It is also used as a flange on the inlet and outlet of equipment to connect two devices, such as a reducer flange. Punching is a common processing method in the production and processing of flanges. The working principle of a general punching device electric drill is that the motor rotor of an electromagnetic rotary or electromagnetic reciprocating small-capacity motor performs magnetic field cutting and work operation, and drives the operating device through the transmission mechanism, driving the gears to increase the power of the drill bit, so that the drill bit can scrape the surface of the object and penetrate the object better.
