Short description
Internal-ring grinding machine for grinding external diameters of CV joint ball hubs and similar workpieces; model Meccanodora 1231/CNC with integrated handling and automation.

Product overview
The Meccanodora 1231/CNC is engineered for high-precision grinding of external diameters on ball hubs used in CV joints or comparable components. The machine combines a compact, ergonomic layout with CNC control and an integrated loader to ensure rapid, repeatable loading/unloading and stable production in series manufacturing environments.

Industries

• Automotive OEMs and suppliers — production of drive-shaft and joint components
• Truck and commercial vehicle manufacturers and suppliers
• E‑Mobility — series production of high-precision drive components

Advantages

• Grinding setup: uses conventional 500 mm diameter grinding wheels with circumferential speed up to 63 m/s and a 34° workpiece angle to optimize grinding beneath interrupted cuts.
• Precision clamping and centering: workpieces clamped in the bore and positioned on the end face; centring without axial stress via magnetically driven carbide shoes or via collet chuck systems.
• Precision dressing: diamond or profile-roll dressing for accurate wheel profiling and long-term process stability.
• Automation and ergonomics: integrated loader/handling system for automatic loading/unloading and short changeover times; ergonomic machine layout for user-friendly operation.
• Enclosure and maintenance: full enclosure option and low-maintenance design suitable for continuous series production.

Applications
Suitable for highly precise and cost-effective grinding of external diameters on ball hubs (joint hubs) in CV joints and for similar hub-shaped components. Ideal for automated series production with minimal setup time and consistent part quality.
