Superbti is a professional company supplying high performance titanium bars, wire, plates, forgings, tubes and fasteners.

Drilling is also a common processing technology which used in the processing of titanium alloys. During titanium alloy processing part in the drilling process, it often occurs burning knife and broken drill phenomenon, which is mainly due to drill bit grinding bad, chip is not timely, poor cooling and poor system and other reasons caused by poor. Appropriate sharpening bits can solve these problems to a certain extent.

In order to reduce the axial force, inhibit the vibration caused by drilling resistance, depending on the size of the drill bit diameter narrow blade, the width of the general retention of about 0.5 mm. Also at a distance of 5 to 8 mm from the tip of the drill, the drill edge is sharpened and retained about 0.5 mm, which facilitates chip bit removal. The geometry of the drill bit must be sharpened, the two cutting edges should maintain absolute symmetry, which can prevent drilling, the drill only one side of the blade contact the titanium processing part, so that all the cutting force on the side, leading to drill premature wear, And chipping the phenomenon.

Drill edge to always keep sharp, once the blunt, should immediately stop drilling, and re-sharpening. If you continue to use the blunt drill bit to force the titanium processing part, the drill will soon be due to the high temperature of the friction and burn, annealing caused by the drill scrap. According to the drilling depth requirements, should try to shorten the length of the drill, increase the thickness of the drill to increase the rigidity, to prevent drilling due to jitter caused by chipping. Practice has proved that to meet the processing needs of the premise, the shorter the length of the drill, the longer the service life.
