Industrial Machinery Mechanic or Maintenance Worker or Millwright

Industrial machinery mechanics and machinery maintenance workers maintain and repair factory equipment and other industrial machinery, such as conveying systems, production machinery, and packaging equipment. Millwrights install, dismantle, repair, reassemble, and move machinery in factories, power plants, and construction sites.

Industrial machinery mechanics, machinery maintenance workers, and millwrights typically do the following:

• Read technical manuals to understand equipment and controls
• Disassemble machinery and equipment when there is a problem
• Repair or replace broken or malfunctioning components
• Perform tests and run initial batches to make sure that the machine is running smoothly
• Detect minor problems by performing basic diagnostic tests
• Test malfunctioning machinery to determine whether major repairs are needed
• Adjust and calibrate equipment and machinery to optimal specifications
• Clean and lubricate equipment or machinery
• Move machinery and equipment

Industrial machinery mechanics, machinery maintenance workers, and millwrights held about 483,200 jobs in 2021. Employment in the detailed occupations that make up industrial machinery mechanics, machinery maintenance workers, and millwrights was distributed as follows:

Industrial machinery mechanics	384,800
Maintenance workers, machinery	58,500
Millwrights	39,900

The largest employers of industrial machinery mechanics, machinery maintenance workers, and millwrights were as follows:

Manufacturing	53%
Wholesale trade	12
Commercial and industrial machinery and equipment (except automotive and electronic) repair and maintenance	10

Injuries and Illnesses

Working with industrial machinery can be dangerous. To avoid injury, workers must follow safety precautions and use protective equipment, such as hardhats, safety glasses, steel-toed shoes, gloves, and earplugs.

Work Schedules

Most industrial machinery mechanics and machinery maintenance workers are employed full time during regular business hours. However, mechanics may be on call and work night or weekend shifts. Overtime is common, particularly for mechanics.

Industrial machinery mechanics, machinery maintenance workers, and millwrights typically need a high school diploma. Industrial machinery mechanics and machinery maintenance workers also usually need a year or more of training after high school.

Most millwrights go through an apprenticeship program that lasts about 4 years.

Education

Industrial machinery mechanics, machinery maintenance workers, and millwrights generally need at least a high school diploma or equivalent. Some mechanics and millwrights complete a 2-year associate’s degree program in industrial maintenance. Industrial maintenance programs may include courses such as welding, mathematics, hydraulics, and pneumatics.

Training

Industrial machinery mechanics and machinery maintenance workers typically receive more than a year of on-the-job training. Industrial machinery mechanics and machinery maintenance workers learn how to perform routine tasks, such as setting up, cleaning, lubricating, and starting machinery. They also may be instructed in subjects such as shop mathematics, blueprint reading, proper hand tool use, welding, electronics, and computer programming. This training may be offered on the job by professional trainers hired by the employer or by representatives of equipment manufacturers.

Most millwrights learn their trade through a 3- or 4-year apprenticeship. For each year of the program, apprentices must have at least 144 hours of relevant technical instruction and up to 2,000 hours of paid on-the-job training. On the job, apprentices learn to set up, clean, lubricate, repair, and start machinery. During technical instruction, they are taught welding, mathematics, how to read blueprints, and machinery troubleshooting. Many also receive computer training.

After completing an apprenticeship program, millwrights are considered fully qualified and can usually perform tasks with less guidance.

Employers, local unions, contractor associations, and the state labor department often sponsor apprenticeship programs. The basic qualifications for entering an apprenticeship program are as follows:

• Minimum age of 18
• High school diploma or equivalent
• Physically able to do the work

Industrial machinery mechanics and maintenance workers and millwrights typically have an interest in the Building, Thinking and Organizing interest areas, according to the Holland Code framework. The Building interest area indicates a focus on working with tools and machines, and making or fixing practical things. The Thinking interest area indicates a focus on researching, investigating, and increasing the understanding of natural laws. The Organizing interest area indicates a focus on working with information and processes to keep things arranged in orderly systems.

If you are not sure whether you have a Building or Thinking or Organizing interest which might fit with a career as an industrial machinery mechanic and maintenance worker and millwright, you can take a career test to measure your interests.

Industrial machinery mechanics and maintenance workers and millwrights should also possess the following specific qualities:

Manual dexterity. When handling very small parts, workers must have a steady hand and good hand–eye coordination.

Mechanical skills. Workers must be able to reassemble large, complex machines after finishing a repair.

Technical skills. Industrial machinery mechanics and maintenance workers and millwrights use technical manuals and sophisticated diagnostic equipment to figure out why machines are not working.  

Troubleshooting skills. Industrial machinery mechanics and maintenance workers and millwrights must observe and properly diagnose and fix problems that a machine may be having.

The median annual wage for industrial machinery mechanics, machinery maintenance workers, and millwrights was $59,380 in May 2021. The median wage is the wage at which half the workers in an occupation earned more than that amount and half earned less. The lowest 10 percent earned less than $37,260, and the highest 10 percent earned more than $78,900.

Median annual wages for industrial machinery mechanics, machinery maintenance workers, and millwrights in May 2021 were as follows:

Millwrights	$60,330
Industrial machinery mechanics	59,840
Maintenance workers, machinery	48,900

In May 2021, the median annual wages for industrial machinery mechanics, machinery maintenance workers, and millwrights in the top industries in which they worked were as follows:

Manufacturing	$59,820
Construction	59,770
Wholesale trade	56,900
Commercial and industrial machinery and equipment (except automotive and electronic) repair and maintenance	48,270

Most industrial machinery mechanics and machinery maintenance workers are employed full time during regular business hours. However, mechanics may be on call or assigned to work night or weekend shifts. Overtime is common, particularly for mechanics.

Overall employment of industrial machinery mechanics, machinery maintenance workers, and millwrights is projected to grow 14 percent from 2021 to 2031, much faster than the average for all occupations.

About 53,200 openings for industrial machinery mechanics, machinery maintenance workers, and millwrights are projected each year, on average, over the decade. Many of those openings are expected to result from the need to replace workers who transfer to different occupations or exit the labor force, such as to retire. 

Employment

Projected employment of industrial machinery mechanics, machinery maintenance workers, and millwrights varies by occupation (see table).

The continued adoption of automated manufacturing machinery is expected to create jobs for these workers, as they will be needed to help keep machines in good working order. The use of automated conveyors to move products and materials in factories is likely to be an area of high demand for these workers, because the conveyor belts, motors, and rollers need regular care and maintenance.
