Active tool changer (ATC) malfunction. More than 50% of the faults of the machining center machine tools with automatic tool changing equipment are related to the automatic tool changing equipment, mainly manifested in: tool magazine movement problems, large positioning errors, unstable manipulator gripping tool holders, and large manipulator movement errors Wait.

When the fault is serious, the tool change action is stuck, and the lathe is forced to stop working. It is used to detect the pressing fault of the travel switch of each axis movement direction. In CNC machine tools, in order to ensure the reliability of the automatic operation, many travel switches are used to detect the movement direction.

After the machine tool runs for a long time, the movement characteristics of the moving parts change, the reliability of the travel switch pressing equipment and the change of the quality characteristics of the travel Custom Automotive Stamping Dies Parts switch itself have a great impact on the occurrence and elimination of the faults of the lathe.

The lathe feed drive chain is faulty. Since rolling friction pairs are widely used in the guide rails of CNC machine tools, the failure of the feed transmission chain is mainly caused by the reduction of moving quality, such as mechanical parts not moving to the regular position, operation suspension, decreased positioning accuracy, increased reverse clearance, mechanical Creeping, bearing noise becomes larger (usually after a crash), etc.

These problems can be solved by adjusting the preload of each motion pair, adjusting the loose link, improving the motion accuracy, and adjusting the compensation link.
