Guide to CNC Machining Basics
With the continuous development of society, traditional manual processing has been difficult to keep up with supply and demand. Therefore, the emergence of CNC machining is undoubtedly a huge change, especially in the field of manufacturing, where both light and heavy manufacturing play a vital role. This guide is definitely a treasure for engineers who want to learn CNC machining or designers looking for CNC machining services. The content of this guide mainly introduces the introductory knowledge of CNC machining, covers the relevant content of current CNC machining, and introduces the origin, manufacturing process, and future development and application of CNC machining.
What is CNC machining?
If described in terms of kinematics, CNC machining is to input CNC programming on the computer, the NC center system sends instructions to the CNC lathe, and the CNC lathe manipulates the CNC tool to complete the machining process on the material. From the perspective of processing technology, CNC machining can be regarded as digital manufacturing technology, subtractive manufacturing technology, or multifunctional manufacturing technology. But whichever description is correct, this is an efficient, automated, modern processing technology today. Nowadays, almost all parts in all walks of life come from CNC machining.
Working Principle of CNC Machining
Today’s CNC machining programs mainly rely on G codes, which control the corresponding tools to precisely cut different materials and form customized parts.
What Does CNC Stand For?
1. Opportunity: In today’s extremely competitive era, as long as you seize the market first, you will be a big step ahead of others. CNC will shorten the processing cycle of parts, helping you to occupy the market share first in time and cost.
2. Professional: Due to the different CNC machine tools, improper operation will cause existing safety hazards, such as sharp edges, moving parts, sparks, hot surfaces, chips and noise problems, burns, fractures, cuts, abrasions, hearing loss, and dangerous eye damage, etc. This is also our original intention to provide CNC machining services, we have professional CNC operators to avoid this from happening.
3. Cost saving: As we mentioned earlier, CNC is a versatile, high-precision process that can process materials of various complex shapes and produce high-volume parts. But before the design drawings come out, the consumption rate of these materials is relatively high, and the traditional processing methods cannot maximize the cost-effectiveness of the materials. If an individual purchases a CNC machine tool for processing, the intermediate process seems simple, but in fact, it is not as good as directly enjoying the CNC machining service, because the subsequent repair and maintenance costs are relatively expensive.
A Brief History of CNC Machining
When it comes to the development of CNC machining, it is inseparable from James Parsons. The original idea of this gentleman was to produce better helicopter blades or other parts through CNC machining. Make the aircraft performance more stable and safe. So there was the first CNC machine tool because the production of this machine tool had a great influence on later generations. In the fifth year after him, that is, in 1952, researchers from the Massachusetts Institute of Technology developed the first CNC machine tool. The CNC machine tool also applied for a patent in 1958, so in order to praise Parsons, people praised him as the father of CNC machining. It was from 1972 to 1976 that CNC really started to announce that it entered the popular stage. At this stage, CNC machining had obviously achieved significant development, which improved the processing accuracy at that time. By 1989, the parts produced by these CNC machine tools had become the processing industry standard.
CNC Machining Machine Type
Due to the diversification of social industries, a single processing machine tool can no longer meet the needs of the social development process, so processing machine tools that meet various processing parts were born. These machines can target complex, high-precision, and small-batch CNC-machined parts. There are many types of CNC machine tools used for processing and production. The following are several common CNC machine tools.
According to the function and type of processed parts, CNC machine tools can be divided into five main processing machine tools: CNC milling machines, CNC lathes, CNC drilling machines, CNC plasma cutting machines, and CNC grinding machines.
CNC milling machine: It has a contour motion system, and is generally divided into vertical CNC milling machine, horizontal CNC milling machine, and gantry CNC milling machine according to the characteristics of the spindle. It allows the machine tool to cut the corresponding raw materials according to the code program input by the CNC programming and has a continuous processing path. It is often used in the process of manufacturing CNC milling parts and can complete the processing of particularly complex parts, such as mold parts and shells. The process of manufacturing parts on a CNC milling machine is usually called CNC milling, which is a subtractive manufacturing process. Processing features: the material is rotated, the position of the tool is fixed, and parts such as grooves, planes, tooth surfaces, helical surfaces, outer circles, and formed surfaces can be processed.
CNC lathe: equipped with tool magazine, CNC machining center with automatic tool change function, capable of performing various cutting operations, such as cutting, turning, drilling, undercutting, end face processing, boring, and knurling, is a highly automated machine tool product. The processing technology carried out on the lathe is generally called turning, which is often used to process cylindrical materials. Processing characteristics: the material is fixed, and the tool rotates.
CNC Drilling Machine: Used for drilling, CNC tools can accurately and quickly determine the position of the drilled hole.
CNC plasma cutting machine: It uses an accelerated hot plasma jet to cut conductive materials, often used to cut metal.
CNC Grinding Machine: A machine that usually uses a rotating wheel to grind raw materials to make the machined parts required for the design. Compared with milling machines and lathes, its CNC programming is easier.
By Bearing
In the CNC machining service industry, there are many machine tools used for machining, which can be distinguished according to the different linkage axes
1. Two-axis linkage: it often appears on the processing rotating surface of the CNC lathe or the processing curve cylinder of the CNC milling machine.
2. Two-axis semi-linkage. During the machining of the part, two of the axes can be linked and the other can be periodically replenished. It cannot be linked all the time, so it is called two-axis semi-linkage.
Nowadays, two-axis linkage and two-axis semi-linkage have gradually withdrawn from the field of vision of CNC machining services, replaced by the following three common machining axis linkages.
