Frequently Asked Questions About The CNC Milling Service

by Tracy Ehighalua

CNC milling services are pretty trendy. Their trendiness is attributed to the essential nature of the services they offer. The milling service is used in almost all sensitive sectors of the economy. For example, in the automotive industry, CNC milling services are used to produce gears. The gears are usually produced precisely. Thus, the precise nature of the parts produced makes them quite popular. Its popularity has sought many to learn more of the service. Below are some frequently asked questions about the CNC milling service.

Frequently asked questions about the CNC milling service

1. What is the definition of CNC milling?

CNC milling can be defined as a subtractive method of manufacturing where a workpiece is processed via computer controls. The milling process involves the multi-point cutting tools rotating to take out material from the raw material continuously. In short, CNC milling is an automated machinery process that assists manufacturers in obtaining custom-ordered parts.

2. What are the different types of milling machines?

There are two primary types of milling machines available in the market. The two types include; horizontal milling machines and vertical milling machines. The horizontal milling machine consists of cutters that are positioned on a horizontal arbor. It has a rotary table, also commonly known as a universal table, that assists the milling process in several angles.

The vertical milling machine consists of a vertical spindle axis. It rotates by staying in the same position. Additionally, the spindle can perform functions like cutting and drilling. The main difference between the two is that the horizontal milling machine has a universal table.

3. How many axes can a CNC milling machine operate?

Axes are crucial in developing precision. Therefore, the majority of the CNC milling machine uses three to five axes to function well.

4. What type of service does CNC milling offer?

CNC milling can manufacture low and high volumes parts. Additionally, it uses subtractive techniques to achieve complex and simple parts. The milling machine uses a cylindrical tool to remove pieces of raw material.

5. What are the various milling operations available?

The milling operations are not a standard operation. Instead, there are several other milling procedures. The different types of approaches have different complexity levels. The various processes include; slot milling, gang milling, side milling, up and down milling, straddle milling, face milling, form milling, and turret milling.

6. How does the CNC milling process work?

CNC milling machine works by following coded instructions. The coded instructions direct the machines on the type of operation is required. Thus, the machining process replicates every instruction by following the CAD design, ensuring high efficiency and accuracy levels.

7. Is CNC milling complex?

The intricacy of the CNC milling process depends on the part design. For simple designs, the process will be simple. But, for complex designs, the processes involved will also be complex. 


CNC milling is a vital part of the world’s smooth operation today. It is used in the development of parts for the most critical sectors. Therefore, if you wish to know more about CNC milling, the above is just the first few steps.
