dc.description.abstract-translatedThe article is focused on the thermal behaviour of a spindle of a milling centre. This is a typical problem of high precision machines, which produce heat as a negative implication of the produce activity. Thermal loading influents productivity and precision of a milling centre. Thermal transfer simulations, computed fluid dynamic solutions and finite element methods in general are vital sources of information about behaviour of machine parts influenced by heat loading. All these methods have common disadvantages, which include the need for a skilled engineer, hardware and software. In general, it causes high cost of a computation. The reduction of costs is solved by a new tool, which uses simple macro-elements with predefined, parametric properties. Reduction of thermal displacement is also a crucial task. Sensitivity study, based on complex case study is able to identify features with significant influence to overall deformation. Complex case consists of detail subcase analysis. Identified parts require modifications for the decreasing of deformations. Results are compared with the new productive computation method based on macro-models. Combination of methods defines productive methodology, which lead to fast prediction and accurate simulation.en
