What does a CNC Lathe Machinist do?
Published 4 min read
A CNC lathe machinist is responsible for operating a computer numerical control (CNC) lathe to fabricate parts from metal or plastic. The machinist must be able to read and interpret blueprints or other engineering drawings in order to produce the desired product.
CNC Lathe Machinist job duties include:
- Read and interpret blueprints, engineering drawings, and other specifications to determine machining operations, setup requirements, control settings, and tolerances
- Plan the sequence of operations and setup requirements in order to create a smooth workflow
- Select appropriate cutting tools for the material being machined and the desired finish
- Mount, align, and secure workpiece on spindle or in chuck before starting the machine
- Set controls to regulate speed, feed rate, depth of cut, and cutting angle according to knowledge of metal properties and shop mathematics
- Start machine and observe operation to detect malfunctions or out-of-tolerance machining
- Make necessary adjustments to correct problems, using hand tools if needed
- Stop machine when completed workpiece is ejected or when an error is detected
- Measure workpiece dimensions to ensure adherence to specifications using precision measuring instruments such as calipers or micrometers
- Perform regular maintenance on the CNC lathe such as cleaning, lubricating, and replacing worn parts
CNC Lathe Machinist Job Requirements
Most CNC lathe machinists have a high school diploma and receive on-the-job training that lasts about a month. Some machinists may receive formal training at a technical school or community college. Many machinists become certified through the National Institute for Metalworking Skills (NIMS). Certification shows employers that the machinist has the skills needed to do the job. To maintain their certification, machinists must keep their skills up to date by taking continuing education courses. Most CNC lathe machinists have at least three years of experience.

How to become a CNC Lathe Machinist
A CNC lathe machinist is a skilled tradesperson who operates a computer numerical control (CNC) lathe to fabricate parts from metal, plastic or other materials. The machinist must be able to read and interpret engineering drawings and blueprints, as well as understand the properties of various materials. They must also be familiar with the various cutting tools and how to properly operate the CNC lathe.
Becoming a CNC lathe machinist typically requires completing a vocational program at a community college or technical school. Many machinists also receive on-the-job training to learn the specific operating procedures of the CNC lathes they will be using. Some employers may require certification from the National Institute for Metalworking Skills (NIMS).
Once employed, CNC lathe machinists typically start out performing simple tasks under the supervision of more experienced workers. With experience and training, they can advance to setting up and programming the CNC lathes, as well as running multiple machines simultaneously. The most experienced and skilled machinists may eventually become supervisors or managers.
