What are the different types of CNC machines?

In a CNC machining shop, there are several types of CNC machines commonly used, including CNC mills, CNC turning machines (or lathes), CNC routers, Electrical Discharge Machining (EDM) machines, and CNC grinding machines.

CNC mills utilize rotating cutting tools that are positioned at different areas of the workpiece to perform cuts. They are versatile and can be used to manufacture a wide range of parts.

CNC lathes, on the other hand, rotate the workpiece against a stationary cutting tool. They are mainly employed for producing cylindrical parts.

Swiss machines are similar to CNC lathes but differ in the movement of cutting tools. Instead of moving the tools, Swiss machines move the workpieces, allowing the production of small diameter round parts without deformation.

CNC routers are similar to CNC mills but generally have less power and are not suitable for cutting the hardest materials. However, they can operate at higher speeds compared to CNC mills.

EDM machines use electrical discharges (sparks) instead of sharp cutting tools to cut material. This process does not involve physical contact between the tool and the workpiece.

CNC machines are often characterized by the number of axes they possess. Machines with more axes can move their tools and/or workpieces in a greater variety of ways, providing enhanced cutting flexibility and the ability to create more complex parts in a shorter timeframe.

How Does CNC Machining Work?

The CNC machining process begins with the use of a computer and CAD (Computer-Aided Design) software, where designers create a part. Subsequently, the programmer utilizes CAM (Computer-Aided Manufacturing) software, such as HyperMill, PowerMill, Maxcam, or UG, to generate tool paths and obtain the NC files required for manufacturing the parts on mills, lathes, or other machines.

The instructions for the CNC machine are transmitted in the form of "G-Code," which the machine can read and execute. Most CNC machines incorporate a worktable and a work holding device to secure the workpiece, which is typically a block of material. Depending on the machine's configuration, the worktable may or may not move.

Once machining commences, the cutting tool comes into contact with the workpiece, removing layers of material. The tool and/or workpiece are moved and/or rapidly rotated based on the instructions in the G-Code. This precise movement ensures that cuts are made in the correct locations until the part is completed.

Advantages of CNC
machining

Here are some of the key advantages of CNC machining compared to other manufacturing processes such as 3D printing, injection molding, urethane casting, laser cutting, plasma cutting, or other sheet metal fabrication processes:

Cost-efficiency:

CNC machining can be cost-efficient for certain types of parts, particularly when the part geometry is simple and requires minimal raw material removal. The high-speed capabilities of CNC machines allow for quick material removal, resulting in lower unit prices compared to 3D printing, which can be time-consuming for such parts.

Precision:

CNC machining offers high precision with machine tolerances typically reaching +/-0.005 mm. This level of precision allows for parts to be machined with tolerances as tight as +/-0.01 mm. In contrast, 3D printing processes, which build parts layer by layer, often have minimum layer heights of 0.05 mm, limiting the achievable tolerances.

Surface finishing:

CNC machining can achieve excellent surface finishes, reducing the need for extensive post-processing. With high spindle speeds and precise cutting tools, CNC machined parts can have surface roughness below Ra 0.8, suitable for bead blasting, painting, or anodizing without manual sanding. In comparison, parts produced through processes like SLS, SLM, or DMLS often have higher surface roughness (Ra > 3.2).

Flexible part sizes:

CNC machining offers flexibility in part sizes. Large CNC machine centers can accommodate tables measuring 6 m x 30 m or larger, enabling the milling of very large parts. Conversely, with precise 5-axis CNC mills and small cutting tools, intricate geometries can be milled from tiny blocks as small as 1 mm x 1 mm x 1 mm. Swiss machines are also suitable for manufacturing small parts for medical applications. Other processes like 3D printing, urethane casting, die casting, and injection molding have limitations in achieving extreme minimum and maximum part sizes.

Overall, CNC machining stands out for its cost-efficiency, precision, surface finishing capabilities, and flexibility in part sizes, making it a preferred choice for various manufacturing applications compared to alternative processes.
