PFG-2460AHR Hydraulic Surface Grinder

 
Machine may be shown with optional accessories.

Column type hydraulic surface grinder with full support on complete table travel to avoid table overhang. 

FEATURES: 
  • Vertical travel driven by AC servo motor
  • Vertical travel operated by MPG function handwheel with 3 graduation selections
  • One piece base design to provide greater rigidity and free twist deformation to ensure superior surface finish and higher accuracy
  • Column, base, and table adopt double wall construction casting to ensure greater rigidity, accuracy, and stability during heavy grinding.  And through internal stress elimination assures rigidity, stability, and accuracy
  • High precision and heavy pre-compression ballscrews on vertical and cross feeds to provide powerful and precise grinding force
  • Hydraulic driven longitudinal table movement
  • Automatic cross feed powered by AC motor transmitting through MCU.  The travel distance set by cam and limit switch installed on right side of machine base.  The feed volume can be adjusted by panel switch
  • 2 single-acting hydraulic cylinders to maximize stable table movement by preventing table floating
  • Optional automatic down feed with elevating micro-feed and intuitive control panel to add more convenience to grinding operations
