Which type of titanium alloy drill bit is good
Release Time:
Jul 28,2024
Considering the material properties of titanium alloys. Should be selected for materials with weak affinity for the material. Hard alloys containing cobalt are definitely a good choice. Take the following measures: increase the top angle, grind the angle between the two edges to 135-140 degrees, and increase the back angle at the outer edge of the drill bit by 12-15 degrees. Repair the length of the small horizontal blade to 0. 08--0. 1. To reduce the axial force of drilling. Cobalt titanium alloy drilled well! If using a high-speed steel drill bit, the cutting speed is 7-12m/min, the feed rate is 0.05-0.2mm/r. If using hard alloy, v=25-60m/min, f=0.050.15m/r. When drilling shallow holes, the cutting fluid can be selected as electrolyte, which consists of approximately 7% -10% succinic acid, 7% -10% triethanolamine, and 7% -10% glycerol. Boric acid 7% -10%, sodium nitrite 3% -5%, the rest is water. When drilling deep holes, you can choose to add No. 30 mechanical oil to kerosene in a ratio of 3:1 or 3:2, or you can use sulfurized oil.
