一、圆珠笔芯的元珠作用大我厂一块示值为0.002毫米的瑞士产靠表,因使用不慎碰掉尺寸为φ0.8毫米的钢球,无法修配而闲置,后来发现圆珠笔芯的圆珠的硬度,光洁度和尺寸都符合要求,修配后检查合格,这块靠表又投入使用。二、球面研磨器过去研磨球面,不同尺寸的工件需要不同尺寸的研磨器,很费料,我们用球墨铸铁制作了组合性球面研磨器(如图),它加工方便,节省材料,可对10毫米以下的球面进行研磨。具体的加工方法如
First, the role of ballpoint pen ball beads I plant a value of 0.002 mm Swiss production by table, due to accidentally hit the ball size φ0.8 mm, can not be fitted and idle, and later found the ball-point pen round Beads hardness, finish and size are in line with the requirements, repaired after the check, this piece by the table and put into use. Second, the past, spherical grinding mill spherical, different sizes of the workpiece requires different sizes of grinder, it is a waste of materials, we use ductile iron to make a combination of spherical grinder (Figure), it is easy to process, save material, Millimeters of the following spherical surface grinding. Specific processing methods such as