3. Three-axis machining is generally divided into two types. One is that the three-axis machine tool uses a fixed tool to perform simultaneous cutting along three coordinate axes: X (from left to right), Y (from front to back), and Z (from top to bottom), such as the milling machine CNC. The other is to control the two linear coordinates of X/Y/Z at the same time, and also control the rotation coordinate axis that rotates around one of the linear coordinate axes. For example, a turning machining center, in addition to the vertical (Z-axis) and horizontal (X-axis) two linear coordinate axes, also needs to control the spindle (C-axis) rotating around the Z-axis at the same time.
4. Multi-axis linkage processing: When the CNC machine tool simultaneously controls the X/Y/Z three linear coordinate axes and a certain rotation axis linkage or simultaneously controls the X/Y/Z three linear coordinate axes linkage (four-axis machining) ability. It can also simultaneously control two of the A, B, and C coordinate axes to rotate around these linear coordinate axes, forming simultaneous control of the five-axis linkage. At this time, the tool can be positioned in any direction in space (five-axis machining), which is called a multi-axis CNC machine tool.
Multi-axis CNC machining can also be understood as 3+2-axis indexing CNC machining, which refers to the movement process in which 5 linkage axes move along 3 linear axes, and the machine bed and cutter head can also rotate at the same time.
3-Axis CNC Machines VS Multi-Axis CNC Machines
3 axis:
1. Easier to program
2. Manual repositioning of machined parts is required
3. Hindered by part geometry
4. Increase CNC machining operations, which may reduce the accuracy of the process
Multi-axis:
1. Complicated programming
2. No need for human intervention
3. Reduce manual steps
4. Save processing time
5. Not hindered by part geometry
6. Added cost of specialized machinery and more specialized programmers and operators.
Advantages of CNC Machining
Short production cycle
CNC automation saves a lot of time and operating costs. It is more prominent in rapid prototyping, the start-up cost is relatively low, and it can frequently create CNC parts for you.
Tight tolerances
The parts processed by CNC have strict high precision, which is more accurate than the prototype manufactured by mold processing, which means that the data you can get when using parts for functional testing is more accurate. And precision CNC machining services can even control tolerances below 0.0002 inches. Compared with manual processing, the accuracy and precision are higher, which can produce high-quality products.
Wide range of materials
CNC-machined parts have excellent physical properties. In daily life, almost all common high-hardness materials can be CNC machined. You can choose the material you want for testing.
Production on demand
CNC machining parts can provide on-demand production services, reducing the impact of parts inventory backlog and slow sales due to overproduction of parts.
Excellent repeatability
CNC machining has excellent repeatability, which is very suitable for small batch and large batch production requirements, and improves the batch production efficiency of various industries.
Complex parts production
CNC machining can process hard metal and alloy materials that are difficult to process by manual methods, as well as complex 3D shapes.
How to Choose The Right CNC Machining Service?
If you have read the above content, you will find that when choosing a part manufacturing process, you should first evaluate which type of processing is more suitable for this part, whether it is three-axis processing or five-axis processing. In general, 3-axis machines are more suitable for manufacturing parts with simple designs and fast and economical machining, while 5-axis machines are suitable for parts with higher precision and more complex geometries. The time cost in the middle will be relatively large. If you choose CNC machining services, professional engineers will give you advice and help you make the right choice quickly.
Generally speaking, 3-axis machining has a shorter setup time and simple programming and is the best choice if you are on a budget or just need to cut the material to obtain a flat surface. If you need the ability to manufacture parts faster, with higher precision, and with more complex geometries, then five-axis machining is the solution.

CNC Surface Treatment and Finishing
Generally speaking, the parts processed by the CNC center are relatively original, and the machined parts without any surface treatment will have some lack of aesthetics. Therefore, some finishing processes are required to improve the appearance of parts, reduce the effect of parts defects, improve the precision and wear resistance of parts, etc.
Anodized (Aluminum) (Type II or Type III)
Anodizing aluminum is a process of electrolytic oxidation. Through the action of the external current, an oxide film is formed on the surface of aluminum products. In this process, aluminum or aluminum alloy is generally used as the anode, and zinc as the cathode. Anodizing is an important part of aluminum alloy surface treatment. Oxidized parts can prolong the service life and expand the scope of use. It has a good protective and decorative effect.
Polishing
Polishing refers to the process of using polishing tools to trim parts and reduce the roughness of machined parts to obtain smoother and flatter CNC machined parts. This process will not improve the precision of the part, but it will beautify the surface of the part.
Black oxidation
Black Oxide is a conversion coating that improves the appearance of metals. It is often used on steel, stainless steel, copper, and other metal parts that are easily exposed to air and cause rust. The process of dealing with this process is also called blackening treatment. The metal parts treated by this process have strong anti-rust ability and improve the aesthetics of the processed parts. This process is often used in CNC machining.
Sandblasting
Sandblasting is a process for machining parts. It uses a high-speed jet beam to spray the material onto the surface of the part to be processed, so as to achieve the purpose of rust removal, beautification, improvement of precision, and deburring. This is a fast and efficient process. Efficient surface preparation and clean machining methods.
Electroless Nickel

The process does not require electricity like electroplating. Electroless nickel-plated metal processing parts have good corrosion resistance, rust resistance, etc. Suitable for nickel plating on all metal surfaces.
Passivation
Through the principle of oxidation, the chemical process that makes the active metal surface into a state that is not easily oxidized reduces its surface activity and slows down the corrosion rate of the metal is called passivation. The formed passivation film is relatively complete, which can provide a protective oxidation environment for the processed metal parts and improve the corrosion resistance of the processed parts.
Powder coating
Powder coating, also known as the powder coating process, is a high-quality process to improve the corrosion resistance of machined parts. The process can use air as a transport medium and is a solvent-free process. Low energy consumption, 100% film formation of processed parts. The parts processed by this process are more beautiful.
