Features: 1) CNC water cutting machine is equipped with fully close axial slide system 2) The infrastructure is made of stainless steel, adjustable water slot and water excessive device 3) The pure water or abrasive material cutting head can be equipped with automatic sand feeding device 4) The pure water or abrasive material cutting device features fine cutting effect and reliable performance 5) The system boast of divided structure plug and play function, built-in cabinet and power cabinet 6) The processing driving is controlled through CNC system, the system is driven by step motor so as to ensure precision 7) The working pressure reaches 300MPa 8) The max. displacement reaches 3.0L/min 9) The work piece won't produce thermal effect, hardening and stress as well as distortion 10) The procedure produces no smoking, no dust and steam fog 11) The niche is small and flat 12) Fast cutting and high precision 13) The system can almost cut any material with the thickness from film to 150mm 14) Straight cutting and plane or curve cutting The high pressure water tank and the oil tank lid are directly connected with screws, therefore it features simple repairing and precise assembling. The high pressure sealing ring is precisely made by applying imported compounded materials. The sealing performance and life are largely improved. The reversing unit applies newest design and the proximity switch applies Japan OMRON parts. The effect of reversing and oil sealing are largely improved. The screws and guide rails are provided by renowned Taiwan manufactures. The X and Y axis applies unique oil dipping lubricating, with the combination of effective waterproof and dustproof structure. It assures the processing precision of the machine and prolongs the life of the screws and guide rails to the maximum. The cutting head is equipped with reliable pneumatic high pressure water switch control unit, largely improving the production efficiency. The unique sand valve design enables the sand to flow smoother and the cleaning becomes more convenient, as well as preventing the occurrence of water leakage.
