ensuring consistent precision even in high-intensity machining scenarios. It is an indispensable tool for machine tool manufacturing, machining, and mold industries, where accuracy and reliability are critical.
Key Features
Stepped Gantry Rigid Frame
The machine adopts a rigid frame composed of a heavy-duty bed, stable columns, and a reinforced Crossbeam. This structural design provides sufficient dynamic stiffness, minimizing vibration during high-speed movements and guaranteeing machining accuracy. Whether the worktable is moving longitudinally or the carriage is sliding horizontally, the frame maintains stability to avoid deformation.
Flexible CNC & Hydraulic Control
Horizontal movement of the carriage and vertical movement of the slide are fully controlled by CNC, enabling precise positioning and feed adjustments.
The worktable’s longitudinal movement is driven by a hydraulic automatic speed control system, with a speed range of 5~25 m/min. This ensures smooth, efficient movement tailored to different machining requirements.
High Precision Machining Capabilities
Minimum vertical feed of 0.005 mm, supporting ultra-fine precision grinding for critical surfaces like rail surfaces and precision planes.
Consistent spindle performance with optimized grinding wheel size (Φ500 × 75/100/150 × Φ203 mm) ensures uniform material removal and superior surface finish.
Wide Workpiece Compatibility
With maximum grinding workpiece sizes ranging from 2000×1200×600(800) mm to 8000×2200×800 mm, the series accommodates small to large-scale workpieces. The worktable maximum load weight (including magnetic chuck) reaches up to 30,000 kg, meeting the needs of heavy-duty machining tasks.
