Precision Centerless Grinding Machine

• Mineral Casting Bed: The entire machine base is cast in one piece using high-polymer concrete (mineral casting). Its damping and shock absorption capacity is 10 times that of traditional cast iron, with excellent thermal stability, effectively isolating external vibration interference and ensuring long-term accuracy without drift.

• Hydrostatic Spindle System: Both the grinding wheel and guide wheel spindles use high-precision hydrostatic bearings. Supported by a high-pressure oil film, it achieves zero metal contact, zero wear, and unlimited lifespan. The extremely high oil film stiffness completely eliminates micro-chatter in high-speed grinding, which is key to obtaining a mirror-like surface.

• Extra-Long Support Reference: Standard configuration includes 300mm-600mm ultra-wide grinding wheels, combined with an integral carbide support plate, providing continuous support for the workpiece.

• Eliminates "Central Concavity": Regardless of workpiece length, whether it's 2 meters or 4 meters, consistent diameter is guaranteed throughout the entire length, with cylindricity easily controlled within 0.002mm/500mm.

• Efficiency Revolution: The workpiece completes all machining in a single pass through the grinding zone, eliminating the need for reciprocating motion. Single-piece cycle time is measured in seconds, increasing efficiency by over 300% compared to traditional reciprocating grinding.

• Multi-Axis CNC Linkage: Equipped with a high-end [Siemens/Fanuc] CNC system, achieving precise digital control of grinding wheel head feed (X-axis), guide wheel speed/angle (Z/C-axis), and dresser movement.

• Online Measurement Closed-Loop: Integrates a high-precision laser diameter gauge or contact measuring instrument for real-time workpiece dimension monitoring. The system automatically compensates for grinding wheel wear, thermal deformation, and tool wear, ensuring consistent accuracy between the first and last pieces, with a stable CPK value ≥ 1.67.

• Adaptive Grinding: Built-in intelligent algorithm automatically adjusts feed speed based on grinding current feedback to prevent workpiece burn-out or overload.

• Constant Temperature Cooling System: Equipped with a high-precision chiller unit, it independently controls the temperature of grinding fluid, spindle lubricant, and hydraulic system, keeping temperature fluctuations within ±0.5℃ to eliminate the impact of thermal deformation on precision.

• High-Pressure Jet Cooling: Multi-angle nozzle design, combined with a dedicated filtration system, ensures sufficient and clean cooling of the grinding zone, extending grinding wheel life and improving surface quality.
