[0002] A double-head CNC high-speed drilling machine for circular tubes is a highly efficient and precise machine tool specifically designed for drilling holes in both ends of circular tubes. It utilizes advanced CNC technology and is controlled by a CNC system, enabling automated and efficient machining. This type of drilling machine is typically equipped with dual spindles, enabling simultaneous machining from both ends of the workpiece in a single setup, significantly improving production efficiency. Furthermore, to ensure machining accuracy and stability, double-head CNC high-speed drilling machines are equipped with high-precision linear guides and feed systems.

The cooling water impacts the fan blades, causing them to rotate. As the blades rotate, the spray holes at the bottom of the rotating frame evenly spray the cooling water, expanding the spraying area. This uniform spraying of cooling water quickly reduces the temperature of the workpiece, preventing deformation or damage to the material due to localized overheating. The expanded spraying range allows the cooling water to cover the entire processing area, ensuring that every part is adequately cooled.

The sieve holes in the collection box realize solid-liquid separation of cooling water and debris. The cooling water is transported back to the water tank through the suction pump and the return pipe. Through effective solid-liquid separation, the debris in the cooling water is removed, the water quality is kept clean, and the service life of the cooling system is extended. The recycling of cooling water not only saves water resources, but also reduces operating costs and improves overall work efficiency. BRIEF DESCRIPTION OF THE DRAWINGS
