Description

Предмет изобретени Subject invention

Способ подготовки заготовок, например, оптических линз дл  базировани  при блокировке по жесткому методу на наклеечном приспособлении , в теле которого выполнены конические лунки, отличающийс  тем, что, С целью повышени  точности и производительности , заготовку линзы кругл т с треоуемои точностью и образуют на ней конические фаски , причем угол между образующей конической поверхности фаски и образующей конической поверхности лунки выдерживают меньшим или равным половине величины допуска на децентрирование в угловой мере.The method of preparing blanks, for example, optical lenses for a base when locked by a rigid method on a gluing device, in the body of which there are conical holes, characterized in that, in order to increase accuracy and productivity, the lens blank is round with three grids and conical chamfer, and the angle between the forming conical surface of the chamfer and forming the conical surface of the hole withstand less than or equal to half the amount of tolerance for decentration in the angular measure.
