NAGASEi SGX‑126 | HIGH PRECISION DOUBLE COLUMN TYPE SURFACE GRINDING MACHINE

Overview

High precision × High efficiency × Space-saving
A New Generation Mid-Range Double-Column Grinding. “Achieve high-precision surface grinding with unmatched productivity” Ideal for machining medium-sized mold plates and precision components.

Chuck size	1200 × 600 mm
Table travel (X × Y)	1500 × 695 mm
Min. vertical increment (Z)	0.0001 mm
Wheel size (OD × W × ID)	φ250–510 × 38–75 × φ127 mm

Stable precision High‑rigidity structure suppresses thermal drift and deflection.

Operator friendly Selectable Neo / Zero CNC controls for simple operation or advanced conversational grinding.

Space‑saving 50% smaller installation area versus a conventional single-column machine under the maker’s comparison conditions.
