Especially when processing springs with larger dimensions, a spring cutter is generally used to cut the end faces of the spring flat before grinding. As a prior art spring end face cutting machine, the China Patent Network discloses a spring end face cutting machine with publication number CN210281028U, which relates to the technical field of spring processing equipment, including a frame, a support roller rotatably arranged on the frame, a drive motor arranged on the frame, a flame cutting machine arranged on the frame, and a positioning device arranged on the frame.
