Grinding process descriptions
On the JUNICOR platform 3, precise diameter and face grinding is achieved, including angular plunge-cut grinding for turbocharger shafts and other high-precision shaft components.

Special solutions

• Wheelhead: Multiple wheelhead and table configurations are available, from standard assemblies to custom solutions tailored to part geometry and production requirements.
• Wheelhead (variant): Variants with up to three grinding spindles provide increased process flexibility and multi-operation capability.

Equipment features (examples)

• Machine bed in mineral cast for damping, torsional rigidity and thermal stability
• Patented 3-point mounting interface for fast mounting and centering of grinding wheels, dressing tools and workholding devices
• Tailstock and workhead adjustment via chain wheel, hydraulic cylinder or CNC axis with rack-and-pinion drive; optional air-lift function
• Longitudinal positioning using a touch probe for automatic compensation of raw-part length variations
• Optional self-centering three-point steadies with tracking hydraulic jaws for stable support

Workpieces

• Turbocharger shafts
• Turbine shafts
