CNC machining-i.e., computer numerical control machining—is a broad term referring to the subtractive manufacturing processes used to create precision parts and components. As implied by the name, these processes employ the use of computer-guided machining tools to remove—i.e., machine—excess material from a workpiece to achieve the desired shape and size.

All CNC machining operations begin with a CAD model of the part. A CAM program reads this generated file and converts it into a series of coded instructions that the machining equipment can follow. A key benefit of using these processes is that, once the file is approved, very little—if any—human intervention is necessary. Instead, the computerized controls monitor and guide the movements of the machine, minimizing the potential for error and allowing for extremely consistent results.

At Associated Fastening Products, our team is well-versed in CNC machining. We perform various computer-controlled machining operations to manufacture a wide range of standard and custom fasteners for our customers. We’ve put together the following overview to help customers fully understand the process. It outlines the types of machining operations available, general advantages of the process, typical materials used and products created, and industrial applications.

Types Of CNC Machining Operations

Within the broader category of CNC machining, many different machining operations can be used to craft the final component. Three of the most common are:

Advantages of CNC Machining

Compared to traditional manufacturing methods, CNC machining offers several benefits, including in regard to the production of standard and custom fasteners. The following represent some of the most significant reasons to employ the process:

Greater Precision and Accuracy

CNC machines allow for the replication of the same component thousands of times over, with each piece produced having the same dimensions as the previous. Additionally, the computerized controls enable industry professionals to achieve a higher level of precision than is generally possible with manual machining methods.

Faster Turnaround

The CNC machining process also carries the potential for substantial time savings. With traditional machining equipment, operators must manually configure and set up the machine for each operation. In contrast, CNC machining equipment can make the necessary changes by a simple adjustment in the computer code. Additionally, while humans need breaks, these machines can operate consistently for more extended periods, allowing them to fulfill orders in a shorter time period.

Better Scalability

CNC machining is suitable for both prototyping and production runs. As the process does not require intensive machine and tool preparation—instead using a CAD file—it’s possible to quickly and accurately produce a prototype. Once a part design is approved, it can then proceed to full-scale production.

Broader Versatility

CNC machining operations accommodate a wide range of designs in metal, polymer, and other materials. This versatility makes them suitable for the manufacture of numerous different parts and products.

Types Of CNC Machined Components

Industry professionals across a diverse set of industrial sectors employ CNC machining processes to produce the various parts and products they need for their operations. Within the fastener sector, some of the typical products manufactured include:







Materials Used In CNC Machining Operations

As indicated above, CNC machining accommodates a variety of materials. While the choice of material depends on the part design and intended application, some of the most commonly used include:







For fasteners, most machining operations utilize metals (e.g., aluminum, brass, carbon steel, copper, and stainless steel) or plastics (e.g., nylon).

Industries & Applications

As you might expect from such a versatile manufacturing technique, CNC machining finds application in a wide range of industries. In particular, it is ideal for industries that require highly precise and accurate components. For example,
