Shandong Bot Seiko Co. spindle assembly performance indicators are mainly rotational accuracy, rigidity and speed adaptation. ① rotation accuracy: radial and axial rotation of the spindle in the direction of the impact of precision appears beating, is mainly determined by the quality of the manufacturing and assembly of the spindle and bearings. ② dynamic and static rigidity: The main decision of the bending stiffness of the spindle, bearing stiffness and damping. ③ speed adaptation: the maximum permissible speed and Zhoushan Spindle speed range prices, mainly determine the structure and lubrication to the bearings, and cooling conditions. Drive spindle motor spindle are used AC asynchronous induction motor, because it is used in high-speed electric spindle machine tools Lishui supply, when starting from standstill turn quickly accelerates to tens or even hundreds of thousands of revolutions per minute Quzhou Spindle price, starting torque, and therefore normal motor starting current to exceed the rated current of 5 to 7 times. Its drive a inverter drive and vector control drive drive in two. The drive control for constant torque characteristics of the inverter drive, the output power is proportional to the torque. The latest machine uses advanced inverter transistor technology to achieve stepless spindle. Vector control drive machine drive control for constant torque at low end of the drive, in the high-speed end to the constant power drive; Zhoushan supply electric spindle, spindle, Shandong by Shandong Bot Bot Seiko Seiko Corporation. Shandong Bot Seiko Co., Ltd. (www.jsinfo.com.cn) strong, credible, Shandong Jining machining industry has accumulated a large number of loyal customers. The company better work attitude and constantly improving innovative ideas will lead Bot Seiko and you hand into the brilliant, for a better future!
