Drill tool manufacturers analyze the use of drill pipes and joints

When the drill string reaches the critical speed, the drill pipe will vibrate. This vibration will often cause the drill pipe to bend, excessive wear, rapid damage and fatigue failure. In particular, the drill pipe has two types of vibration (node vibration and spring pendulum vibration) when the most unfavorable. The critical speed varies with the length of the drilling tool, the size of the drilling tool, the size of the drill collar and the size of the borehole.

Rock chisel mechanical splitting machine used in stone crushing splitting rock concrete decomposition

Rock chisel mechanical splitting machine used in stone crushing splitting rock concrete decomposition

After the continuous upgrading and transformation of the fierce rock technology, the rock drilling machine can not only use the rock drill to drill holes, but also use the splitting machine to split rocks. The integrated operation saves labor costs and has high mining efficiency. After making full use of second-hand excavators, after the drilling machine head is disassembled, it can also be restored to excavators for excavation operations. It can be applied to rock crushing and splitting and rock concrete decomposition to gnaw hard bones.
