Internal Шлифовальный шпиндель
100MD60Y7.5
High-power internal grinding spindle. 60,000 r/min with 7.5 kW output. High-frequency asynchronous motor, water-cooled, ideal for medium to large bore grinding.
100MD60Y7.5 Internal Шлифовальный шпиндель
The 100MD60Y7.5 is a powerful internal grinding spindle designed for medium to large bore grinding applications requiring both high speed and substantial power. Работает на скорости до to 60,000 r/min with a robust 7.5 kW high-frequency asynchronous motor, this spindle обеспечивает the wheel surface speeds and material removal capability needed for efficient internal grinding of bearing корпусs, hydraulic cylinders, gear bores, and other precision internal имеет.
P4 precision angular contact шарикоподшипники provide the жёсткость and accuracy necessary for consistent sub-micron runout at the grinding pin interface. An efficient water-jacket cooling system manages the thermal loads generated during sustained operation, maintaining geometric stability and preventing thermal drift. The 100mm корпус diameter обеспечивает good stiffness while allowing access to bores typically 20mm and larger. Weighing approximately 22 kg, the 100MD60Y7.5 is designed for integration into CNC internal grinding machines, universal grinding machines with internal grinding attachments, and specialized bore grinding equipment.
