Typical Applications

Straight cylindrical grinding of shafts and rolls in plant maintenance and heavy engineering workshops.
Grinding of long shafts, rolls, and turbine rotors in steel and power plants.
Precision finishing of pump shafts and motor shafts in cement plants.
Marine applications including grinding of propeller shafts and rollers in shipyards.
These machines are intended for straight external cylindrical grinding, not taper or angular grinding.

• Machine configuration is governed by job weight and support method to maintain stability while grinding heavy rotating masses.
• High-mass cast iron bed and structural components with V-and-flat guideways provide long-term geometric stability.
• Electromechanical table and work head drives with VFD control enable smooth, infinitely variable feed and speed control.
• Designed for wet grinding operations, with wheel head, coolant, and job support arrangements matched to straight grinding duty.
• Manual spring-loaded tailstock, with job support through centres, chucks, and steadies based on application.
• These machines are typically deployed in both production and reconditioning environments, where rigidity and repeatability matter for a smooth surface finish.

Geometric Accuracy Standards: As per IS: 2368.

Heavy duty cylindrical grinders are designed around job weight, stiffness, and job support mechanism, rather than centre distance alone.
Machines can be customised to user requirements and application-specific solutions, configured for centre-to-centre grinding with fixed or travelling steadies as required.
Angular grinding applications require fundamentally different machine architecture.
