What’s the difference between a CNC Milling Machine and a CNC Router?
When it comes to CNC machining, there are two main types of machines: routers and mills. Each has unique benefits and drawbacks, making it the better choice for specific projects.
This guide will take a closer look at both types of machines and help you decide which is the best option for your next CNC machining project.
What Is a CNC Router, and What Does It Do?
A CNC router is a machine that uses a rotating tool to cut or engrave materials like wood, plastic, or metal. The device is typically a bit like a drill but with a spiral flute that helps remove the material as it cuts.
CNC routers usually have a larger cutting area than mills, making them better suited for larger projects. They’re also generally faster than mills, making them a good choice for plywood work.
The CNC Router and Its Workspace
CNC routers typically have three axes: x, y, and z. The x-axis runs left to right, the y-axis runs front to back, and the z-axis runs up and down. This allows the router to move the tool in all directions relative to the workpiece.
A typical CNC router setup is made up of a large stationary bed that the workpiece can be secured to. The cutting tools are held within a spindle that is mounted to a gantry system that is controlled with the use of a computer.
Why Should You Get a CNC Machine?
CNC routers are fast, accurate, and versatile machines that handle various materials. They’re ideal for precision work and are especially well-suited for projects that require intricate details or tight tolerances.
What Is a CNC Mill, and how Does it Work?
A CNC mill is a machine that uses a rotating tool to cut or engrave materials like wood, plastic, or metal. The device is typically a bit like a drill but with a spiral flute that helps remove the material as it cuts.
Mills usually have a smaller cutting area than routers, making them better suited for smaller, mostly metal projects. They’re also slower than routers but more accurate, making them ideal for precision work.
The Difference Between a CNC Mill and Router
The primary difference between CNC mills and routers is their size: mills are smaller and can handle more precise projects, while routers are bigger and better suited for high output work.
Both machines can do the same things in terms of function: they can cut or engrave materials using various tools depending on the project requirements.
Materials for Creating Products
Routers and mills use different types of materials to create products. A router typically uses plywood or melamine, while a mill can use aluminium, brass, copper, steel, and other materials. The material you use will determine the mill or router you should use.
The Speed of the Machine
The speed at which a machine can produce parts is essential when choosing between a mill and a router. A mill can machine at a much faster speed than a router.
The Type of Component in the System
Another difference between mills and routers is the type of components each can produce. A mill is capable of creating much more intricate parts than a router. This is because a mill’s cutting area is much smaller than a router’s.
As a result, mills are often used for machining smaller parts with tight tolerances.
Precision
The accuracy of machines is also an important consideration when deciding whether to use a mill or router.
The Pros and Cons of CNC Machining
The primary advantage of CNC milling machines is that they can produce precise results due to their high accuracy and repeatability. Milling machines can also handle a wider variety of materials than routers, including tougher materials like stainless steel and titanium.
However, CNC milling machines are generally more expensive than routers, requiring more setup time and expertise. Routers are also better suited for making curved shapes and are much faster than mills when it comes to machining large quantities of parts.
