The Okamoto ACC‑16.32DX is a 16" × 32" automatic hydraulic surface grinder that uses an integrated servo drive and CNC control for precise feed rates and table loads up to 1,540 lb. Common failure points on this class of machines include hydraulic pump leaks or pressure loss, servo motor overheating or encoder mis‑alignment, and controller board faults such as power supply brownouts or communication errors with the CNC module. First‑check steps: verify that the main 48/120 V supply is stable and that all fuses and circuit breakers are intact; inspect the hydraulic lines for leaks, blockages, or worn seals; and review any error codes displayed on the control panel to pinpoint drive or controller issues.[oss-gpt-20b]
