Recently, Dezhou Drillstar Cutting Tool Co., Ltd. (hereinafter referred to as “Dezhou Drillstar”), a company deeply rooted in the deep hole machining field for many years, has continued to exert its strength in the precision manufacturing equipment sector with its independently developed series of gun drilling machines. With its high-precision, high-efficiency, and flexible product advantages, it has won recognition from customers in many parts of the world, becoming an important force in promoting the localization of deep hole machining technology and assisting in the manufacturing upgrade of various industries, demonstrating the core strength of Chinese precision equipment enterprises.
As a professional manufacturer located in Dezhou City, Shandong Province, a deep hole machine tool manufacturing base in China, Dezhou Drillstar has always focused on the research, development, production, and sales of gun drilling tools and gun drilling machines since its establishment. Having cultivated the industry for many years, it has built a complete product system and technology research and development system, owns the self-registered brand “Drillstar,” and is committed to providing global customers with one-stop deep hole machining solutions. The company employs renowned domestic cutting tool professors to guide its technical development and has assembled a team of experienced gun drill R&D engineers and production technicians. Leveraging its independently developed technological processes, Dezhou Drillstar has achieved full-process self-control over gun drill machine tools, from design and production to testing, thus solidifying the foundation of product quality.
In the R&D and manufacturing of its core product, the gun drill machine tool, Dezhou Drillstar has accurately identified industry pain points, overcome numerous technical bottlenecks, and created high-performance, cost-effective products that combine precision and efficiency. Its gun drill machines cover a variety of models, including single-axis, dual-axis, three-axis, and four-axis models. It also offers gun drill and BTA (Browser Aperture Array) composite models, with a hole diameter processing range of 1mm-80mm and a maximum drilling depth of 3000mm. These machines can handle both small, precision holes and large, deep holes, adapting to various workpiece types such as cylindrical and small irregularly shaped parts. Both stand-alone and fully automated line loading and unloading are possible, achieving comprehensive coverage of various processing scenarios.
High precision is one of the core competitive advantages of Dezhou Drillstar gun drill machines. This series of machine tools is equipped with renowned CNC systems from FANUC and SIEMENS, with a maximum spindle speed of up to 6000 r/min. Combined with a high-precision guiding system and servo control, the straightness error of machined holes is ≤0.1 mm/m, the surface roughness Ra≤1.6 μm, and the hole diameter tolerance and coaxiality are strictly controllable. It can easily meet the machining requirements of deep holes with a length-to-diameter ratio >20, and even handle ultra-deep holes with diameters of 0.5~50 mm and depths of several meters. High precision requirements can be achieved in a single pass, eliminating the need for subsequent polishing, significantly improving machining efficiency and product consistency.
To address the pain points of traditional deep hole machining, such as difficult chip removal, rapid tool wear, and poor cooling, Dezhou Drillstar has specifically optimized the chip removal and cooling systems of its gun drills. Employing internal or external chip removal structures, high-pressure cutting fluid (pressure up to 2~10 MPa) rapidly removes chips from the drill tip, completely avoiding chip clogging and effectively reducing tool wear, extending tool life. Furthermore, the machine tool boasts a compact structure and a rigid spindle and feed system, reducing vibration during deep hole machining and further ensuring machining accuracy and stability. It is suitable for the stringent machining requirements of various industries, including aerospace, automotive manufacturing, oil and gas, and mold processing.
Product innovation and customized services are key to Dezhou Drillstar’s market dominance. The company not only offers a comprehensive range of standard gun drills but also develops non-standard tools and machine tools to meet the personalized needs of customers in shipbuilding, mining machinery, and medical device industries. This allows for customized machining solutions and rapid response to diverse and complex machining requirements. Its gun drill products encompass various types, including welded single- and double-edged gun drills, solid alloy small-diameter gun drills, and indexable insert gun drills, with diameters ranging from 1.00mm to 65mm. These tools, combined with the company’s self-produced gun drills, create a synergistic advantage, further enhancing machining accuracy and efficiency while reducing overall operating costs for customers.
With its superior product quality and comprehensive service system, Dezhou Drillstar’s gun drills are sold both domestically and internationally, earning widespread praise from customers worldwide. The company possesses a complete and scientific quality management system, strictly controlling every stage of machine tool production and testing to ensure products meet factory standards. Simultaneously, it has established a comprehensive service system covering the entire process from demand communication, solution design, production and processing to acceptance and delivery, and after-sales service. This provides customers with all-round support, including on-site demonstrations, technical guidance, and remote maintenance, using its professional capabilities to solve deep hole machining challenges, helping enterprises improve quality and efficiency, reduce costs, and increase profits.
Currently, the global manufacturing industry is accelerating its transformation towards high precision and intelligence. Deep hole machining, as a key link in precision manufacturing, is experiencing continuously upgrading market demand. Dezhou Drillstar is seizing this opportunity, leveraging its technological accumulation, continuously increasing R&D investment, constantly optimizing processes, and promoting the iterative upgrading of gun drilling machine tools. This helps domestic precision equipment break free from import dependence and achieve independent control. In the future, Dezhou Drillstar will continue to uphold its original aspiration of “making solid products, building a national brand, and pursuing excellent quality,” empowering the global precision manufacturing industry with higher-quality products, more efficient services, and more cutting-edge technologies. It will work hand in hand with its customers for mutual benefit and write a new chapter in the development of Chinese precision equipment enterprises.
