The machinery sector plays an important role in the economy of each country providing the technology, machinery, equipment and production lines for other manufacturing sectors. Nowadays, these companies often introduce also services to their portfolio, thus exceeding the boundary between the manufacturing sector and the service sector. These actions are caused by the global trend of shifting towards a service economy and harsh competitive conditions in the market place. The aim of this article is to assess the condition of the selected group of companies operating in the sector of machinery and industrial equipment manufacturing in terms of technical efficiency, and to examine whether the number of services offered by them correlates with the efficiency score. The analysis was made using DEA (Data Envelopment Analysis), which as a non-parametric method, is widely used for studding the efficiency of both business institutions and public organizations, for which the relationship between inputs and achieved outputs (i.e. the production function) is unknown. Data for the study were drawn from the EMIS (Emerging Market Information Service) database, and the sampling was made in accordance with the DEA methodology taking into account factual and statistical methods. Both, companies that offer a wide range of services and those that limit the range of services to warranty support, were analyzed, and then the results were compared and discussed.

Z uwagi na coraz szersze zastosowania specjalnych trudnoobrabialnych materiałów oraz rosnące wymagania w zakresie wydajności i dokładności oraz jakości warstwy wierzchniej wyrobów obserwuje się dynamiczny rozwój wszystkich podstawowych procesów wytwarzania. Dodatkowym elementem wpływającym na rozwój metod wytwarzania jest coraz szersze stosowanie we wszystkich gałęziach przemysłu Mikro i Nano - Elektro - Mechanicznych - Systemów (MEMS i NEMS), co wymusza produkcję mikro i nanoelementów. Sprostanie powyższym wymaganiom jest możliwe przez intensywny i zharmonizowany rozwój metod wytwarzania przez formowanie, usuwanie oraz dodawanie materiału. W artykule przedstawiono zarys podstawowych problemów wytwarzania ze szczególnym uwzględnieniem procesów niekonwencjonalnych i hybrydowych oraz problem integracji pomiędzy powyżej wymienionymi procesami wytwarzania a mikro i nanotechnologiami.

In the current economic situation, the diversification and competitive of the products offer, globalization of the markets, a continued growth of customers' requirements, improve a product quality, increasing the technical level and improving manufacturing technologies. For all of companies it is a priority to satisfy those customers and market requirements. In the article the main issues related with the evolution of ways of ensuring products quality like: availability-reliability-maintenance relationship, measuring quality aspects through quality characteristics, quality economy in terms of quality costs and quality control, were considered and analyzed. Recommendations for improving of production quality process such as: continuous improvement of product technological conception and constructive one using advanced processes, increasing concerns for quality assurance embodied in the increasing of production prevention costs in total, in parallel with decreasing the latter and continuous training of staff were presented.
