WHD Water Cooled Spindle
Water-cooled spindles are core drive components designed to deliver stable, high-speed rotation for CNC machines. Compared with air-cooled spindles, water-cooled spindles use a closed-loop circulating cooling system to continuously remove heat during operation, ensuring consistent accuracy, reduced thermal deformation, and reliable performance in long-term, high-intensity machining applications.
Product Introduction
Our water-cooled spindle is designed for high-precision, high-load machining applications, delivering stable and reliable performance under long-term, high-speed operation. By using a closed-loop water-cooling system, heat generated during spindle rotation is efficiently removed, effectively controlling temperature rise and maintaining machining accuracy.Built with a rigid spindle body, a stable drive motor, and an integrated cooling system, this spindle ensures smooth rotation, strong wear resistance, and consistent output. It is widely used in CNC engraving and CNC milling equipment, where high precision, continuous operation, and surface quality are critical. The water-cooled design significantly extends service life and supports demanding machining tasks across various materials.
