What Are the Types of CNC Machining Equipment

CNC Precision machining does not rely on a single type of CNC machine.  CNC machines themselves require different equipment and processes to use the parts in high-functioning applications.

Learning about the several precision machine types will help with knowing about their working and functionality.

Milling Equipment

Milling Equipment

The CNC milling has rotatory cutters from one direction to the other for the desired material. These rotatory cutters use CAM and CAD to manufacture the workpieces exponentially.

There are multiple meals included in CNC milling equipment. Some of these meals include helical Mills and end mills.

Milling machines have the capacity to ensure the manufacturing of different geometrical shapes. Some of these shapes are: Face-milled or peripheral-milled.

Flat surfaces with shallow cavities fall under the face-milled features. In comparison, surfaces with deep cavities belong to the peripheral milled features.

Turning Equipment

Turning Equipment

The working mechanism of CNC turning equipment differs from CNC milling machines. The tools of CNC turning equipment remain fixed in their place while the material is rotated.

The means for cutting the material are kept in a linear motion around the material to align the process of cutting effectively.

These machines can create deeper interior features and exterior details, making them very useful for manufacturing complex parts with additional information.

Drilling Equipment

Drilling Equipment

In some CNC machines, drilling equipment moves their drills in rotator motions, producing customer-oriented products. These drills are designed professionally, not letting the chips come in the way of the workpiece, ultimately giving out perfect holes.

The drilling equipment contains improved and multiple holes creating capacity. Thus materials get accurate holes without disturbing their structure.

Drilling equipment further contains exponential functions depending on the particular bits the manufacturer uses.

The range of bits used includes peck drills, which help reduce the chip count when making a product, and chucking drills, used for maturing the already-created holes of the defined parts.

CNC Electric Discharge Mining Equipment

Using a combination of the tooling electrode and the electrode of the piece on which work is being done, the EDM utilizes electricity sparks to get the desired results.

The electrodes must have a connection yet separation from each other, and it’s only possible with the dielectric fluid. This process is also referred to as spark machining or spark eroding.

There are different types of parts manufactured with CNC machines. The specific CNC machine a manufacturer selects depends on a particular part’s shape, function, and complex nature.

For example, if a manufacturer needs to make a cylindrical part, he can use a CNC lathe machine.

What are Main Applications for CNC Precision Machines?
