Inner circle grinding mechanical transmission

 Inner circle grinding is generally divided into four types: wind-driven inner circle grinding, high-speed electric aerostatic bearing inner circle grinding, mechanical drive and electric grinding inner circle inner circle grinding.Wind-driven inner circle grinding: spindle with  concrete saw blades  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.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 to grind different bore diameter and  granite polishing pads length, for comparison, the use of low speed, the speed is generally lower than 2000R/MIN.Electric grinding inner circle: A three-phase 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.enerally the heat generated by the grinding process will burn the workpiece, so you need to use coolant to promptly take the heat, this is called wet. However, grinding tools is a special application, as part of more complex shape, machining accuracy is relatively high, most of the processes set by manually, there is no way to use wet methods. In theory, the hardness of steel molds are high, and SG monocrystalline corundum grinding wheel is the best option.
