Because of the high demand for CNC machinery, the global market for CNC machinery is expected to reach $134 billion by 2030


Because of the high demand for CNC machinery, the global market for CNC machinery is expected to reach $134 billion by 2030. What is it about this product that has such a strong demand? Demand for CNC machinery is increasing exponentially because it is more time efficient and less prone to human error than conventional machinery (milling, turning, screw machining).

Aside from that, CNC machinery is extremely accurate; machinists typically measure deviation in terms of tolerance. Example: A +/- and then a millimeter measurement are typically used to indicate bilateral tolerance. Although some CNC machines have an even tighter tolerance than this, the standard tolerance for many is 0.005 inches (.000127 mm). While many of the items that we use on a daily basis have components that were created using CNC milling services, cnc turning services, or another CNC process, CNC machines are particularly useful when it comes to creating parts for industries where human lives are at risk. Thus, it should come as no surprise that the industries listed below rely on CNC machinery to manufacture a wide range of parts.

Firstly, the transportation industry

Long-lasting parts are required for automobiles, trucks, trains, and freight carriers. Vehicles that transport people and goods from one location to another are constructed from components such as pistons, sleeves, shafts, and couplings. Due to the high level of precision provided by CNC machining, the parts are manufactured with precise dimensions, thereby increasing their reliability and durability and increasing their longevity.

Prototyping and research are two other aspects that are critical to the transportation industry. To ensure that the prototype functions as intended, designers must be able to physically evaluate it in order to adapt the design for maximum safety. Prototyping components on a CNC machine reduces the amount of time that is required.

Secondly, the Aeronautical and Aviation Industry

In order for flying machines to be successful, engineers must take into consideration a variety of factors, including air currents, high pressure, and high speeds. It is critical that each component of an airplane, space shuttle, or rocket be manufactured to exacting specifications, or the lives of many people could be put in danger. To ensure compliance with regulations, tolerances for aeronautical parts are frequently required to be within 0.0001 inch.

Parts such as airfoils, spacers, blisks, housings, landing gear, and even space shuttle seats can be manufactured with computer numerical control machinery.

Aeronautical engineers, like their counterparts in the transportation industry, benefit greatly from the ability to prototype and test parts quickly. After testing has been completed, the CAD file can be easily modified and converted into a CAM file for use in the manufacturing process. The transition to mass production is simple when the part is perfect.

Industry of the Medical

The medical industry's reliance on customized parts for patients that are also disposable (in order to prevent cross-contamination between patients) makes CNC machinery an excellent solution. As a result, hospitals and other businesses in the medical industry are able to produce large volumes of customized parts quickly and efficiently, while maintaining high levels of precision.



A wide range of CNC machines (mills, lathes, drills, welding, and so on) are used to manufacture critical medical equipment such as implants, MRI machines, orthotic devices, and electronic enclosures for monitoring devices, to name a few examples. A person's life is saved every day as a result of the ability to craft these items with precise cuts.

Industry of the Energy

Machines that cut and shape metal have long been used in the energy sector, specifically the oil and gas industries, to manufacture parts for rigs and refineries. CNC machines have been used in this industry for many years. In particular, drilling rigs are at risk, and the components of machines must be precisely manufactured and accurate. Unlike aeronautical equipment, which must contend with challenges such as air currents, parts used in the water must be able to withstand the environments in which they are used. This holds true regardless of whether the oil well is located in the desert or the ocean. Both the salt from the ocean and the dust from the desert must be able to withstand the parts' exposure.

Additionally, many wind energy companies, in addition to the oil and gas industries, use CNC machines to fabricate turbine pieces and other components that help to harness natural energy sources.


The Military/Defense Sector

Company types, as well as the machines and parts required for the defense industry, are diverse. Because of the sensitive nature of the information involved, this industry is distinguished by the secrecy that surrounds the specific parts that are manufactured. The technology and equipment, on the other hand, must be up to date and current; cnc machining, with its efficiency, speed, and accuracy, makes it possible to accomplish this.

CNC milling, turning, and other operations are used in a variety of other industries, including consumer products and electronics. Neither traditional milling nor turning can compete in terms of precision and efficiency.
