The mechanical NC feeder is a press slide block with a relaxed rod device. When the slider is pressed downward, the feeder fuselage perlin relaxation movement is implemented by the rod. This is because the feeder needs to be punched by adding auxiliary equipment to the slider, which limits the punch's collocation to some extent. However, the benefit of this is that the relaxation is quick, making it ideal for quick steps away from high-speed processing production situations.
