A milling machine is an essential tool in woodworking and metalworking shops. These machines are widely used in metal-cutting applications in end-use sectors. The demand for fabricated metal products for both household and industrial purposes has steadfastly grown in the last few years. In 2020, the global milling machine market attained a value of $67.4 billion and is projected to reach $102.3 billion by 2026.
What is a Milling Machine?
Milling machines are widely used for the metal fabrication process. They do this by cutting and removing pieces of metal using a high-speed rotating cutter. Most milling machines can hold multiple cutters at a time. In comparison to other metal removal machines, the milling machines have high accuracy and better surface finishing.
There are approximately fifteen different types of milling machines and the most common is the vertical milling machine which is mostly used for slotting keyways, machining grooves, drilling, and boring holes. The CNC milling machine, also known as computer numerical control milling machines, are also popular. They come with computerized control and are typically faster than manual machines which makes them excellent for production work. They are also ideal for custom-design parts that require detail, precision, and a better surface finish.
Who Uses a Milling Machine?
The milling machine is widely used by machinists and woodworkers in metalworking and woodworking shops and modern manufacturing industries across the world.

What to Look for When Buying a Milling Machine
There are a couple of things that you need to consider when milling machine for sale, including:
- Speed: Speed directly influences the quality and overall finish of the processed part. Many high-quality machines provide higher RPM (rotation per minute) that results in a cleaner finish.
- Accuracy: Milling requires precision and accuracy. The best milling machines allow for tool positioning accuracy of up to 01mm.
- Table Size: Determines the size of parts that can be processed using the machine. Typically, the table dimensions range from 600X300mm all the way up to 6000X2500mm.
- Feed Type: Traditional milling machines used handwheels to move the workpiece to and from the drill. Today, modern milling machines require minimal to no physical labor. Computer Numerical Control or CNC milling machines is one of the most popular feed types. These machines use computer-controlled systems. The spindle in these machines moves in three directions and can even rotate up to 360 degrees.
