Precision assemblers build complex products from manufactured parts.

Precision assemblers are skilled workers. They perform a series of complex tasks to produce products such as:

• Cars
• Watches and clocks
• Computers

Precision assemblers may work on the parts that go into products, or on the final assembly of finished products. Precision machine builders put together engines, turbines, and many types of machinery. Assemblers of electrical and electronic equipment build missile control systems, radio or test equipment, and radar. Other assemblers produce and test unusual devices, such as ejection seat mechanisms.

Precision assemblers read drawings and blueprints to learn about the item they will work on. Some assemblers shape parts on metalworking machines or using hand and power tools. Most use parts made by other workers. Assemblers lay out the parts for assembly. They may drill or tap holes in parts to provide openings for wiring. In electrical equipment, they connect wiring according to diagrams.

Precision assemblers inspect and test parts for defects. Some assemblers repair or replace defective parts. Others adjust voltages or redo wiring. Assemblers use a variety of hand and power tools and precision instruments to repair and test parts.

Some assemblers write reports about production, time, and component waste. Others pack finished units for shipment. They may teach customers how to install and maintain their products. They may work with engineers to test products or solve problems, or in teams with other assemblers.
