Introduction to CNC Technology

rock drilling tools

CNC technology is an advanced technology that controls mechanical movement and processing through digital signals. It is a set of technologies of the modern manufacturing industry that integrates traditional mechanical manufacturing technology, computer technology, modern control technology, sensor detection technology, network communication technology, and optomechanical technology. It has the characteristics of high precision, high efficiency, flexible automation, etc., and plays a vital role in realizing flexible automation, integration, and intelligence in the manufacturing industry. The emergence of CNC technology has significantly improved processing accuracy and production efficiency, reduced labor intensity, and is an indispensable part of the modern manufacturing industry.

Advantages of CNC technology in rock drilling tool processing

Improve production efficiency and shorten the production cycle

The traditional method of processing rock drilling tools relies heavily on manual operation and adjustments, resulting in low production efficiency and challenges in ensuring processing accuracy. The application of CNC technology has completely changed this situation. By programming the processing path and parameters, CNC machine tools can automatically complete the entire processing process from blank to finished product, significantly improving production efficiency. At the same time, CNC processing also realizes the continuity and stability of the processing process, reduces production interruptions and delays caused by human factors, and further shortens the production cycle.

Improve processing accuracy and ensure product quality

As an essential tool for mining and rock drilling, the processing accuracy of rock drilling tools is directly related to the performance and service life of the product. CNC technology achieves precise control of the processing process through high-precision CNC systems and precision measuring equipment. Parameters such as cutting speed, feed rate, cutting depth, and others can be accurately adjusted and optimized according to specific requirements. This high-precision processing method not only improves the surface finish and dimensional accuracy of rock drilling tools but also reduces errors and scrap rates in the processing process, thereby ensuring the overall quality of the product.

Realize complex structure processing and expand product application areas.

The structure of rock drilling tools is often complex and diverse, including T-threads, tapers, and other specific structures. Traditional processing methods are often unable to cope with the processing tasks of these complex structures. However, CNC technology, with its flexible processing methods, easily facilitates the machining of complex structures. It enhances the adaptability and functionality of rock drilling tools and broadens their application areas and market prospects.

Specific application of CNC technology in rock drilling tool processing

T-type thread processing

T-type thread processing is accomplished on standard CNC lathes using the “development method.” The tool trajectory aligns with the thread rotation direction, allowing for size adjustments as needed to meet theoretical design specifications. This method enhances processing efficiency and ensures precise thread profile dimensions and surface finish.

CNC machine tool machining

Rock drilling tools are processed using high-precision CNC machining centers. By matching special wear-resistant coating tools and precision measurement technology, the machining accuracy error is reduced, and the quality of the solid teeth and the overall performance of the products are improved.

Complex surface processing

Some parts of rock drill tools may have complex curved shapes, which are difficult to be processed by traditional machining methods. CNC technology can easily meet this challenge by converting complex surfaces into computer-recognizable data through 3D modeling and simulation technology and then accurately machining them by CNC machines.

Processing after heat treatment

Rock drilling tools often need further processing after heat treatment to eliminate deformation and improve surface quality. CNC technology can achieve rapid processing and correction of heat-treated workpieces while ensuring processing accuracy, thereby improving the overall quality of the product.

CNC technology brings market opportunities and challenges

With the widespread application and promotion of CNC technology in rock drilling tools, the market has ushered in unprecedented opportunities and challenges. On the one hand, the application of CNC technology has promoted the transformation and upgrading of the entire industry, leading to technological progress and improved added value and market competitiveness of products. On the other hand, with the intensification of domestic and foreign market competition and the continuous changes in consumer demand, companies are also facing higher pressure and challenges. How to maintain a leading position and continue to innovate and develop in the fierce market competition has become a question that every company needs to think about.

Future outlook: CNC technology leads a new direction in rock drilling tools processing

Looking to the future, the application prospects of CNC technology in rock drilling tool processing will be broader. With the continuous development and innovation of technology, CNC machine tools will become more intelligent, automated, and integrated. At the same time, with the constant emergence and application promotion of new materials and new processes, the processing methods of rock drilling tools will also become more diversified and efficient. It will bring more opportunities and challenges to the rock drilling tools processing industry. Additionally, it will promote the entire industry to a higher level of development.


The use of CNC technology in the processing of rock drilling tools not only enhances production efficiency and accuracy but also reduces labor intensity, thus promoting the advancement and growth of the entire industry. For enterprises engaged in rock drilling tool manufacturing, actively introducing CNC technology and improving their technical level and innovation ability will be the key to responding to market challenges and enhancing competitiveness. We believe that soon, CNC technology will play a more vital role in the rock drilling tool industry and contribute more to the prosperity and development of the industry.
