Wondering when to use a lathe vs mill? Whether you recently picked up a wood-turning hobby or run a metal shop in your community, you likely rely on a lathe or a mill to get the job done. These machines cut metal, wood, and plastic into desired shapes.
If you’re experiencing unexpected downtime and a decrease in productivity, it’s probably because your utility power supply isn’t providing the uninterrupted flow of electricity you need. Check out the guide below to learn more about how lathes and mills work and how a phase converter can benefit your projects.

What Is A Lathe?
A lathe is a machine that cuts materials like wood, metal, and plastic into desired shapes by spinning the workpiece in a circular motion at a high speed. The workpiece is secured with a spindle, which rotates it, and the cutting tool operates from a fixed position.
Types of Lathes
- Wood Lathe: A wood lathe is designed exclusively to cut and shape wood. It’s a manual machine, so the operator holds and guides the cutting tool.
- Metal Lathe: Although ideal for cutting metal, a metal lathe can also be used to cut wood and plastic. This machine operates automatically, with the tool post holding and guiding the cutting tool.
When to Use a Lathe
Lathes are ideal for cutting cylindrical and symmetrical workpieces. They also work well for jobs involving turning, like wood turning projects, which removes excess material from the perimeter or inside of a wooden workpiece.
Here are some additional lathe applications:
- Cutting
- Core facing
- Threading
- Boring
- Creating grooves, threads, and tapers
- Drilling center holes on turned pieces
What Is a Mill?
Like a lathe, a mill cuts and shapes metal and wooden materials. It does so by moving the workpiece along an axis that runs perpendicular to the spindle and against a cutting tool that rotates. First you have to determine what shape you want to make, mark reference points, and choose the right cutting tool for the job. Once put in place, the cutting tool removes excess material from the workpiece to create the shape.
Types of Milling Machines
When it comes to milling machines, you have various options to choose from based on your project specifications. Here are some of the most common types of milling machines:
- Knee and column milling machines
- Vertical
- Horizontal
- Universal
- Fixed bed/manufacturing milling machines
- Plano millers
- CNC milling machines
When to Use a Milling Machine
While a lathe is designed to cut and shape cylindrical or symmetrical workpieces, a mill is designed to shape flat and curved surfaces. Common applications include the following:
- Boring holes
- Cutting slots
- Shaping intricate part geometries
- Drilling
- Sanding
- Engraving
Lathe vs. Mill
Lathes and mills perform similar functions in different ways. They both remove material from a workpiece to create certain shapes and designs but have different ways of achieving this goal.
For example, the cutting tool on a lathe remains fixed while the workpiece rotates. On a mill, however, the workpiece is fixed and the cutting tool rotates. The cutting tool—also known as the spindle—can be raised and lowered to accommodate the size of the workpiece.
Why Power Supply Matters for Lathing and Milling
Most lathes and mills require a power source that can accommodate their high voltage. It’s important to consider how to power lathing and milling equipment because the power source directly impacts the equipment's efficiency, performance, and safety. Here’s how.
- Efficiency: The right power source ensures consistent operation, reducing downtime and increasing productivity, which maximizes profits.
- Safety: Proper power sources and electrical connections play a key role in preventing accidents and keeping operators safe.
- Cost: Selecting an appropriate power source can help manage operating costs and energy consumption, contributing to the overall profitability of the machining process.
- Reliability: A reliable power source ensures your equipment can perform its intended functions with minimal downtime and disruptions.
Using Three-Phase Power for Lathing and Milling
Three-phase power provides a more efficient and balanced electricity distribution compared to single-phase power. It consists of three alternating currents—called phases—that are 120 degrees out of phase with each other, creating a smoother and more constant flow of electricity. This balanced distribution reduces power fluctuations, making it ideal for powering heavy machinery like lathes and mills.
Single-phase to three-phase converters provide the high voltage and current needed to operate these machines reliably. By supplying a balanced power source, three-phase electricity ensures the equipment runs smoothly, efficiently, and with reduced vibrations, enhancing precision and performance in various applications.
Power Your Lathe or Mill the Right Way
The most important factor to consider in the mill vs. lathe debate is how to power your chosen equipment. Don’t rely on single-phase power from your utility line to get the job done. Invest in a digital or rotary phase converter to ensure consistent operation for reduced downtime and enhanced productivity. Our phase converters are made with the highest-quality materials and can be customized to fit your unique specifications.
