How to Become a Machinist
Machinists set up and operate machine tools (lathes, milling machines, grinders) to produce precision metal parts for manufacturing, aerospace, and defense industries.
Steps to Become a Machinist
- Meet basic requirements — You must be at least 18 years old with a high school diploma or GED. A strong foundation in math, physics, and shop classes helps.
- Apply to an apprenticeship program — Machinist apprenticeships last 4 years and combine on-the-job training with classroom instruction. Apply through your local union (IBEW, UA, etc.) or a non-union contractor program. You earn while you learn from day one.
- Complete required training — Complete 8000 hours of on-the-job training and related classroom instruction.
- Earn certifications — Required certifications include: NIMS Machining certifications, CNC programming certifications, Blueprint reading certification.
- Pass the journeyman exam — After completing your apprenticeship, pass the journeyman licensing exam in your state to earn full journeyman status and pay.
