What is CNC Machining?

People only know the conventional way of machining. This process is effective and provided industries the products and components they need. Conventional machining is useful for many people even from way back. But, as time progresses, the needs of people and industries grow as well. This is when technology becomes an important factor in the change. With this, experts introduced CNC machining. Now, this became a popular choice for many industries and manufacturers.

CNC machining is a process where pre-programmed software dictates the manufacturing process. The instructions from the software command movements of the factory machinery and tools. This aims to control a wide range of machinery, from simple to complex. With the use of CNC machining, tasks can finish fast since there are lesser prompts to follow.

CNC stands for Computer Numerical Control. Its process helps speed up and improve what manual operations do. But, human operators will still operate the machines. CNC machining works by activating the CNC system. In the system, the desired cuts are already programmed. This allows the machines to move according to the prompts of the program. Following the prompts help create the desired end product. The CNC program stays in the computer memory. In case there are new designs and programs, computer programmers will have to add them in. The CNC machine operators should have knowledge on how the products should be. This way, they will know the way to run the machine according to the required output.

CNC machining is efficient, accurate, fast, and productive. It is still possible that errors may occur along the way. But it is still a more precise way to machine materials to produce an end product. This makes a worthy choice with manufacturing components and products.

CNC Electrical Discharge Machines

This machine is also called die sinking, spark eroding, or spark machining. It is because it uses electrical sparks to work on the materials. This works by giving off an electrical discharge to produce intense heat. With the heat, the material can melt or evaporate to create the desired design or shape. It is often used on hard metal. It can create micro holes and tapered or angled. This can also do slots and other complicated features.

CNC Plasma Cutting Machines

The CNC plasma cutting machines are also used for cutting. But instead of a laser, it uses a plasma torch. The computer controls this cutting tool to ensure accuracy. Like a laser, it melts the material according to the desired shape and design. It is important that the material used is conductive. A few examples of these are copper, brass, steel, stainless steel, and aluminum.

CNC machining offers a lot of functions and capabilities. It provides precise end products with improved speed and details. Industries and manufacturers use CNC machining for the best results.

Types of CNC Machining Operations

There are three basic types of operations that CNC machining can do. These are all necessary for creating the desired end product.


Drilling requires the use of multi-point drill bits. These can produce holes in the work piece. The rotating drill of the CNC machine works on the plane of the material’s surface. It works by creating aligned holes. This operation is useful in processes like countersinking, counter boring, tapping, and reaming.


Milling uses a multi-point cutting tool. The cutting tool, fed with the material, shapes the desired output. This operation can perform processes like cutting shallow and flat surfaces. It can also do deep slots and threads into the material.


This operation uses a rotating cutting tool. It works on the surface of the material to produce the desired circumference. CNC turning performs processes such as thread cutting, boring, facing, and grooving.
