What Are Some Major Varieties of CNC Machining Processes?

CNC (Computer Numerical Control) machining processes have revolutionized manufacturing, enabling the production of intricate and precise components across various industries. These processes utilize computerized controls to automate the machining operations resulting in high-quality, consistent, and efficient production.

CNC machining processes offer exceptional precision and accuracy, ensuring tight tolerances and high-quality components. Different CNC processes can handle a variety of materials, including metals, plastics, composites, and ceramics. CNC machining processes are highly automated, leading to increased productivity, reduced labor costs, and minimized material wastage.

CNC machines can replicate components with consistent quality, making them suitable for large-scale production and maintaining uniformity across batches. You can visit now this link to get details of CNC machining.

Types of CNC Machining Process

Here are some different types of CNC machining processes, each tailored for specific tasks and materials:

CNC Milling

CNC milling is a versatile machining process that uses rotary cutting tools to remove material from a workpiece. During milling, the workpiece is securely fixed to the machine’s worktable, and the cutting tool, typically a rotating end mill, removes material in multiple axes. CNC milling machines can create a wide range of shapes, slots, holes, and complex features. CNC milling is widely used in industries such as aerospace, automotive, and prototyping for producing components with precise dimensions and intricate geometries.

CNC Turning

CNC turning, also known as CNC lathing, is employed for cylindrical machining operations. In this process, the workpiece is rotated while a cutting tool removes material to create symmetrical parts. CNC lathes are ideal for producing components with circular or tapered shapes, including shafts, bolts, and fittings. They can work with materials like metal, plastic, and wood. CNC turning is essential for industries requiring high-volume production of cylindrical components due to its speed and efficiency.

CNC Drilling

CNC drilling machines are specialized for creating holes in workpieces with precision and accuracy. These machines use rotating drill bits to remove material and produce holes of various sizes and depths. CNC drilling is crucial for applications requiring precise whole positioning and dimensions, such as aerospace, electronics, and automotive manufacturing. It is commonly used for materials like metal, plastic, and composites.

CNC Electrical Discharge Machining (EDM)

CNC EDM is a non-traditional machining process that uses electrical discharges to remove material from the workpiece. EDM is highly effective for machining intricate and complex shapes in hard and conductive materials, including metal alloys and hardened steel. CNC EDM machines offer high precision and can produce components with fine details and tight tolerances. This process is widely used in industries like aerospace, medical, and tool manufacturing for producing molds, dies, and delicate components.


A workpiece can be shaped into a crevice via broaching, which uses a cutting head with teeth. Broaching cuts exhibit remarkable accuracy and consistency. These devices can be either rotary (using a toothed cutting tool that rotates) or linear.

CNC Lathes

The main shaping tools for cutting wood or metal are CNC lathes. The machining head in a lathe machine travels linearly along the surface while the workpiece is rotated around a central axis. CNC lathes are capable of a wide range of operations, including drilling, sanding, knurling, facing, and more. In terms of performance, CNC lathes outperform manual lathes.

Plasma Cutters

A high-temperature plasma jet is used by plasma cutters, an advanced cutting technology, to cut material. Since an electrical arc produces the plasma, this technique is limited to conductive materials.

Bottom Line

Each kind of CNC machine has its own set of instructions for use. In general, CNC machines are simple to use and don’t require technical training to be completed by the user. After watching a few hours of the many available online tutorial videos, you can actually make fundamental parts. Once you understand how to write effective digital programming code and produce technical drawings, you can use a CNC machine to optimize the current manufacturing process.
