The purpose of this article was to describe a case of autonomous maintenance implementation in a pilot area of a metal mechanical industry company. The TPM – Total Productive Maintenance is a managerial technology that can help companies to reduce failures and breakages of machines. One of the most important issues of TPM is autonomous maintenance. The method of research was the case study. A program of twelve points was structured and adopted as stand-alone maintenance deployment guide. The program began in a pilot area, including three machining centers. The main results of the pilot program were: increasing by more than 700% the Mean Time between Failure, reducing by more than 40% in the Mean Time to Repair, as well as the consequent increase of more than five percentage points on the availability of the three machines and almost 60% reduction in the cost of maintenance materials. The main conclusion was that the TPM, and in particular the autonomous maintenance, can increase the efficiency of maintenance as strategic factor, which enhances the competitiveness of manufacturing in industrial companies.
