Overview Of What Are The Considerations For The Grinding Of Titanium Rods

As the titanium alloy material has a tendency to fill the grinding wheel, thus bringing difficulties to the grinding of titanium rods. When grinding, the high temperature rise generated at the interface between the metal and the grinding wheel causes high residual stresses on the grinding surface, and at the same time, the surface finish of the titanium rods is not good.
Using the following methods can basically solve these difficulties:.
1, choose the appropriate grinding wheel, such as silicon carbide grinding wheel, the size of the grit is medium (60 ~ 80), medium hardness (J ~ M), the surface speed of 700 ~ 1200m/min, alumina (aluminum oxide, powder or corundum) grinding wheel should be used at a low speed, for example, 550 ~ 600min. the same requirement of medium grain size.

2, the use of lower grinding wheel speed and feed rate; due to the low speed of the wheel, less sparks generated.
3, titanium sparks encounter oil dew may start a fire, but with oil are submerged workpiece, can reduce this danger. Antirust type ammonium nitrite water solution can eliminate the risk of fire.
4, with buffer or cutting fluid coolant cooling, with ceramic binding agent and chlorinated or sulfurized cutting oil, you can get good results. No matter what type of coolant is used, it should be well filtered to eliminate the "fishtail" stains caused by the recirculation of titanium particles.
