Dongguan NC machining factory shares with you: it is so simple to carry out sawtooth machining on the NC lathe. The manual movement of the NC lathe is normal in use. It does not move after moving a certain distance when it automatically returns to zero, and it is normal to restart the manual movement.
The lathe of Dongguan NC machining plant uses economic NC and stepping motor. When moving manually, it moves normally due to its slow speed. When returning to zero automatically, it moves quickly and has a long distance, resulting in mechanical jamming. According to the analysis of the fault, the machining is mainly due to mechanical reasons. After inquiry, it was learned that the machine tool disassembled the motor on another machine tool for use due to inaccurate dimensions during machining. After careful inspection, it was caused by too small gear clearance in the gearbox, which was normal after readjustment.
Machining is a fault caused by human factors, which often occurs in repair without attention. Therefore, attention should be paid to avoid this phenomenon in work.
