Choice of grinding fluid grinding wheel is titanium alloy

       Grinding a titanium alloy grinding and, more importantly, in addition to having a cooling and flushing action is to have suppressed the adhesion of the abrasive grains of titanium and chemical action. For ordinary abrasive grinding wheel, should use water-soluble grinding fluid containing extreme pressure additives, can inhibit the adhesion and grinding cracks occur. The choice of the following recipe preparation grinding fluid. Chloride, fatty acid polyoxyethylene ether 0.5% to 0.8%, 0.5% trisodium phosphate, 1% nitrous steel, triethanolamine 0.5% to 1% of water (balance). It must be pointed out that the use of chlorinated compounds grinding fluid should be cleaned after grinding parts, to prevent the lower part of the anti-fatigue strength. Cubic boron nitride (CBN) grinding wheel is titanium alloy, should not use a water-soluble grinding fluid, causing the grinding wheel china excessive wear and tear, CBN and from the chemical reaction of water at about 800 ℃. You should use oil-based grinding fluid. Wherein the chlorine-containing extreme pressure additive grinding oil composition: Barium Petronate + chlorinated paraffin (oil) + phosphate triethylammonium lipid + base oil.
      The grinding is used, the flow rate should be large enough, per millimeter wheel width not less than 0.5L/min, the higher the grinding wheel line speed, the flow should be larger, and maintain a sufficient pressure to ensure the cooling and flushing action. The tanks have a large capacity, generally 1.5-3 times the flow rate, in order to keep the grinding fluid is at a lower temperature. In addition, high grinding temperature titanium alloy, titanium debris is likely to cause a fire, pay attention to fire safety in the use of oil grinding fluid.
