Although the emergence of non-magnetic drilling tools has brought great convenience to our work, there may be some problems during use, such as thread sticking of non-magnetic drilling tools. So, what are the reasons for thread sticking of non-magnetic drilling tools?Below, the editor will analyze the relevant knowledge points for everyone.
1. Reason for thread damage: The use of non-magnetic drilling tools often causes damage such as collision and deformation of the thread. When making up, the deformed part of the thread may be affected by high tangential and compressive stresses, resulting in plastic deformation and easy sticking problems.
2. Reason for thread parameters: When re threading some threads, basic parameters such as thread height, tightness, or pitch, in addition to the specified tolerance range, will cause the compressive stress to continuously increase, leading to premature thread sticking.
3. Reason for connection: If the connection is improper during connection, there may be a tilt angle between the connecting threads; Causing incorrect and sticking issues. Excessive fastening speed can cause the metal at the friction interface to soften, resulting in adhesion between the female and male buckles, leading to the occurrence of adhesive bonding. In addition, uneven application of thread grease, demagnetization of non-magnetic drilling tools, and incomplete demagnetization can also cause sticking.
