Today we will focus on how our milling machine SZGH-650 achieves milling and drilling?
By understanding their unique features, we can help you choose the right processing method.

What is CNC milling and drilling?
CNC drilling is another subtractive manufacturing method that focuses on creating precise holes in the workpiece according to the uploaded CAD design. It usually involves single-axis motion. The drilling machine utilizes a computer-controlled rotating drill to drill holes. At the same time, the drill size is exactly or slightly smaller than the required hole diameter.

Unlike other operations, the CNC drilling process is specialized for drilling holes for different applications. With the corresponding drill, you can process straight holes, center holes, tapped holes, reamed holes, and other types of holes.

In addition, there may be two different workpiece movements in CNC milling. In the first, the workpiece moves in the same direction as the tool rotation, which is called down milling or reverse milling. In the second case, the tool rotates against the feed direction, which is called conventional milling or down milling.

These two functions can usually be used in the following industries:
Applications of CNC milling:
Automotive parts such as cylinder heads, engine blocks, transmission housings, etc.
Prototype design in various industries
Components and implants for medical devices
Mold and tool manufacturing
CNC milling is preferred over drilling because it can machine detailed geometries. Still, drilling is essential when precise cylindrical features are required.

Applications of CNC Drilling
Deep and small holes in a variety of materials.
Drilling holes for fasteners on aircraft fuselages and engines.
Automotive assembly.
Precise and consistent holes in electronic boards to place components.
