Description: Engraving machine spray cooling,Special design,direction of rotation,easy to operate. Standard fixing device,fine spray port, long life. Specification: Material: plastic & metal & brass Size:36 cm (L),hose about 1M Fit for 8mm air pipe Cooling stone/metal/ceramic tile engraving machine For CNC Lathe Milling Drill Machine Features: 1) a lot of water problem solving tools, easier to clean up 2) processing the coolant can save more than 80%, the cooling effect is no less than the conventional water-cooled 3) gas processing chips are blown away, working safer 4) the nebulizer gas and coolant is adjustable, easy to use on different processing conditions 5) Even the super-hard alloy precision machining the workpiece can achieve a smooth surface 6) not only increases the machining cutting speed, save time and reduce processing costs and tool wear NOTES: 1. Clean the liquid shall be used 2. Do not use liquid-corrosive 3. In the liquid without pressure output required to ensure that the air pressure in the range 5-7 KGF / CM2 (atomization and gas, associated gas pressure) 4. Use the liquid viscosity at 68cSt or less Package include: 1x Mist Coolant System Note: Please note that the new type and old type of this product will be sent randomly, and make sure you will not mind before ordering.
