model range reference
| Model | Max blank diameter | Stroke | Typical direction |
|---|---|---|---|
| X-400 Simple | 420 mm | 450 mm | Reflectors, lamp shades, small cookware |
| X-600 Standard | 620 mm | 500 mm | Mid-size lighting, cookware, covers |
| X-800 Single | 810 mm | 600 mm | Fan parts, large reflectors, industrial shells |
| X-1200 Single | 1240 mm | 910 mm | Extra-large cones, domes, heavy shells |
Specification checklist before supplier review
- Blank diameter, final diameter, forming depth, edge shape, and tolerance.
- Material grade, thickness, surface finish, and whether polishing or coating follows.
- Part family: cylinder, cone, parabolic reflector, horn, bullet shape, vase, gourd, or sphere.
- Monthly output, shift plan, operator skill level, and production changeover needs.
- Tooling, run-off sample, training, packing, and export documentation requirements.
The best model recommendation comes from combining the catalog range with real part data. If the part is close to the capacity limit, send drawings and samples before choosing the machine only by table numbers.
Compare CNC spinning machine models or send your part drawing for model recommendation.
Specification data buyers should send
Machine selection becomes faster when the inquiry includes both product data and production goals. The same diameter can need a different model if the depth, material, forming route, or output target changes.
- Blank diameter, finished diameter, forming depth, trimming allowance, and edge detail.
- Material grade, thickness range, surface finish requirement, and follow-up polishing or coating.
- Daily or monthly quantity, shift plan, operator experience, and available floor space.
- Whether the project needs tooling design, first-article verification, installation, or remote training.
