騎馬訂書刀上刀和下刀在工作中就像剪刀一樣裁剪。如今的高速聯(lián)動線每小時可達到30000次的裁切，在這種情況下要求刀片有較好的公差配合，可以在設備上長時間運轉，因為每次停機換刀都會使加工成本上升。

 The upper knife and the lower knife are cut like scissors at work. Today's high-speed linkage line can cut up to 30000 times per hour, in which case the blades are required to have a good tolerance fit and can run on the equipment for a long time, because each stop and tool change will increase the processing cost
