Product Overview
Designed for precision machining of large workpieces, this series combines robust construction with exceptional operational accuracy, making it a staple in heavy-duty manufacturing environments. With a 1250mm worktable length and head-movable design, the grinders deliver consistent results across various materials, from steel and iron to non-ferrous alloys. Whether for batch production or custom processing, these machines meet the demands of high-precision surface grinding with reliability and efficiency.
Key Features
Precision Grinding Performance
Equipped with a spindle motor of 7.5Kw and a grinding wheel speed of 1440r/min, the Head Movable Surface Grinder achieves a surface roughness of Ra:0.63μm and workpiece surface parallelism of 300:0.008mm. The manual vertical movement of the grinding head offers 0.01mm per graduation precision and 1mm per revolution, ensuring ultra-fine adjustments for critical machining tasks.
Robust & Stable Construction
Built with a net weight ranging from 5300Kg to 5800Kg (gross weight 6000Kg-6500Kg), the grinders feature a heavy-duty base that minimizes vibration during operation. The integrated oil pump motor (4Kw) ensures smooth lubrication of moving parts, extending machine lifespan and reducing maintenance needs.
Versatile Worktable Capacity
The worktable dimensions (L×W×H) vary by model: 1250×500×600mm (M7150), 1250×600×600mm (M7160), and 1250×630×600mm (M7163). With a maximum longitudinal movement of 1350mm and cross movement of 550-680mm, the grinders accommodate large and irregularly shaped workpieces with ease.
User-Friendly Operation
The rapid lifting motor (0.37Kw, 1440r/min) enables quick positioning of the grinding head, while the intuitive handwheel control simplifies precision adjustments. The standardized abrasive wheel size (Φ400×40×127mm) ensures easy replacement and wide availability of consumables.
