Machinist Apprenticeship

Work Description Operating_Machine

Machinists are skilled workers who can transform a block of metal into an intricate part; such as, a gear or piston that meets precise specification. They set up and operate a variety of machine tools to produce precision parts and instruments. Many machines are computer numerically controlled (CNC), which means the machinist uses computers to direct the machine’s operation.

Working Conditions

Most machine shops are well lighted and ventilated. Machinists wear protective equipment such as safety glasses to shield against bits of flying metal and earplugs to protect against machinery noise. They may stand most of the day and may lift moderately heavy work pieces.
