How deep can a CNC router cut?

If you haven’t worked with a CNC router before, you may certainly be wondering “How deep can a CNC router cut?” The answer to this question certainly depends on many factors. The kind of material to be cut, the accuracy of the CNC router, and the shape and size of the parts being machined all play a role. Nevertheless, industry professionals believe a CNC router can easily cut material that is up to 1 inch (2.5 cm) thick.

What is a CNC router?

A CNC router is an industrial machine that a computer controls. It has a cutting device that cuts or carves pieces out of metal, wood, plastic, and other materials. Routers can create shapes of all kinds, from simple designs to complex 3D molds. Finally, they can be used for woodworking projects, as well as more intricate jobs like making prototypes or models.


How deep can a CNC router cut?

Depending on the size of the bit and the cutting speed, a CNC router can certainly cut through a variety of materials. The cutting depth is limited only by the bit length and the precision with which it is programmed. In most cases, a bit size of 1/4 inch or less will result in a cut that is deep enough. While larger bits create deeper cuts; they can cause more damage to the material they’re cutting. A CNC router can only make a straight cut, whereas a series of straight cuts will result in a curved shape.


Types of CNC routers

CNC routers fall into three categories: the fixed bed, the moving table, and the hybrid. A fixed bed router specifically has a stationary workpiece where the tool head moves along the x and y axes. The moving table router moves the whole workpiece along the x and y axes. Thus a hybrid router combines a movable workpiece that is attached to a stationary table.

The moving table router is the most common type of CNC router. It’s ideal for larger projects because of the accuracy and stability. Fixed bed routers are great for small projects because they’re more compact and can fit into small spaces. The hybrid router is versatile and can handle both large and small projects.

Be sure to select a CNC router that will meet your project needs.


Advantages of using a CNC router

Most workshops can benefit from having a CNC router. There are several advantages to operating one:

  1. The CNC router delivers a high level of accuracy and precision. For projects that require fine detail, it’s a perfect choice.
  2. The CNC router is highly efficient. This makes it easy to make intricate patterns or designs quickly.
  3. The CNC router can be used for an array of jobs. Some of these are sign-making, woodworking, and metalworking.
  4. The CNC router is simple to use. Someone who’s never used one can execute a project efficiently and easily.
  5. CNC routers are economical. For people or companies who are looking for a dependable, precise machine tool, it’s an affordable option.



To conclude, CNC routers can cut a variety of materials with precision. The size of the router bit dictates the depth of the cut, the speed of the router’s movement, and the total applied pressure. It’s possible, even without experience, to learn to operate a CNC router to make intricate and beautiful patterns.
