The worktable kept adjusting its position automatically as several nimble mechanical arms worked across its surface with different tools.
Every movement was precise, without a single wasted motion, and the tools moved with a smooth, flowing grace that was a pleasure to watch...
In less than ten minutes, a square block of glass had been cut into a circular lens, its appearance already almost identical to the drawing Professor Zhang had provided.
But that was only the beginning. The main event came next: grinding the component's surface to meet the required surface roughness.
A mechanical arm slowly brought a grinding wheel toward the glass. The wheel appeared completely still, but it was actually spinning at high speed.
Professor Zhang frowned slightly. "Mr. Shen, shouldn't this surface finishing be done with a noncontact laser tool head?"
He was anxious. He had watched Craftsman God No. 1 effortlessly turn the glass block into a lens, and even to his naked eye, its precision was already extremely high. The light it refracted was practically perfect. At the very least, domestic machine tools would struggle to reach that standard.
Yet now, for the subsequent high-precision machining, the machine was still using an ordinary grinding wheel. That was not what he had expected.
Shen Bing smiled confidently. "Don't worry, Professor Zhang. There are two reasons other machine tools don't dare use grinding wheels for atomic-level surface machining. First, with mechanical grinding, the forces acting between the parts affect the equipment's precision. Second, the surface roughness of the grinding wheel itself rarely meets the requirements. But in our machine, every structural component fits together with atomic-level precision, and they're extremely hard. Even intense mechanical contact won't cause any change in precision. Besides, this grinding wheel was specially made. Even the top players in machine tool manufacturing,
