Rigidity of high-speed motor spindles

Werkstatt und Betrieb, 1999
Rigidity of high-speed motor spindles. The most relevant factors for the static operational rigidity of motor spindles were analysed, and the finite element method was used for calculating the effects of configuration, type, prestress and heat-up of bearings as well as of the temperature range of the spindle nose on the operational rigidity of motor ...

Design of intelligent spindle for high speed machining

Proceedings of the Second International Conference on Intelligent Processing and Manufacturing of Materials. IPMM'99 (Cat. No.99EX296), 1999
Summary form only given. The spindle is the most important component in a high speed CNC machine tool. Its thermal and dynamic behaviors are almost decided by the drive system and the support system of the spindle. Some special requirements for high speed spindles must be satisfied; C-axis control is also required.

A thermal model for high speed motorized spindles

International Journal of Machine Tools and Manufacture, 1999
Lack of a more complete understanding of the system characteristics, particularly thermal effects, severely limits the reliability of high speed spindles to support manufacturing. High speed spindles are notorious for their sudden catastrophic failures without alarming signs at high speeds due to thermal problems.

Stability Analysis of Machining with Spindle Speed Variation

Advanced Materials Research, 2011
In this paper the chatter stability of turning and full-immersion milling operations with spindle speed variation is studied. We present a method to calculate the stability lobes in the limit of very low and very high frequencies of the delay modulation. These approximations help to classify the results of numerically exact methods, as for example semi-
