introduction：Ratchet mechanism A one-way intermittent motion mechanism consisting of a ratchet wheel and a ratchet claw。It converts continuous rotation or reciprocating motion into one-way stepping motion。Ratchet wheel teeth are usually one-way teeth﹐The pawl is hinged on the rocker﹐When the rocker swings counterclockwise﹐The drive pawl is inserted into the ratchet teeth to push the ratchet to rotate in the same direction﹔When the rocker swings clockwise﹐The pawl slid over the ratchet﹐The ratchet stops turning。To make sure the ratchet doesnt reverse﹐A check pawl is often installed on the fixed member。The reciprocating swing of the rocker can be made by a crank rocker mechanism﹑Gear mechanism and swinging cylinder are realized﹐In delivering very little power﹐The spine is also driven directly by an electromagnet

introduction：Because the mechanical polishing is mainly completed by hand，Therefore, polishing technology is still the main reason for affecting the quality of polishing。besides，Also with mold material、The condition of the surface before polishing、Heat treatment process and so on。High quality steel is a prerequisite for good polishing quality，If the surface hardness of the steel is uneven or the characteristics are different，Often produces polishing difficulties。Various inclusions and pores in steel are not conducive to polishing。 Influence of different hardness on polishing process Increasing hardness makes grinding more difficult，But the roughness decreases after polishing。Due to the increase in hardness，To achieve lower roughness required polishing time accordingly
