But how can we ensure the rotation is more standardized?
In fact, it's entirely possible using a gear set.
Previously, Ma Lin had significant shortcomings in understanding gear sets.
A metal rod connects to the front of the broaching tool, installed inside a tube, capable of rotating within it.
The metal rod gets stuck inside due to uneven thickness; as the tube moves left and right, the rod also moves sideways, assuming the broaching tool pulls the rifling along the lateral direction.
So, how can we make the metal rod rotate?
The part of the metal rod protruding from the tube is equipped with a gear.
When this gear meshes with a gear set, and as the rod moves laterally about one meter (depending on the actual length of the gun barrel), the gear perfectly rotates twice, driving the metal rod and the broaching tool behind it to rotate twice, thereby cutting out standard rifling.
How do we achieve this function?
