What is a CNC boring mill and how does it work?


Only a few centuries ago, absolutely all the tools and objects used by man in his daily life were made by hand. Of course, this was long before the arrival of industries and ISO standards!

Today, highly sophisticated tools make it possible to produce parts and components with ever-increasing speed and precision from just about any material. The CNC boring mill is one such piece of equipment.

In this article, find out what a CNC boring machine is and how it works.

What does the abbreviation CNC stand for?

The CNC abbreviation stands for Computer Numerical Control. This technology, which involves the numerical control of a tool via a computer, is now used in a variety of machines and tools. These include, of course, CNC boring mills.

According to this definition, a CNC boring machine has to interact with a computer equipped with software that converts the numerical code into Cartesian coordinates. These coordinates will be the precise instructions that describe the movements to be carried out to automatically transform a virtual object into a real one. This enables the machine to work with a high degree of precision, just like a robot.

A CNC boring mill transforms raw material into a finished model by subtraction. The machine uses a cylindrical cutting tool that can rotate in different directions and move on several axes. It also has the ability to create a wide range of shapes, slots, holes and other cuts.

Different types of CNC boring machines

CNC boring machines are often grouped according to the number of axes on which they can work the material. For example, in the case of 4-axis CNC boring machines, each axis is identified by a specific letter. The X and Y axes represent the horizontal movement, the Z axis represents the vertical movement and the W axis represents the diagonal movement through the vertical plane.

The majority of CNC boring machines offer 3 to 5 axes. The most advanced CNC boring machines can produce specific shapes that are virtually impossible to achieve with manual techniques.

It is also worth mentioning that most CNC boring machines are equipped with a special device that sends lubricant to the cutting tool during the mechanical part machining process.

What types of materials do CNC milling cutters use?

Almost all types of materials that can physically be drilled or cut can be machined on a CNC boring mill. However, most machinists use CNC boring mills to work on metal materials.

As with drilling and cutting processes, the appropriate CNC machine tools must be selected for each material used. The density of the raw material as well as the rotation of the cutting tool must be taken into account before starting the precision machining process.

What do CNC milling cutters produce?

In general, CNC boring mills are very efficient for the prototyping and production of parts and various gears with complex shapes. They can also be useful for manufacturing custom parts or reproducing parts that have been damaged.
