Abstract
High-speed machining can significantly improve productivity and reduce production costs, is a very promising advanced manufacturing technology. The first condition to achieve high-speed processing of high quality high-speed machine tools, and high-speed electric spindle speed CNC machining center technology and key components. Electric spindle system static and dynamic stiffness is one of the main challenges affecting performance. This article describes the working principle of the spindle and key technologies. Then, determine a reasonable overall structure of the spindle, respectively, spindle motor, encoder, rotor, stator and cooling systems and other components were designed, produced assembly drawings, part drawings and design specifications and other design documents. Finally, the rotation of the spindle shaft and bearings for a detailed analysis and verification, calculations show that the design meets the requirements of the spindle.

Key Words:Machining center；Electrical spindle；Bearing
