What is a CNC machinist?
A CNC machinist is someone who operates and maintains computer numerical control (CNC) machines to create precision parts and components. They work with various materials such as metal, plastic, or wood.
What does a CNC machinist do?
Usually, a CNC machinist does the following tasks:
- Reading and interpreting technical drawings and blueprints
- Setting up CNC machines and selecting the right tools for the job
- Loading materials into the machine and adjusting machine settings
- Monitoring and operating the machine during production
- Inspecting finished parts to ensure they meet specifications
- Performing routine maintenance and troubleshooting on the machines
What does the day-to-day life of a CNC machinist look like?
A CNC machinist usually works between 7am and 4pm, though the hours may vary depending on the company and the industry. Their day-to-day tasks may include:
- Reviewing job orders and blueprints to understand the required specifications
- Setting up the CNC machine by installing the necessary tools and adjusting machine settings
- Loading materials into the machine and starting the production process
- Monitoring the machine's operation and making any necessary adjustments
- Inspecting finished parts to ensure they meet quality standards
- Performing basic maintenance tasks on the CNC machine, such as cleaning and lubricating parts
Where does a CNC machinist work?
CNC machinists can work in various settings, including:
- Manufacturing companies: Many manufacturing companies have their own machine shops where CNC machinists operate and maintain the machines to produce parts and components.
- Aerospace industry: CNC machinists are commonly employed in the aerospace industry to create precise components for aircraft and spacecraft.
