The invention discloses a rotary
cutting machine in the technical field of
cutting machines, which comprises a base, a mounting seat and a clamp, the mounting seat is mounted on the front side wall of the top of the base, a mounting frame is mounted on the top wall of a support,
cutting equipment is mounted on the front side wall of the mounting frame, and a connecting disc is mounted on an output shaft on the right side of the cutting equipment. According to the device, cutting equipment rotates, so that a support rotates above a supporting seat, a rotating rod rotates in an inner cavity of a hole, a pull
rope is wound around the outer wall of the rotating rod, a pressing plate is driven to move upwards, a
touch switch below a supporting block is pressed, an
electromagnet is powered on to be attracted to a magnetic block, and the blade is driven to rotate through the rotating rod; the magnetic block is completely moved into the inner cavity of the placing groove, so that the stopping block is blocked and disappears, and when the connecting disc drives the blade to rotate, the coverage range of the blade is enlarged, it is ensured that the rotating blade can still
cut a machined part, the machined part does not need to be moved again, and the use convenience of the cutting
machine is improved.
