Description

Product overview
The G5 Series is a CNC cylindrical grinder designed for high-precision grinding of large workpieces. Improved load capacity and a high-rigidity structure provide stable machining accuracy. Automated machining-condition setting, automatic diameter measurement and steady-rest adjustment reduce variability from operator skill and lower operator workload. STAT BEARING®, precision hand-scraped sliding surfaces, and thermal and vibration countermeasures sustain high accuracy for large rolls and shafts over long periods.

Benefits

Automation of condition setting and measurement/adjustment reduces the burden of determining machining parameters and minimizes skill-based variability.
Automatic diameter measurement and steady-rest adjustment streamline operations and help maintain consistent machining quality.
Precision scraping of major sliding surfaces, thermal-displacement countermeasures and a low-vibration, high-rigidity bed maintain accuracy over extended periods.
Supports larger and heavier workpieces with center load capacity up to 1,500 kg (options available), high-power wheel spindle and larger wheel diameters.

Main features

Automatic diameter measurement and steady-rest adjustment
Automatic machining-condition setting via 'Easy Operation' mode
Steer-by-wire handle and slide-type control panel for operation support
Workpiece capacity up to 1,500 kg between centers (varies by model/spec)
Wheel spindle motor: 11 kW (standard) [15 kW optional]
Tailstock taper adjustment function
High-rigidity, low-vibration bed and precision hand-scraped surfaces
STAT BEARING® (fluid bearing) for reduced wear and high rigidity/damping
Full center-cover configuration, sleep-in/wake-up modes, and energy-visibility functions for safety and environmental performance
