钻石切边眼镜有什么缺点
钻石切边眼镜下非常流行的一种眼镜，非常，戴上此类眼镜对气质提升帮大。
缺点嘛，一般钻石切边眼镜都是无框的，为此，不利于镜片边缘的保护，如不小心掉地上可能会造成镜片边缘崩边，同时长时间佩戴无框眼镜，镜片与镜架之间的固定也会松懈，同时，切边眼镜一般都是不规则的切边，所以在安装的时候，也可能出现，瞳距校准差异，造成佩戴不适等。

亚克力的原材料及其工艺
楼上的说法，本人有几点意见相左：大板就是规格比较大的板材，宽度60CM+，长度120CM+就可以称做大板了，有的石材没办法取大规格，设定的尺寸也就相对小些。
毛边板是指没切边的条板或大板（光板和毛边才是指有无磨光）。
规格板是预先做成的30*30或者40*40等固定规格的板。
工程板是指根据施工现场规划的图纸，设计出来的板，这些板拼起来就是施工面积图。
所以在加工过程中必须预先试组装起来。
现在，你应该知道工程板和规格板的区别了吧。
