Description

Technical Field

[0001] The utility model belongs to the technical field of machine tool processing, in particular to a high-pressure central water outlet device. Background Art

[0002] High-pressure central water jetting, which uses high-pressure water jets for cooling, cleaning, and machining, is an essential component of modern machine tool processing. A machine tool's high-pressure central water jetting system sprays coolant to cool tools and parts, preventing chips from entangled during operation and disrupting normal operation. As a machine tool accessory designed to improve chip removal efficiency and reduce tool wear, the high-pressure central water jetting system utilizes a high-pressure coolant pump to filter the coolant through a filter to remove impurities. The pressurized coolant is then pumped to the spray nozzles. Chips generated by the cutting tool also flow back into the water tank along with the coolant, completing the coolant circulation process and achieving both cooling and cleaning. The water jetting device is the spraying module of the high-pressure central water jetting system. Its spraying accuracy and range have a direct impact on cooling and cleaning effectiveness. Currently, conventional water jetting devices are mounted on the spindle. While this facilitates positioning, it is difficult to adjust. This is particularly true for complex machining operations that require cleaning and cooling at varying angles, making conventional spray patterns less effective. Summary of the Invention
