且，主夾板在生產層面上，對于加工精度有著較高的要求，孔徑與凹槽深淺的加工精度據悉至少也要達到百分之一毫米甚至是千分之一毫米。百萬人收藏的手表知識大全，一篇帶你脫離新手的腕表知識大全L螺釘擺輪上的螺釘主要有兩個作用。其一為平均擺輪的重量分布，也就是所謂的配重。要知道，在雙金屬擺輪的那個年代，因為加工精度的限制所以無法實現擺輪重量的平均分布。彼時，工匠會選擇在擺輪上安置對角對稱的不可自由旋轉的螺釘，從而實現平均擺輪重量分布的目的。但如今隨著加工精度的提升，該作用逐漸變得不再那么必須。其二為實現手動調節(jié)擺輪轉動慣量的目標。整個調節(jié)過程中，雖然擺輪與螺釘的重量都未曾發(fā)生變化，但因為旋入或旋出的關系，螺釘離擺輪中心的距離產生了相應的變化，從而最終影響擺輪的轉動慣量，以此調節(jié)手表的走時快慢。額外一提的是，目前螺釘的安裝位置主要分外擺輪外緣與擺輪內緣兩種；至于螺釘的數量，則無定數。
