Also, a machine that is not properly repaired and maintained may damage the product or injure the operator. All of these factors cost companies money. Industrial machinery mechanics are often called industrial machinery repairers or maintenance machinists. They spend much of their time working on machines before they break down. This includes keeping machines and their parts well oiled, greased, and cleaned.
Mechanics regularly inspect machinery and check how they are working.
For example, they adjust and calibrate automated manufacturing equipment, such as industrial robots. They also rebuild parts of other industrial machinery. By keeping records, mechanics try to find problems before they occur. This way, they can work on equipment before it breaks down and factory production is interrupted. Maintenance mechanics must be able to spot minor problems.
