Heavy-duty CNC cylindrical roll grinding machine specifically engineered for precision grinding of steel mill rolls, paper industry rollers, heavy shafting, and cylindrical components. Features automatic crown/convexity curve grinding, high-rigidity bed architecture, and sub-micron dimensional control with Fanuc, Siemens, Mitsubishi, or FAGOR CNC controls.
Model Variants
We can customise all Specification as client needs
Automatic Roll Curve & Crown Grinding :
Equipped with dedicated roll curve interpolation software capable of generating sine curves, parabolic crowns, concavity, and custom taper profiles with precise wheelhead tracking.
High-Rigidity Heavy-Bed Construction :
Stress-relieved, heavy-ribbed cast iron machine bed with hydrostatic / heavy linear roller guideways ensuring zero-vibration stability under heavy workpiece loads up to 10,000 kg.
High-Precision Workhead & Tailstock Drives :
Direct-drive AC servo workhead with variable speed control and hydraulic/pneumatic tailstock sleeve clamping to maintain perfect concentricity and cylindrical geometry.
Supported CNC Controllers & In-Process Gauging :
Integrated with industry-standard Fanuc, Siemens, Mitsubishi, or FAGOR CNC systems with optional automatic in-process diameter measuring probes and wheel dressing units.
Detailed performance metrics, capacity dimensions, and drive parameters across models.
