The SDVEDON SGA4080AHD/NC2 is a high-performance saddle type surface grinder designed for precision flat grinding applications. Available in two variants (AHD and NC2), it combines robust construction, advanced control, and reliable performance to meet the demands of workshops and production facilities.
Both models feature a heavy-duty cast iron saddle type structure for stability during high-precision grinding. The longitudinal axis is hydraulically driven for smooth, consistent movement, while the vertical axis uses an AC servo motor for precise control. The NC2 model adds an AC servo motor to the cross axis for enhanced accuracy and flexibility.
Equipped with a GS-PLC touch controller, the machine offers intuitive operation and customizable grinding cycles. It comes standard with a magnetic chuck, coolant system, and full set of accessories, making it ready for immediate use. Ideal for grinding flat surfaces of various materials, including steel, cast iron, and non-ferrous metals.
- Cast Iron Construction: Heavy-duty cast iron bed and saddle for vibration damping and long-term stability.
- Precision Guideways: High-quality linear guideways ensure smooth movement and consistent accuracy.
- Hydraulic Longitudinal Drive: 7~23m/min speed range for efficient material removal and fine finishing.
- AC Servo Vertical Axis: Precise control of wheel head movement with auto feed options from 0.005 to 0.05mm/stroke.
- Cross Axis Options: AHD model with motor drive, NC2 model with AC servo drive for enhanced positioning accuracy.
- GS-PLC Touch Controller: Intuitive touchscreen interface for easy setup and operation.
- Multiple Feed Modes: Adjustable auto feed, rapid speed, and handwheel feed for different grinding operations.
- Magnetic Chuck: 400x800mm magnetic chuck included for secure workpiece holding.
The machine has passed CE & ISO 9001 international quality system certification, complying with global industrial safety and quality standards. Each unit undergoes strict factory precision inspection before delivery. SDVEDON provides 1-year full machine warranty and lifelong free technical support, including installation guidance and maintenance service.
