This invention relates to the field of machining tool technology, and more particularly to a mirror-finish roller burnishing cutter head. The cutter head includes a cutter head body with multiple mounting positions for mounting roller burnishing heads. Each mounting position is equipped with an adjustment mechanism, which independently adjusts the axial extension of the roller burnishing head relative to the end face of the cutter head body. This invention improves machining efficiency by providing multiple roller burnishing heads on the cutter head body and independently adjusting their axial extension. Adjusting the axial extension of each roller burnishing head through the adjustment mechanism ensures that the working end faces of each head are coplanar, eliminating end tooth runout and guaranteeing uniform pressure. Furthermore, when a roller burnishing head wears out, it can be individually compensated or replaced, extending tool life. This effectively solves the technical problems of low planar efficiency in single-head roller burnishing cutters and large end tooth runout in multi-head roller burnishing cutters, leading to uneven pressure and poor flatness.

The invention discloses a polishing device for a ship roller fairlead with a debris collection function, relates to the technical field of roller fairlead polishing, and is used for polishing the drum of the roller fairlead. The polishing device comprises a workbench, a clamping module, a polishing module, a grinding module, a debris guiding module and an impact nozzle. The workbench is placed on a plane, connected to the clamping module, fixedly connected to the polishing module, fixedly connected to the grinding module, fixedly connected to the debris guiding module, and fixedly connected to the grinding module. The device adjusts the posture of flaky debris hitting the drum through the debris guiding module, so that the surface of the flaky debris is perpendicular to the flight direction, thereby increasing air resistance and making the surface of the flaky debris collide with the drum to prevent the sharp edges of the flaky debris from scraping the drum. The impact nozzle cleans the molten metal debris attached to the grinding wheel through a pulse jet, and removes abrasive particles that cannot fall off normally after wear.
