| 关于打孔机 About the punch 如果钻头上裹着胶状固体一定要清理干净否则会造成打孔过大。 If the bit is coated with colloidal solid, it must be cleaned up or it will cause excessive drilling. 三孔连线一定要成水平线，否则会造成散光轴向不准。可将镜框靠在焦度计的水平杆上先打出三点水平线，然后依此线来打孔。 The three hole connection must be horizontal, otherwise the astigmatism axis will be inaccurate. The frame can be placed against the horizontal bar of the focimeter to make a three-point horizontal line first, and then drill holes according to the line. 2.关于金属衬板的使用 2. Use of metal lining plate 金属衬板永远是垫在模板的凹面（不管左眼还是右眼都垫凹面），金属衬板要尽量用大的，不超过模板边缘即可，衬板小了会有点扭曲变形全框模板太薄，如不垫金属衬板磨片过程中模板会扭曲变形 The metal lining plate is always placed on the concave surface of the formwork (no matter the left eye or the right eye). The large metal lining plate should be used as much as possible, not more than the edge of the formwork. If the lining plate is small, it will twist and deform a little. The full frame formwork is too thin. If the metal lining plate is not placed, the formwork will twist and deform during the grinding process. 3.关于打滑 3. About slip |
