This invention discloses a fully automatic double-sided polishing device for circular stones, comprising: a conveying mechanism for conveying circular stones; a polishing mechanism disposed above the conveying mechanism for polishing the surface of the circular stones; and a flipping mechanism. This invention achieves continuous polishing of the upper and lower surfaces of the circular stone through the automated coordination of the flipping mechanism, the conveying mechanism, and the polishing mechanism. After polishing one side, the circular stone is automatically clamped and flipped 180° by the flipping mechanism, eliminating the need for manual intervention. This completely eliminates the cumbersome step of manually flipping the stone during the traditional "equipment polishing + manual flipping" mode, avoiding production interruptions and significantly improving production efficiency. Simultaneously, the automated flipping process eliminates the need for manual contact with the circular stone surface, effectively preventing scratches and contamination caused by manual flipping, ensuring product quality consistency and stability, and completely eliminating the safety hazard of large, heavy circular stones slipping and falling during manual flipping.

This invention discloses a silicon ring polishing device, belonging to the technical field of polishing equipment, including a base column, an inner ring polishing mechanism, and an outer ring polishing mechanism. Through the arrangement of the inner and outer polishing mechanisms, the inner and outer walls of the silicon ring can be polished simultaneously. The rotation direction of the outer disk controlled by the first motor is opposite to the rotation direction of the polishing ring, avoiding the silicon ring from rotating together during polishing in the same direction, thereby improving the polishing effect. Simultaneously, during polishing, the outer polishing mechanism can hold the silicon ring in place, preventing it from falling off.

The polishing method comprises the following steps: grinding the soft magnetic alloy; performing chemical mechanical polishing rough polishing on the ground soft magnetic alloy by using a rough polishing slurry; performing chemical mechanical polishing fine polishing on the rough polished soft magnetic alloy by using the polishing liquid, so that the soft magnetic alloy with a smooth and flat surface is obtained. The polishing liquid is green, environment-friendly and pollution-free, and the surface of the soft magnetic alloy after polishing is smooth and flat.

This invention provides a chemical polishing device for preparing stainless steel castings, relating to the field of chemical polishing technology for stainless steel castings. The device includes a column fixedly installed on the surface of a base plate and a sliding ring that slides along the outer wall. The sliding ring and a storage tank are hinged together by a hinge plate. A spring is fixedly installed between the circular plate and the sliding ring. An extension plate is fixedly installed on the side wall of the sliding ring, and a positioning ring is fixedly installed at the end of the extension plate away from the sliding ring. The auxiliary device also includes a vertical plate fixedly installed on the surface of the base plate and a motor fitted onto its surface. A special-shaped gear is fixedly installed at the output end of the motor via a coupling. This invention, through the auxiliary device, allows the storage tank to reciprocate horizontally, thereby moving the chemical reagents contained inside the storage tank. This movement washes over the stainless steel castings placed in the support frame, effectively removing impurities adhering to the surface of the stainless steel castings and improving the polishing effect.
