l Lathe: machining cylindrical, circular, circular holes (higher precision)
l Milling machine: machining the edges, grooves and irregular holes of the workpiece (high precision, high price)
l Drilling machine: drilling, tapping (the distance between the outer circle of the drilled hole and the edge of the workpiece cannot be less than 1mm)
l Shearing machine: rectangular sheet cutting (low precision <±0.5mm>, convenient)
l Punching machine: fast processing according to the mold (suitable for processing a large number of metal plates, but the mold needs to be opened, and the processed metal plate should not be too thick, dangerous)
l Wire cutting: The "Panlong Silk" in martial arts novels or the silk used by Fan Xiaoxuan in "Dragon Gate Flying Armor" can be understood as wire cutting. out of various shapes, but the price is expensive)
l Planer: Partial or entire surface of a large workpiece is ground and grooved (many of its functions can be replaced by a milling machine or a grinder, suitable for the processing of medium or large parts)
l Grinder: It is similar to planer, and the edge and surface are smoothed (it can be ground very smooth, and the surface finish requires a high processing method; but in many cases, it can be replaced by a grinding wheel... rare, a little dangerous)
l Boring machine: dig a round hole or machine a curved surface (a bit expensive)
l EDM: For example, you need to make a very small and deep hole or narrow slit (it can process very hard metal, and the workpiece is required to be conductive, so only metal can be processed... fire maker)
