The general trend towards complete machining calls for tool spindles with a measurably greater range of applications so that it is no longer necessary to change the spindle during the machining operation. The search is for an adaptable universal-application high-frequency motor spindle that can be kept under dynamic control in various types of machine models allowing briefer set-up times with a simple tool change. The only way to expand or break through the existing limitations is with a spindle design that can be statically and dynamically manipulated. A motor spindle design with an additional magnetic bearing for enhancement of static and dynamic spindle stiffness is presented. The magnetic bearing is located between front and real roller bearings.
