This invention belongs to the field of underground tunneling technology, specifically a cutting mechanism and tunneling machine. It includes a right cutting section and a left cutting section. The right cutting section includes: a right cutting head, which is driven to rotate by a right cutting drive to cut and crush coal / rock; and a right cutting fixation, which is used to install the right cutting head and the right cutting drive, and is equipped with a right swing cylinder lug I. The left cutting section has the same structure as the right cutting section. The tails of the right and left cutting sections are mounted on a rotating mechanism. The rotating mechanism is installed in the middle of a longitudinal swing mechanism and can rotate. The longitudinal swing mechanism is mounted on a support frame. The structural design of the dual cutting mechanism of this invention features an integrated cutting mechanism design, resulting in a small size. The multiple cutting methods (paths) of the dual cutting mechanism can also achieve the shaping of underground tunnels.

The application discloses a micro-groove network structure ball head dressing device and method based on magnetic field enhanced force rheology, wherein the dressing device comprises a polishing tank containing polishing liquid, a jig is arranged in the polishing tank, a workpiece is fixed in the polishing tank by the jig and is immersed in the polishing liquid, and the dressing device further comprises a magnetic ball head connected with a driving device through a rod. The dressing method is applied to the dressing device and comprises the following steps: fixing the workpiece; setting a ball center of the ball head on a rotary center line of the workpiece, adjusting an oblique plane of the rod relative to a tangent plane of a concave surface of the workpiece, and forming the same gap between the ball head and the workpiece at different positions of the concave surface; preparing the polishing liquid and pouring the polishing liquid into the polishing tank until the workpiece to be processed is immersed; and driving the ball head to feed and process by the driving device, so that the polishing medium in the polishing gap generates local thickening and solidification and other rheological effects, under the action of flow pressure effect, "particle cluster" containing abrasive grains micro-cut the surface of the workpiece, the surface material of the workpiece is removed, and then the dressing is realized.
