brand new and high quality Material: Plastic, Metal and Brass Color: See pictures Description: Engraving machine spray cooling, Special design,direction of rotation Easy to operate. Standard fixing device,fine spray port, long life. Specification: Fit for 8mm air pipe Cooling stone/metal/ceramic tile engraving machine. For CNC Lathe Milling Drill Machine. Features: A lot of water problem solving tools, easier to clean up. Processing the coolant can save more than 80%, the cooling effect is no less than the conventional water-cooled. Gas processing chips are blown away, working safer. The nebulizer gas and coolant is adjustable, easy to use on different processing conditions. Even the super-hard alloy precision machining the workpiece can achieve a smooth surface Not only increases the machining cutting speed, save for time and reduce processing costs and tool wear. NOTES: Clean the liquid shall be used. Do not use liquid-corrosive. In the liquid without pressure output required to ensure that the air pressure in the range 5-7KGF / CM2 (atomization and gas, associated gas pressure). Use the liquid viscosity at 68cSt or less. Size: See the piture Quantity:1Pc (The Fog nozzle is not included) Note: Due to the difference between different monitors, the picture may not reflect the actual color of the item. Thank you! Package includes: 1Pc X Mist Coolant System
