A high-speed precise machining centre spindle unit model, based on two computation methods: the finite element method and the finite difference method is presented. The model based precise high speed spindle bearings unit behaviour and optimal operating characteristics estimation have been discussed. The modelling methods allow one to evaluate a design from thermal, stiffness and life cycle points of view. The behaviour of three machining centre headstocks with: an electrospindle on rolling bearings, a conventional spindle and an electrospindle on aerostatic bearings are modelled and analysing. The bearing units and cooling system influence on machine tool preciseness has been described as well as volumetric error estimation and compensation results.
