Since the titanium alloy material tends to fill the grinding wheel, it brings difficulties to the grinding of titanium rods. During grinding, the high temperature rise at the interface between the metal and the grinding wheel causes high residual stress on the grinding surface. , At the same time, the surface finish of the titanium rod is not good.
It is suggested that the following methods can be adopted, which can basically solve these difficulties
1. Choose a suitable grinding wheel, such as silicon carbide grinding wheel, medium grain size (60~80), medium hardness (J~M), surface speed 700~1200m/min, alumina (aluminum oxide powder or corundum) grinding wheel It should be used at a low speed, such as 550~600min. It also requires medium particle size.
2. Adopt lower grinding wheel speed and feed rate; due to the low grinding wheel speed, less sparks are generated.
3. Titanium sparks may catch fire when encountering oil mist, but immersing the workpiece with oil can reduce this danger. Anti-rust ammonium nitrite aqueous solution can eliminate the risk of fire.
4. Cooling with buffer or cutting fluid coolant, good results can be obtained with ceramic bond and chlorinated or vulcanized cutting oil. Regardless of the type of coolant used, good filtration is required to eliminate "fishtail" stains caused by recirculation of titanium particles.
