Product Description
Precision Manufacturing: Superior CNC Hollow Bolt Technology
Our CNC-machined hollow bolts are precision-manufactured using high-quality stainless steel, titanium alloy, and high-strength alloy steel materials on multi-axis CNC machining centers. This uniquely constructed fastener not only maintains the connection function of traditional bolts, but also achieves specialized features such as lightweighting and media transfer through its hollow design, making it an ideal choice for high-end applications such as aerospace, medical devices, and precision instruments.
Key Material Characteristics:
Reliable CNC machined hollow bolts, high strength and lightweight
Excellent Strength-to-Weight Ratio
The hollow structure significantly reduces component weight while maintaining connection strength. Our materials are rigorously screened to ensure sufficient tensile and shear strength while reducing weight by 30%-50%, meeting the stringent lightweighting requirements of high-end equipment.
Precise Fluid Conductivity
The hollow channel is precision-machined to an inner surface finish of Ra0.8 or higher, ensuring smooth fluid flow. The inherent corrosion resistance of the material enables the bolt to transfer a variety of liquids and gases while maintaining long-term stable performance.
Reliable Structural Integrity
We utilize a one-piece molding process to ensure hollow bolts maintain structural stability under preload and operating loads. Ultrasonic testing for material uniformity and density eliminates any potential structural defects.
Precision Machining
We utilize a five-axis machining center, coupled with specialized deep-hole drilling and precision boring techniques, to ensure micron-level accuracy of the internal and external contours of each hollow bolt. We have developed unique tool paths and cooling solutions tailored to the machining characteristics of different materials, enabling flawless machining of even slender hollow structures with a depth-to-diameter ratio of up to 10:1.
For threading, we utilize precision whirling milling technology to ensure thread accuracy exceeding 6g. Each hollow bolt undergoes rigorous air tightness testing, pressure testing, and dimensional inspection to ensure it meets the highest standards required by industries such as aerospace and medical.
Our Core Strengths
Based on our in-depth understanding of hollow structural components and extensive manufacturing experience, we are able to provide customers with professional hollow bolt solutions. Whether it's a functional bolt that needs to transmit media or a structural bolt that strives for extreme lightweighting, we can achieve precise manufacturing.
