A computation system dedicated for machine tool spindle drives is presented which integrates a FDM model with a FEM model. Modelling of heat exchange through coolers are discussed, as well as modelling of heat exchange between cooling-lubricating oil and gear transmissions, shafts and headstock walls. In modelling of heat exchange inside headstock, the use of additional elements - type "Fluid" and "Air" - is proposed. Sample modelling results are presented concerning a headstock from a drilling-milling machine tool for machining with high loads and are compared with experimental data.
