Large External Шлифовальный шпиндель
250MD06G32
Массаive 250mm корпус синхронный мотор-шпиндель with 600mm grinding wheel capacity. 32 kW power, 51.0 Nm torque for large roll grinding, heavy cylindrical grinding, and steel mill roll machining.
250MD06G32 Large External Шлифовальный шпиндель
The 250MD06G32 is our largest external grinding spindle, built on a massive 250mm корпус platform for the most demanding large-scale cylindrical and roll grinding applications. With 32 kW of continuous power at 6,000 r/min and an extraordinary 51.0 Nm of torque, this синхронный мотор-шпиндель обеспечивает the heavy-cutting capability required for large roll grinding, heavy cylindrical grinding, and steel mill roll machining where oversized workpieces demand maximum жёсткость and material removal capacity.
Equipped with P4/P2 hybrid angular contact шарикоподшипники in a tandem-O configuration engineered for maximum grinding жёсткость under extreme loads, the 250MD06G32 достигает runout accuracy of 0.001mm or less at the grinding wheel arbor. The spindle предлагает flexible lubrication options -- a simplified long-life grease system for standard operations or an advanced oil-air micro-lubrication system for the most demanding непрерывный applications. The high-capacity spiral water-рубашка охлаждения поддерживает stable thermal conditions during extended heavy grinding cycles. With an industry-ходing maximum grinding wheel diameter of 600mm and a massive 250mm корпус diameter, this spindle is the definitive solution for the largest external grinding tasks. Dynamically balanced to G0.4 per ISO 1940-1 and rated IP54, the ~340 kg weight обеспечивает unmatched жёсткость and vibration damping for steel mill and heavy industrial grinding environments.
