What is CNC machining or computer numerical control?
Computer numerical control is an automated system for running machining processes. It is more efficient and faster than manual control. It can perform machining tasks with greater precision, including cutting, welding, grinding, and stamping. It has the upper hand in manual processing and eliminates its limitations.
There is no on-site operator in the CNC process to prompt and guide tools such as levers, buttons, and wheels. CNC systems are like an arrangement of computer components. But its functionality is in sharp contrast to other types of computing. It has special software programs and consoles for effects and performance.
The history of CNC machining services
The history of CNC machine tools began in 1940 with the introduction of the electric motor. Motors are used to replicate preexisting machine tools. With the development of technology and the introduction of computers, the mechanism has become more advanced. Analog computers were used for this purpose. Digital computers now control all processes. All of these innovations led to its appearance on CNC machines.
Today, we have electronic CNC machines that work on different mechanical systems. CNC machines come in different variants, types, and forms and perform complex ultrasonic welding and laser cutting processes.

Why choose CNC machining services?
In today’s industrial environment, the manufacturing process relies on CNC machining tools. Different operations are performed through automated processes, and CNC machines operate various types of equipment. Manufacturers have replaced the equipment needed by operators with CNC machining tools. We can produce suitable and precise industrial products more accurately using CNC tools.
CNC machining tools provide us with financial and manufacturing advantages over traditional machining. It helps if you have a skilled professional on each machine in the traditional way, but CNC machines make it possible to operate multiple machines with just one technician. For example, in a traditional machining shop, each machine must have a skilled technician, while in CNC machining, one professional can operate multiple machines.
CNC milling services are one of the most commonly used machining methods in machining. It is mainly used for face milling and contour milling and drilling, extending, reaming, boring, and tapping parts. Parts suitable for NUMERICAL control include:
(1) Plane parts
Each machined surface characterizes planar parts that may be planar or planar. At present, most parts processed in CNC milling services are plane parts. Flattening parts are the simplest kind of CNC machining objects, which can usually be processed by two-axis linkage machining of a three-axis CNC milling machine (that is, two-axis semi-coordinate machining).
A plane part with a plane profile, a plane part with an inclined plane has a positive plane part, and a rib plane part.
(2) Variable tilt parts
Apart from a constantly changing Angle between the machined surface and the horizontal plane is called a variable Angle part. When machining variable incline parts, it is best to use a four or five-axis CNC milling machine for Angle machining. Without such a machine tool, 2-axis semi-control line machining can approximate a 3-axis CNC milling machine, but with slightly lower Accuracy.
(3) Surface (3D) parts
The part whose machined surface is the space surface is called the curved part. The curved part is always in point contact with the machining surface of the milling cutter. Usually, three-axis CNC milling services machine processing, a commonly used processing method, have two kinds:
A. Two axes semi-linkage wire cutting method. The tangent method connects only two coordinates in the process of machining, and the other coordinates are carried out periodically with a certain line spacing. This method is usually used to deal with less complex surfaces of space.
B. Three-axis linkage processing. The CNC milling machine used must have X, Y, Z three-axis linkage machining function to carry out spatial linear interpolation. This method is often used to deal with more complex spatial surfaces such as engines or molds.
CNC machining produces many metal and plastic products used in various sectors in manufacturing. Many industries use CNC machines for accurate, consistent, and precise cutting. The following is an overview of the industry using CNC machining tools:
Aviation and transportation.
Agricultural application machines.
Medical services.
Electronic accessories.
Construction and manufacturing.
Metal products and raw materials.
Military industry and maritime industry.
Comparison between CNC machining services and traditional machining
CNC machining does have the upper hand over traditional methods, but both have the same goal. Both aim to cut raw metal or plastic into different pieces and shapes and turn it into a finished product. The difference lies in the automation of CNC machine tools and the manual method of traditional methods.
There are some key advantages to CNC machining, including:
speed.
Productivity.
Accuracy and Accuracy.
In CNC machining aluminum process, The programmers use software to cut the parts of a product. Meanwhile, in the traditional method, professional workers work on machines to cut metal pieces. The operator needs to use all tools, including gears, which are not used in CNC machining tools.
We can use traditional methods to save costs and small batch projects. If you need mass production, CNC machining is the best choice. Traditional machines require different tools, which are also used in CNC machines.
