The double-sided grinding apparatus for post-processing of magnetic materials as described in claim 6, characterized in that: The mounting platform (101), placement plate (102), toothed plate (103), primary support column (104), secondary support column (105), connecting column (106), water collection tank (107) and transmission gear (202) are all made of stainless steel. The bottom of the primary support column (104) is flush with the bottom of the secondary support column (105), and the grinding strip (402) has chamfered edges on both sides.

8. The double-sided grinding apparatus for post-processing of magnetic materials as described in claim 7, characterized in that, The method of using a double-sided grinding apparatus for post-processing of magnetic materials includes the following steps: S1, start the drive motor (201), the drive motor (201) drives the transmission gear (202) to rotate, the two sets of transmission gears (202) cooperate to make the synchronous belt (203) rotate, and the polishing liquid is introduced into the water cavity of the connecting block (401) through the two sets of water inlet pipes (403). After passing through the water cavity, the polishing liquid flows out from several sets of water outlet holes at the bottom of the grinding strip (402); S2, depending on the thickness of the magnetic material to be polished, rotate the turntable (410). The turntable (410) drives the secondary bevel gear (408) to rotate through the rotating rod (409). The secondary bevel gear (408) drives the screw (407) to move up or down along the primary bevel gear (406) through the primary bevel gear (406), thereby adjusting the height of the grinding strip (402). Observe the scale of the screw (407) directly opposite the top of the housing (405) and adjust the height of the grinding strip (402) to a suitable level. S3, place the grinding disc (301) on the top of the placement plate (102) away from the grinding strip (402), insert the stabilizing post (302) into the groove, insert the magnetic material to be ground into each placement hole of the stabilizing post (302), and slowly push the grinding disc (301) forward. The grinding disc (301) first partially engages with the timing belt (203). Driven by the timing belt (203), the grinding disc (301) is fed between the toothed plate (103) and the timing belt (203). Driven by the synchronous belt (203), the rotating line moves forward. When it moves to the bottom of the grinding plate (402), the grinding discs at the bottom of the connecting block (401) and the top of the placement plate (102) grind and polish the magnetic material. The polishing liquid lubricates and cleans the magnetic material. Excess polishing liquid is discharged into the water collection tank (107) through the drain hole of the placement plate (102) and can be discharged through the drain pipe of the water collection tank (107). The polished magnetic material is output from the other side of the placement plate (102). S4, repeat S3, continuously polish the magnetic material.
