Machinist who started young becomes master

Since joining FAW in 2010 in his early 20s, Yang has specialized in numerical control technology and mastered skills such as making automobile engine cylinders that meet extremely high standards — tolerances of less than 0.015 millimeter.

"There are more than 100 holes in an engine cylinder," he said. "To ensure a close connection between the cylinder and its cover, we must be highly accurate. That is the permanent standard for me and my team."
