摘要
光学零件制造领域中,用传统的方法在微晶玻璃上加工高精度内孔存在很多困难,如钻孔时常出现椭圆、中心偏、锥形、爆边等问题。为了解决这些问题,利用简单的钻床和万能外圆磨床设备,在微晶玻璃上完成钻孔、扩孔、磨边加工后,得到了内孔尺寸精度为0.01mm、内孔与外圆同轴度为0.01mm的高精度圆孔。生产实践表明:该工艺重复性良好,加工性能稳定。不仅解决了玻璃钻孔常见问题,而且得到了高精度玻璃内孔。
Abstract
In the processing of common optical elements,there are many problems in drilling high-precision holes on the glass ceramics with the traditional drilling technology. The common problems are ellipse,decentration,taper and edge cracks et al. To resolve these problems, a new drilling technology was used, and a high-precision inner hole, whose diameter tolerance and coaxiality were 0.01mm, was prepared on a glass ceramic by using a simple drilling machine and a universal cylindrical grinder. The production practice shows that this process is repetitive and steady. The problems existing in the glass drilling were solved and the high-precision inner holes were obtained.
