170XDJ12G40 HC80 Grinding/Milling Spindle
The 170XDJ12G40 HC80 is a versatile combined grinding and milling spindle engineered for multi-process machining operations. With 40 kW of continuous power at 12,000 r/min and 31.8 Nm of torque, this high-performance spindle seamlessly transitions between grinding and milling tasks, making it ideal for tool grinding, profile grinding, and applications requiring both grinding wheel and milling tool capabilities within a single setup.
Equipped with a precision HC80 grinding wheel flange tool interface and P4/P2 hybrid angular contact ball bearings in a tandem-O configuration, the 170XDJ12G40 achieves runout accuracy of 0.001mm or less for exceptional surface finish quality. The advanced oil-air micro-lubrication system ensures reliable bearing performance across the complete speed range. The spiral water-cooling jacket maintains stable thermal conditions during extended grinding and milling cycles. With a maximum grinding wheel diameter of 300mm and a robust 170mm housing, this spindle delivers the versatility and precision demanded by modern tool and profile grinding workshops. Dynamically balanced to G0.4 per ISO 1940-1 and rated IP54, the ~160 kg weight provides excellent rigidity and vibration damping for precision multi-process machining.
