Features of the Single-Axis Programmable Horizontal Reciprocating Table Bearing Surface Grinder:
● The worktable reciprocates on the bed, while the grinding head moves horizontally on the carriage. The carriage, along with the grinding head, moves vertically on the column.
● The worktable's reciprocating motion is hydraulically driven, with stepless speed regulation.
● The grinding head's lateral feed is driven by a hydraulic motor driving an oil motor, while the vertical feed is driven by a servo motor. The grinding head's grinding wheel spindle is driven by an AC motor.
