细孔微孔加工
细孔加工，一般是指深径比大于10的微小孔加工，常用于精密元件，细孔加工的成本较高，难度大，加工周期长，一般适合少量孔元件。
规格：
孔径：0.2-1mm；深径比：>10；材料：不锈钢、玻璃、镍、铜等；
Pore processing, generally refers to the depth to diameter ratio greater than 10 micro-hole machining, commonly used in precision components, high pore processing costs,difficult, long processing cycle, usually for a small amount-hole components.Specifications:Aperture: 0.2-1mm; depth to diameter ratio:> 10; Material: Stainless steel, glass, nickel,copper and so on;
