CAUSE AND TREATMENT OF JAMMING OF DRILL BIT

Posted by demonchen007 on April 14th, 2019

The core drilling machine is a drilling machine, and the drill tip consists of two narrow and long first drill tip surfaces and two triangular hook-shaped second drill tip surfaces. There are three main reasons why the drill bit of the core drilling machine is jammed.

Core drilling machines do not chip well. The drill is jammed because debris cannot be discharged due to the dry drill or small amount of cooling water. During the drilling process, the brittle fracture of the drilling object forms larger particles or there are still small steel bars inside, which cannot be discharged due to the large size, causing jamming. The drill bit is not welded firmly, and sticking occurs due to the dropped bit.

In view of the failure of jammed drill bit of core drilling machine, in order to avoid affecting the working process, it is necessary to take measures to prevent and eliminate it in time. 

When drilling, attention should be paid to the sound. When the sound is abnormal, workers should timely lift the drill bit to check whether there is debris or broken core and take it out in time. In case of drilling objects that are easy to break the core or have large particles of crushed stone or small steel bars, the feeding pressure should be reduced and the drilling situation of the drilling machine should be paid attention to at any time.
