What does a Lathe Machinist do?
Published 4 min read
A lathe machinist is responsible for operating a lathe to cut, sand, or drill metal pieces. They must have knowledge of how to use the machine and be able to read blueprints or other instructions.
Lathe Machinist job duties include:
- Read and interpret blueprints, engineering drawings, and sketches to determine material requirements and specifications
- Select the appropriate lathe for the job, based on factors such as material to be machined, tolerance requirements, surface finish requirements, and production quantity
- Mount workpieces onto the lathe chuck or faceplate, using clamps, fixtures, setscrews, or other methods
- Align workpieces using various measuring instruments such as calipers, micrometers, and dial indicators
- Set up and operate lathes to turn cylindrical or tapered workpieces, drill, ream, thread, or knurl workpieces
- Feed workpiece into the cutting tool while it is rotating to perform various machining operations such as turning, boring, facing, and threading
- Monitor lathe operation to detect potential problems such as tool breakage or excessive vibration
- Adjust lathe controls to regulate speed, feed rate, cutting depth, and direction of cut
- Change cutting tools when necessary
Lathe Machinist Job Requirements
A lathe machinist typically needs a high school diploma or equivalent, although some jobs may require postsecondary education, and most machinists receive on-the-job training. Some machinists learn their trade through apprenticeship programs. Apprenticeship programs usually last 3 to 4 years and combine technical instruction with on-the-job training. Many community colleges offer certificate or associate's degree programs in machine technology, which can be helpful for getting a job as a machinist.

How to become a Lathe Machinist
A lathe machinist is a skilled tradesman who operates a lathe, a machine that spins a workpiece while it is being worked on by cutting tools. Lathe machinists are employed in a variety of industries, including the automotive, aerospace, and manufacturing sectors.
Becoming a lathe machinist typically requires completing an apprenticeship or vocational training program. Some machinists may also choose to earn a bachelor's degree in engineering or a related field.
Once you have completed your training, you will need to obtain a journeyman's license if your state requires it. After gaining some experience, you may also choose to become certified by the National Institute for Metalworking Skills (NIMS).
Lathe machinists must be able to read and interpret engineering drawings and blueprints. They must also be familiar with the different types of metals and their properties. Strong math skills are essential, as machinists must be able to calculate dimensions and tolerances.
Operating a lathe requires manual dexterity and a steady hand. Machinists must be able to work quickly and efficiently while maintaining accuracy. They must also be able to use precision measuring instruments such as calipers and micrometers.
Safety is important in any manufacturing environment, and lathe machinists must follow safety protocols to protect themselves and those around them. Common hazards include flying debris, noise exposure, and injuries from moving parts.
