Deep Hole Drilling

FuiJe Industrial possesses deep hole drilling (Gun Drilling) capabilities, specializing in drilling holes with depths far exceeding their diameters—situations where traditional drilling methods cannot achieve stable results. Equipped with high-rigidity machinery and professional tooling, we ensure stable machining of high depth-to-diameter ratio holes, maintaining verticality, concentricity, and surface quality.

Maximum depth: Over 300mm (adjustable based on hole diameter and workpiece material)

Machinable materials: Aluminum alloys, carbon steel, alloy steel, stainless steel, and more

Deep hole drilling is commonly applied to precision components such as spindle holes, oil channels, guide post holes, and cooling passages. FuiJe Industrial integrates these processes with preceding and subsequent operations like turning, milling, boring, and grinding to provide customers with efficient and comprehensive manufacturing solutions.
