shank adapter is a key component of the rock drill, connecting the drill rod and the rock drill, and bearing high-frequency
impact and rotation, so the material and quality are very important.
At 2 o'clock in the morning in the tunnel, Captain Cheng was holding onto the hot tail of the drill and was forced to shut down for maintenance for the seventh time. The construction progress this month has fallen behind by 14%, and the contract penalty is fluctuating at a rate of 2400 yuan per hour - at this moment, what you need is not a parameter table, but a truly knowledgeable tail of the project.
Traditional brazing tail fractures are mostly caused by stress cracks that are not visible to the naked eye. We use military grade X-ray inspection and conduct 21 stress tests on each finished product in a 40 ℃ constant temperature workshop. When colleagues were still measuring tolerances with calipers, our laser interferometer had already controlled the ellipticity error within ± 0.03mm - an accuracy equivalent to finding the position of a grain of salt on the surface of a standard football field.
In the actual measurement of the extension section of the Qinghai Tibet Railway at an altitude of 4800 meters, the average service life of ordinary drill tails was 83 hours. Our brazing tail is made of German ThyssenKrupp steel, combined with triple cryogenic treatment process, to maintain stable crystal structure of the brazing tail under working conditions of -25 ℃ to 280 ℃. The measured data of Julong Copper Mine in Xizang shows that the service life of a single piece is 328 hours, and there is no tooth breakage.
The patented conical self-locking structure reduces installation time by 65%. Even novice apprentices can complete precise docking within 2 minutes. Built in wear indicator slot, when the red warning line is exposed by 1.5mm, it reminds to replace it in time to avoid sudden failures. From Atlas to Sandvik, from hydraulics to pneumatics, we provide 12 interface schemes, with 3000+specifications and models in stock. We dare to engrave the warranty period on the packaging box, and the choices of multiple units have proven that using our brazing tail reduces the overall equipment failure rate by 41%.
Every minute of the excavation project is worth a thousand dollars. Instead of wasting the future in the maintenance workshop, it's better to let the professional drill tail snatch back the lost time for you. We are on standby 24 hours a day, ready to customize a battle plan for you at any time.
