What is the range of Neway’s deep hole drilling capabilities?
At Neway, our deep hole drilling services are engineered to meet the most demanding specifications across a diverse range of industries. We specialize in creating precise, stable, and high-quality deep holes in various materials, which is a critical process for components in hydraulic systems, fuel injection apparatus, and high-pressure fluid handling. Our capability is defined not just by the machinery we use, but by our integrated approach that combines advanced CNC Drilling Service with expert process design and material science.
Defining Our Technical Specifications for Deep Hole Drilling
The term "deep hole" typically refers to a hole with a depth-to-diameter ratio (L:D) greater than 10:1. Neway's expertise extends far beyond this baseline, handling complex challenges with consistent reliability.
Depth and Diameter Range: Our equipment is capable of producing holes with a minimum diameter of 3mm (0.118 inches) and a maximum diameter of 50mm (1.97 inches) and beyond. We can achieve exceptional depths, routinely handling depths of 1 meter (39.37 inches) and, depending on the component geometry and material, extending up to 2 meters (78.74 inches) or more. This enables us to support a wide range of components, from compact medical device parts to large-scale Industrial Equipment parts.
Achievable Tolerances and Surface Finish: Precision is paramount. We maintain tight diameter tolerances within IT8 to IT9 grades. Furthermore, we can achieve superior surface finishes, starting from Ra 1.6 μm (63 μin), and, with subsequent processing such as electropolishing for Precision Parts, can achieve even smoother surfaces for applications requiring minimal friction and fatigue initiation sites.
Advanced Processes and Material Compatibility
Success in deep hole drilling is contingent on selecting the right technique for the material and application. Neway employs industry-proven methods to ensure optimal results.
Gun Drilling (BTA Deep Hole Drilling): This is our primary method for achieving high-precision, straight deep holes with L:D ratios exceeding 100:1. This single-lip drilling process uses high-pressure coolant to evacuate chips, ensuring excellent surface finish, straightness, and roundness. It is the ideal solution for critical components in the Aerospace, Aviation, and Oil and Gas sectors.
Material Expertise: Our processes are refined for a vast spectrum of materials. We efficiently drill into various Aluminum Alloy grades, all common Stainless Steel types, such as SUS304 and SUS316, as well as high-strength Carbon Steel. We also possess specialized expertise in machining challenging exotics, such as Inconel 718 and Ti-6Al-4V (TC4), where controlling heat and tool wear is critical.
Integration with Comprehensive Manufacturing and Finishing
Deep hole drilling is rarely a standalone operation. At Neway, it is seamlessly integrated into a broader One Stop Service to provide a fully finished component.
Pre and Post-Machining: The component requiring deep hole drilling is often first shaped through our CNC Milling Service or CNC Turning Service to establish its basic geometry. After drilling, we can perform secondary operations, such as CNC Boring Service to achieve precise diameters or CNC Grinding Service to attain ultra-tight tolerances on the outer dimensions.
Specialized Surface Treatments: For internal bore surfaces that require enhanced performance, we offer specific finishing services. Electroplating Services for CNC Parts can add a wear-resistant chrome layer, while CNC aluminum anodizing services provide corrosion resistance and improved surface hardness for aluminum components.
Application in Demanding Industrial Sectors
Our deep hole drilling capabilities are a foundational technology for critical applications across the key industries we serve.
Hydraulic and Pneumatic Systems: We manufacture precision cylinders, pistons, and manifolds for the Automotive and industrial automation sectors, where bore straightness and surface quality directly impact system efficiency and longevity.
Energy and Power Generation: Components for fuel injection systems, turbine cooling channels, and heat exchanger tubes all rely on the precision and reliability of our deep hole drilling processes, serving the Power Generation industry.
Tooling and Mold Making: We provide solutions for mold makers requiring conformal cooling channels, which are essential for improving cycle times and part quality in Rapid Molding and mass production.
In summary, Neway's deep hole drilling range is characterized by its technical depth, material versatility, and seamless integration into a full-service manufacturing workflow. We don't just drill deep holes; we deliver precision-engineered bore solutions that meet the stringent requirements of the world's most advanced industries.
