Spindle, spindle power supply Shijiazhuang, Bot Seiko (certified merchants) are provided by Shandong Bot Seiko Corporation. Shandong Bot Seiko Co., Ltd. (www.jsinfo.com.cn) is specialized in the "ball screw, lead screw, linear guide, spindle," the enterprise, the company of "honesty, hard service" concept, for You provide the most quality products and services. Welcome to inquire! Contact: Zhang complete. Relationship between the power or torque and the rotational speed of the spindle transmission. When the machine is in continuous operation, the spindle speed in the 437 ~ 3500r / min Spindle price range, Shijiazhuang, Baoding spindle transfer all power 11kW electric motor spindle price for spindle constant power region Ⅱ (solid line). In this region, the maximum output torque of the spindle (245N.m) with the increase of the rotational speed of the spindle becomes small. Spindle speed is within 35 ~ 437r / min range, the output torque of the same spindle, the spindle of the constant torque region called Ⅰ (solid line). Baoding supply electric spindle, spindle in this region that can deliver power with lower spindle speed decreases. Spindle usually hybrid bearing, composite ceramic bearings or electromagnetic levitation bearings. Hybrid bearing with high stiffness and damping, can greatly improve the processing efficiency, processing quality, longer tool life, reduce processing costs, which probably infinitely long bearing life. Currently more complex ceramic bearings in electric spindle cell applications, this use of hot rolling element bearing Si3N4 ceramic ball bearing rings still steel, high degree of standardization, structural alterations of the machine is small, easy to maintain. High-speed maglev bearing good electrical performance, high precision, easy to implement diagnostic and on-line monitoring, measurement and control systems, but due to the complexity of the solenoid, the bearings are very expensive, and the long-term high, has not been widely used.
