When drilling titanium alloys, it is easy to generate long and thin curled chips. At the same time, the drilling head is large, and it is easy for the chips to accumulate excessively or stick to the drilling edge. This is the main reason for the difficulty in drilling Grade 9 Ti3Al2.5V Titanium Pipe. Use short and sharp drills and low-speed forced feed for drilling. The support brackets must be tightened and adequately cooled repeatedly, especially for deep hole drilling. During the drilling process, the drill bit should be kept in the drilling state and not allowed to run idly in the hole, and the drilling speed should be kept at a low and constant speed. Drill through holes carefully. When it is about to drill through, in order to clean the drill bit and drill hole, and remove drill chips, it is best to return the drill bit, and use forced feed when the hole is finally broken, so that a smooth hole can be obtained.
