By Arvin Donley. It's been said the first flour miller was the first person who chewed on a wheat kernel. While the details of that milestone will never be known, we do know the transition to using millstones instead of molars to extract flour occurred around 6000 BC, and it remained the primary flourmaking method for many centuries.

The milling machine in road works is used for repair works to remove a layer of unwanted material from roads so that a new layer can be created by disposing of the destroyed layer. A milling machine, also known as a cold planer or asphalt milling machine, is used in road construction to remove the top layer of an existing pavement surface.

Origin and Early Development of the Machine Tools. More than 2000 years ago, purely manual methods could no longer satisfy the daily production. There was an arising demand for tools, then the first prototype of the machine tool, tree lathe, appeared, as shown in Figure 2a. When using the lathe, users would step on the lower loop with their feet to drive the middle wooden shaft to rotate ...
