8986微晶玻璃是一种具有很低线膨胀系数、高硬度、高脆性和低导热率的非金属材料,在惯导和光学器件中有重要用途。由于其固有的机械物理性能,给机械加工带来了严重困难,所以制造厂商称这种材料为不能进行机械加工的微晶玻璃。我们因科研任务的急需,要求在8086微晶玻璃上加工出孔径小于1.5mm,长径比L/d≥100的微深孔,且对孔的几何精度、表面粗糙
8986 Glass-ceramic is a non-metallic material with low coefficient of linear expansion, high hardness, high brittleness and low thermal conductivity, which has important applications in INS and optics. Due to its inherent mechanical and physical properties, mechanical processing has brought serious difficulties, so manufacturers said the material can not be machined glass-ceramics. Due to the urgent need of scientific research, we need to process micro-deep holes with the diameter of less than 1.5mm and the aspect ratio of L / d≥100 on 8086 glass-ceramics, and the geometric precision of hole, surface roughness
