introduction: 1.definition:Use sand belt,The method of machining the workpiece in the corresponding contact mode according to the processing requirements is called abrasive belt grinding。It is a new process method。 2.Sand belt production characteristics: Most of the abrasives used in the belt are selected needle-like abrasive particles,The electrostatic sand planting process is applied,Make the abrasive particles stand upright on the sand belt matrix and the edge upward,Aligned neatly and evenly,Therefore, the abrasive particles have good isometric properties,The space between abrasive particles is large,Small contact area between abrasive particle and workpiece,And all abrasive particles can be cut。 3.Abrasive belt grinding characteristics:High efficiency、Low grinding heat,Heat dissipation

introduction:Intermittent motion mechanism A mechanism that converts the continuous motion of the active part into the periodic motion of the follower with pauses。The intermittent motion mechanism can be divided into two categories: one-way motion and reciprocating motion。 One-way intermittent motion mechanism This mechanism is widely used in production﹐Such as the feed movement of the workpiece on the shaper﹐The rotation motion of a tool on a turret lathe﹐The step conveying movement on the assembly line。The key to the design of this mechanism is to realize the stop in unidirectional motion。During the movement of the mechanism﹐When the active part is out of contact with the follower﹐Or although not disengaged but the active part does not push﹐The follower produces no motion。Ratchet mechanism﹑slot
