It is mainly applied to machining of machine tool of high speed CNC machiningcenter, and it is suitable to machining of large-scale mold, auto parts andaeronautical parts, etc.
1.Highprecision: The total run-out of internal conical surface at shaft end of electric spindle of machining center is≤0.001 mm; the spindle vibration is ≤1.0 mm/s;HSK, BT handle is adopted; and it has incomparable high precision.
2.High revolution: The maximum revolution of electric spindle ofmachining center reaches as high as 24,000 rpm, which provides powerful supportfor the high-efficiency and high-precision machining of the high speedmachining center.
3.Largetorque: The low speed large torque of electric spindle of the machining centermakes heavy cutting during rough machining of machine tool become possible,which improves the machining efficiency of product.
4.Highconfiguration: Temperature probe, displacement sensor, vibration sensor,proximity switch and closed-loop control encoder is optional for the electricspindle of machining center, and bearing of international famous brand isadopted.
5.Goodextensibility and high compatibility: The electric spindle of machining centerhas good compatibility, and it can be widely applied to the high speedmachining center for machining of various parts.
