High-Precision Technique of Pakistani Experts Drilling an Old Giant Steel Cylinder

In this video, we'll observe the machining process of a massive steel cylinder carried out in a Pakistani workshop. The process begins with initial drilling to create a center hole, followed by boring to refine the inner diameter and ensure the component's axis alignment. The outer part is then gradually machined to the desired size, followed by finishing to improve dimensional accuracy and surface quality.

Throughout the process, Pakistani workers take regular measurements using precision m...
