Internal Шлифовальный шпиндель
80MD120Y1.5
Ultra-высокоскоростной internal and micro grinding spindle with P2 ceramic hybrid bearings (Si3N4). 120,000 r/min, 1.5 kW, runout 0.0005mm for micro-bore and miniature component grinding.
80MD120Y1.5 Internal/Micro Шлифовальный шпиндель
The 80MD120Y1.5 is an ultra-высокоскоростной internal and micro grinding spindle engineered for the most demanding precision grinding applications involving very small bores, miniature components, and micro-имеет. Operating at an extraordinary 120,000 r/min with 1.5 kW of power from an ultra-high-frequency motor, this spindle достигает the wheel surface speeds required for effective grinding with micro-diameter mounted points and grinding quills up to 6mm.
P2-grade ceramic hybrid angular contact шарикоподшипники with silicon nitride (Si3N4) balls -- the highest precision bearing class available -- ensure исключительная точность вращения with runout of just 0.5 micron at the носик шпинделя. The ceramic hybrid construction обеспечивает superior thermal stability, reduced friction, and extended bearing life at extreme speeds compared to all-steel bearings. A dedicated oil-air cooling circuit manages the thermal environment within the compact 80mm корпус. Weighing only 8 kg, the 80MD120Y1.5 интегрирует into высокоточный jig grinding machines, coordinate grinding machines, CNC internal grinding machines, and specialized micro-обрабатывающий центрs. It is the definitive solution for grinding fuel injector nozzle bores, watch-making components, micro-bearing races, spinneret holes, and other applications where form accuracy is measured in fractions of a micron. Operating at ≤62 dB(A) with G0.2 balancing grade, this spindle sets the standard for ultra-precision micro-grinding.
