types of grinding inner circle

Grinding inner circle divided into the following four categories: speed electric aerostatic bearing inner circle grinding, grinding inner circle of mechanical transmission, pneumatic and electric grinding inner cutoff wheel  circle inner circle grinding.
Aerostatic bearing speed electric grinding inner circle: The aerostatic bearing (supply pressure is 40 ~ 65MPa), grinding system rigidity, both electric grinding characteristics, speed up 180000R/MIN, suitable for grinding a ~ 10MM hole.
Inner circle grinding mechanical transmission: mainly by the spindle, bearings, sleeve body shell, flat supporting pulleys and other components. Then, after replacement of the long axis, is used wet diamond polishing pads  to grind different bore diameter and length, for comparison, the use of low speed, the speed is generally lower than 2000R/MIN.Wind-driven inner circle grinding: spindle with a turbine driven by compressed air turbine rotates the spindle speed, spindle speed reaches 10000R/MIN. Moreover, small vibration, pressure can be adjusted stepless. And with regulators, filters and other accessories.Electric grinding inner circle: A three-phase floor polisher pads  asynchronous motor direct drive, and another by a high-frequency electric motor driven spindle speed of up to 50000 ~ 90000R/MIN. Output power is larger, instantaneous overload, speed characteristics hard, little vibration.
