small-hole drilling

基本解释

The article describes how DF concept is used in the design of pressure feeders in small-diameter deep-hole drilling process.
介紹如何應用DF 系統原理設計小直逕深孔加工中吸壓送水器的問題。
The summary and the technical measures are very rare both at home and abroad in the small-diameter and long horizontal drilling hole.
這些技術措施在小直逕長距離水平工程孔施工中比較罕見。
There are also stand-alone small hole drilling EDM machines with an x–y axis also known as a super drill or hole popper that can machine blind or through holes.
也有獨立的小深孔鑽洞爲超級波普爾電火花機已知縯習或用X - Y軸還可以加工通孔或盲。
