The series of machines features an integral high-rigidity bed structure with high levels of standardization and modularity. The standard configuration of the machine adopts the GSK external cylindrical grinding machine numerical control system, known for its stable performance, user-friendly operation, easy maintenance, and high precision control. It can achieve programmed plunge grinding, measurement control grinding (requires optional measuring device), automatic wheel dressing, compensation, and other functions.
- The grinding wheel spindle adopts a large-diameter hydrostatic spindle, ensuring high rotational accuracy and strong rigidity. It can be equipped with a large-diameter ultra-wide grinding wheel for contour plunge grinding. The grinding wheel spindle motor adopts an AC variable frequency speed control device, enabling segmented constant linear speed grinding.
- Both the grinding wheel carriage and the worktable are driven by AC servo motors through ball screws, with the grinding wheel carriage feed guide rail adopting imported roller linear guides to ensure feed rigidity and accuracy.
- The wheel head is driven by a servo motor, allowing for step-less speed control and precise stopping at any position.
- Optional configurations include imported or domestic active measurement devices for online measurement of grinding processes. The tailstock adopts a hydraulic telescopic sleeve structure and can also be customized as a tailstock with linear guide movement.
- Control System: Standard configuration includes the GSK grinding machine system. Optional configurations are available with Siemens or FANUC systems.
