This Okamoto ACC 1224ST Surface Grinder is a precision Japanese 3-axis hydraulic-feed toolroom surface grinder built around a 12" x 24" magnetic chuck and matching 12" x 24" working table, with 29.5" of longitudinal table travel, up to 13.7" of vertical clearance between the spindle wheel and the table, and a 5 HP spindle that runs a 12" x 1.5" x 5"-bore wheel at 3,600 RPM. The hydraulic table-feed system takes the operator out of the long pass and lets a single setup produce repeatable surface finish on dies, fixtures, gauges, plates, and small-to-mid-size production work — and the grinder supports a max table load of 925 lbs including the chuck. Compared to manual hand-feed surface grinders in the 12 x 24 class, the Okamoto ACC series adds hydraulic longitudinal table feed plus Okamoto's standard auto-downfeed and auto-crossfeed cycle, which turns the same chuck capacity into a true production grinder rather than an operator-tended toolroom helper. The ACC 1224ST is well-known in tool-and-die and mold shops for holding accuracy over long production runs, and at a 925 lb chuck-and-workpiece capacity it can comfortably handle bolster plates, mold details, and gauge bars that smaller 6 x 12 and 8 x 18 grinders simply cannot accept.
