Types of Metal CNC Machining

There are two main technologies of CNC machining: CNC Milling and CNC Turning.

CNC Milling is the most common and popular machine in CNC manufacturing. CNC Milling machines utilize rotary cutters to remove material from a part mounted on the machine bed. There are different types of CNC Milling systems, the most common type is 3-axis CNC machine. 3-aixs means the system has 3 linear degrees (the X, Y, Z axes) to produce parts. While the advanced one is 5-axis CNC machine, which owns 5 degrees of machining freedom and is suitable for creating parts with highly complex geometric geometries. Besides, 5-aixs CNC Machining is ideal for simplifying manufacturing steps.

CNC Turning, or we call CNC lathes remove material from workpiece mounted on rotary chucks by utilizing stationary cutting tools, which is an ideal solution to producing parts that are symmetrical about a central axis. Therefore, CNC lathes usually make cylindrical parts. But if CNC Turning systems equipped with CNC Milling tools, non-cylindrical parts can be manufactured as well. It can be a versatile solution for manufacturing. Combining high productivity and efficiency of CNC Turning with machining capabilities of CNC Milling, the system is being able to manufacture parts in a variety of geometries with rotational symmetry.

Metal CNC Machining Processes

Step1

G-code Files Preparation

Like 3D Printing needs slicer software to covert the STL file so that 3D printers can read and understand each layer data of the model, the first step for CNC Milling is to convert the CAD file into a language that the machine can work with, that's G-code.

Step2

Mount the Workpiece on the Fixtures

The operator will place the material that is cut to a specific size on the machine bed. Normally, the piece of the material is always called the blank or workpiece. Then it is time to mount the workpiece on the machined bed or by a vice.

Step3

Select the Right Cutting Tools

As the computer controls the CNC cutting tools to move to the pre-set coordinates, so precise positioning and alignment of the workpiece is significant to manufacture high-accuracy parts. Special metrology tools, probes, for instance, are ideal solutions for this step.

Step4

Cutting and Removing Materials from the Workpiece

Then, the workpiece is ready for machining. The machine uses professional cutting tools and rotating the at high speeds to remove material from the workpiece. However, at the very first steps, the machine removes at a relatively low speed and accuracy to gain an approximate geometry.

Step5

Flip the workpiece if necessary.

Sometimes, the model is not being to achieve full features by single setup from the cutting tools, to flip the workpiece is necessary.

Why Choose Metal CNC Machining?

wenext

CNC Machining produces parts with very tight tolerance, which means the technology can create parts with extreme high accuracy. The technology tends to create final parts with no defects, and the final parts can be used directly in applications.

wenext

Most materials of metal CNC machining have good mechanical properties, making the parts are high-quality and suitable for high-end applications, aerospace, engineering, and automobile, etc.

wenext

CNC Machining is the most cost-effective manufacturing process to produce metal parts from single prototypes to even up to hundreds of batch production.

wenext

CNC Machining needs less workers to operate as most of the process is automatically, which save personnel cost and enhance personnel safety.
