The Ministry of Trade, Industry and Energy (MOTIE) announced today that Korean company KCNC succeeded in localizing computerized numerical control (CNC) systems, which play an instrumental role in processing the majority of Korea’s machinery and equipment. 

CNC refers to the use of computerized systems to control the manufacturing process of high-precision parts such as cutting, milling, and pressing, and is mainly used in integration with manufacturing equipment for producing machinery. While CNC is a key part of the machine industry, the high level of difficulty required to develop such systems has resulted in 80 percent of the global CNC market being split among Germany, Japan, and the U.S. With KCNC’s successful development of a CNC system, related industries are anticipating a localization rate of at least 30 percent by 2032.

It was in 2019 that plans for CNC development began emerging in earnest in Korea, a time when materials, parts, and equipment (MPE) supply chains started gaining recognition for their importance. The plans were also triggered by the apprehension that setbacks in CNC supply, the entirety of which Korea was dependent on imports, may halt production lines nationwide for the manufacturing industry.

CNC development by individual companies comes with limitations as the process calls for the simultaneous development of various hardware and software technologies, including those needed to produce the main body, motor, and interface. Accordingly, MOTIE launched a project team led by the Korea Institute of Machinery & Materials with the participation of over 20 related companies, research institutes, and academic experts. As a result, KCNC was born in the form of a joint venture by participating companies for collaboration on technological development and commercialization.

After five years of development, field operators and experts finally conducted an objective evaluation last month in which they assessed that the CNC system developed has reached a level of performance similar to that of other advanced countries’ CNC systems in terms of major performance indices, such as machining error and surface quality. Meanwhile, there still exists room for improvement with respect to features like interface user friendliness and availability of different functions.

Korea currently relies on imports for 95 percent of its CNC supply and even the remaining five percent of domestic products require foreign technology. In this regard, the recent CNC system development is expected to substantially stabilize Korea’s manufacturing supply chains and spur significant economic benefits. It is estimated that localizing 30 percent of domestic and overseas CNC demand will create an economic effect of around KRW 200 billion, equivalent to approximately USD 146 million. Swift after-sales service and customized product development are some added merits of localization.

Starting next month, KCNC will enter a one-year demonstration phase for commercialization to conduct tests on high-speed and repeated procedures, processing with various materials and tools, equipment durability, and field performance.

Four major buyer companies, occupying over 90 percent of CNC systems demand, are to participate in the demonstration process. These companies have already submitted letters of intent for purchase to finalize their purchase agreements should demonstration results verify that the developed CNC systems fulfill certain qualifications. Once the demonstration phase is completed successfully, the localized CNC systems will be up for purchase beginning 2026, with relevant industries forecasting that the systems will reach over 30 percent in domestic market share by 2032.
