Job Description
Machinists operate machine tools to create precision metal parts and instruments. On a day-to-day basis, they read blueprints, set up and adjust machines such as lathes, milling machines, and grinders, and ensure parts meet exact specifications. They work with both manual and CNC (Computer Numerical Control) machinery to produce components used in industries like aerospace, automotive, and manufacturing.
Key Responsibilities
- Interpreting technical drawings and blueprints to determine machining requirements.
- Setting up and operating various machine tools including CNC lathes, mills, and grinders.
- Measuring finished parts to ensure accuracy using precision instruments such as micrometers and calipers.
- Maintaining and calibrating machinery to ensure optimal performance.
- Troubleshooting machine malfunctions and making necessary adjustments.
- Following safety protocols to maintain a safe working environment.
