In Taizhou Chuang Yuan Machine Tool Co., Ltd., Precision Gun Drilling is not merely a product—it is a core competence honed over twenty years. Our deep hole drilling machines are engineered to resolve the most demanding hole-making challenges across automotive, aerospace, medical, mold, and energy industries. The process starts with rigorous design validation using FEA to optimize bed rigidity and damping. We employ high-grade cast iron and stress-relief annealing to guarantee long-term stability. Spindles are precision-ground and dynamically balanced to 0.5 g·mm, enabling rotational speeds up to 8,000 rpm. Our proprietary guide bushing system maintains tool alignment within 0.002 mm—essential for deep holes. Each machine undergoes 72 hours of continuous testing and laser interferometry to verify positioning accuracy of ±0.003 mm. With over 20 years of experience, we have exported to more than 20 countries, delivering tailored solutions to clients. In Germany, a turbine shaft manufacturer achieved straightness of 0.15 mm over a depth of 2,000 mm. In the US, a hydraulic cylinder producer increased feed rates by 30% using our high-pressure coolant system. Our machines accommodate diameters from 1.5 mm to 50 mm and depths up to 3,000 mm, achieving surface finishes down to Ra 0.4 μm. We also provide custom tooling, process development, and operator training. Whether you are drilling crankshafts, injector nozzles, or medical implants, our Precision Gun Drilling technology ensures minimal deviation, extended tool life, and reduced cost per hole. Partner with us to elevate your manufacturing precision.
