G7020S Movable Column Surface Grinding Machine: spindle speed 950 rpm, worktable area 2000×700 mm, table movement 2230 mm. Request a quote.
The G7020S is a movable-column surface grinding machine for large, heavy workpieces. The column travels front to back over the table, so the table only moves longitudinally and can carry heavy parts with high accuracy.
Spindle speed 950 rpm, worktable area 2000×700 mm, table movement 2230 mm, grinding wheel Ø355×40×127 mm and maximum table load 1500 kg.
Because the heavy workpiece does not move crosswise, accuracy stays high across a large working area. Servo-driven vertical feed and automatic feed cycles help to grind large plates and die sets efficiently.
Wheel size, chuck, coolant filtration and feed system can be matched to your parts. Send the largest workpiece size, weight and required flatness for a proposal.
Spindle speed 950 rpm, worktable area 2000×700 mm, table movement 2230 mm, grinding wheel Ø355×40×127 mm and maximum table load 1500 kg. The full data is in the specification table on this page.
