The SGA-4080 AHD is a heavy-duty, high-precision hydraulic surface grinding machine featuring an automated downfeed and crossfeed servo system (AHD configuration). Built on a rigid cast-iron saddle-moving structure, it delivers smooth hydraulic longitudinal motion and exceptional micro-feed accuracy. Driven by a powerful 5.5kW spindle motor and capable of handling up to 500 kg workloads, it is built for precision mold making, toolroom finishing, and heavy industrial component production.
