A2001760 Heavy-Duty Grinding Spindle
190mm | 90 N·m Torque | Engineered for High-Precision, High-Rigidity Grinding Applications
The A2001760 is a professional-grade electric spindle designed specifically for demanding grinding machines, such as cylindrical grinders, roll grinders, and large surface grinders. Built with a robust 190mm housing, it delivers exceptional torque (up to 90 N·m) and rigidity (1000 N/µm radial stiffness) necessary for stable, high-precision material removal on hardened steels, alloys, and large workpieces. Featuring ultra-precision bearings and optimized for horizontal installation, this spindle is the core component for achieving superior surface finishes, tight tolerances, and reliable performance in industrial grinding operations.
Technical Overview
This spindle is engineered from the ground up for the unique challenges of grinding, prioritizing process stability, thermal control, and precision over high rotational speed. Its high torque output and extreme radial stiffness minimize vibration and deflection during the grinding process, which is critical for achieving fine surface finishes and maintaining geometric accuracy on large or heavy components.
Core Performance Advantages
- High Torque & Power for Efficient Stock Removal: Delivers 90 N·m of torque in S6 duty cycle, enabling powerful and efficient grinding even on tough materials, reducing cycle times for roughing and finishing operations.
- Exceptional Rigidity for Grinding Stability: An outstanding radial stiffness of 1000 N/µm provides a rock-solid foundation that is essential for minimizing chatter and vibration, ensuring consistent part geometry and superior surface quality.
- Ultra-Precision Bearing System: Utilizes high-precision, P4-grade angular contact ball bearings (90BNR10 & 60BNR10 series) with grease lubrication, specifically selected for grinding applications to ensure smooth, quiet operation, long service life, and minimal runout.
- Optimized for Grinding Processes: The 3600 rpm maximum speed is tailored for optimal grinding wheel performance across a wide range of diameters and materials, balancing cutting speed with surface finish requirements.
- Robust Thermal Management: A dedicated liquid cooling system (>10 L/min) effectively manages heat generated during continuous grinding cycles, maintaining spindle accuracy and protecting critical components.
