As a precision machining equipment, the development of boring and milling machines can be traced back to the Industrial Revolution in the 19th century. Early boring machines could only perform simple hole machining, while milling machines were machine tools that used milling cutters to mill workpieces. In addition to milling flat surfaces, grooves, gear teeth, threads, and spline shafts, milling machines could also process relatively complex profiles. After integrating the functions of milling machines in the mid-20th century, they gradually evolved into composite machines integrating multiple processes such as boring, milling, and drilling, which significantly improved the machining efficiency of the manufacturing industry.
With the development of the times and advances in science and technology, boring and milling machines—with boring spindles and milling heads as their core components, paired with high-precision guideways and numerical control systems—can achieve multi-surface and multi-station machining of workpieces. They feature strong rigidity and high precision, are capable of processing various materials such as cast iron, cast steel, and forgings, and meet the machining needs ranging from small and medium-sized parts to large components.In terms of application, boring and milling machines are widely used in fields such as machinery manufacturing, aerospace, and automotive industry. They can not only process complex box parts like cylinder blocks but also complete curved surface milling of large molds, making them key equipment for achieving high-precision and integrated processing.
At the 20th Anniversary Celebration of the Shareholding System Reform of CITIC IC on October 17, 2025, CITIC IC grandly launched the newly purchased TK6920 CNC Boring and Milling Machine. This machine has a boring spindle diameter of 200mm, a boring spindle stroke of 1200mm, and a ram stroke of 1200mm. Featuring large torque and a wide speed range, this CNC boring and milling machine is compatible with cutting tools of different materials and sizes, and can perform heavy cutting and precision machining on workpieces of different sizes.
CITIC IC, a heavy machinery manufacturing base in the Central Plains region, has regarded technological innovation as the core driving force for its development throughout the 20 years since its shareholding reform. The company not only owns a wealth of mechanical processing equipment, but also actively cooperates with universities to build an innovation system integrating production, education, research and application. It continuously overcomes technical difficulties and promotes the intelligent upgrading of products.The successful launch of the TK692 CNC boring and milling machine this time is not only an affirmation of past achievements, but also an incentive for future development. Taking this as an opportunity, CITIC IC will continue to increase R&D investment, deepen cooperation with all parties, and write a more brilliant and splendid chapter for its future with better products and services!
