Surface grinding machine ETW-4010NC

flatfor metal sheetsworkpiece

Overview
The ETW-4010NC series features a movable grinding head design for heavy-duty horizontal peripheral grinding of flat surfaces. It is intended for machining flat parts used in machinery manufacturing, automotive, mold steel plate, tooling and similar industrial applications. Two table options are available: electromagnetic table 690×300 mm (ETW-3069) or 1000×400 mm (ETW-40100).

Main features

• Cast-iron bed for structural rigidity and stable operation.
• Worktable longitudinal (X) travel driven hydraulically with stepless speed regulation.
• Carriage horizontal guide rail uses steel guideway structure for wear resistance and consistent accuracy.
• Grinding-wheel spindle driven by an external low-vibration motor for smooth operation.
• Continuous automatic lubrication for bed and worktable rails; inching lubrication for columns, carriage and grinding-head rails to reduce wear and maintain precision.
