When a production line shuts down, a corporation loses money. Maintenance machinists are critical to maintaining output. Machinery maintenance workers, also known as industrial mechanics or maintenance machinists, must be able to diagnose and rectify small faults as well as restore broken machines. As a result, preventive maintenance, inspection, and testing machine performance are all important aspects of the work. 

When a machine fails, the maintenance machinist must diagnose the problem, disassemble the machine, repair or replace the defective parts, and reassemble the machine. Maintenance mechanics may be called to the facility at night or on weekends for emergency repairs since factories and other facilities cannot afford industrial machinery malfunctions. 

Machine repair personnel frequently work overtime. Mechanical ability and physical dexterity are essential qualities for workers in this field. Good physical conditioning and agility are essential since repairs may necessitate lifting large objects or climbing to reach equipment positioned high above the floor. 

Machine mechanics can enter the trade through a four-year apprenticeship supported by a labour organisation. Other workers begin as helpers and gradually gain the necessary abilities. Companies rely on skilled workers and high-quality machinery. The machinery maintenance worker's task is to ensure that the equipment runs properly.
