NOZZLE STRUCTURE FOR WATER JET CUTTING AND CUTTING APPARATUS HAVING THE SAME

摘要

PURPOSE: A nozzle structure for a water jet cutting apparatus and a cutting apparatus including the same are provided to straightly spray a mixture on objects and appropriately adjust the ratio of super high-pressure water and abrasive material through first and second nozzles. CONSTITUTION: A nozzle structure for a water jet cutting apparatus comprises first and second nozzles. The first nozzle has a first injection flow path. The high pressure water flows in a main flow path inside the first injection flow path. The second nozzle is separated from the first nozzle. The second nozzle has a second injection flow path. A mixture of the water and abrasive flows in the second injection flow path.
