The main structural parts of Zhonghong trackless equipment adopt numerical control flame cutting or fine plasma cutting to ensure the blanking accuracy. The welding process has special welding tooling and positioner. The key welds can be welded by welding manipulator. In order to ensure the quality, all high-strength weld beads shall be subject to ultrasonic flaw detection. In order to adapt to the bad mining conditions, the whole annealing process is adopted for the structural parts to eliminate the welding stress and processing deformation. In order to ensure the processing accuracy, tkp6913b CNC boring and milling machine, gmb2560 gantry CNC boring and milling machine and other advanced equipment are used for processing, and the workpiece is clamped once to complete all processing procedures.
