基本解釋

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(yīng)用DF 系統(tǒng)原理設(shè)計(jì)小直逕深孔加工中吸壓送水器的問(wèn)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(shù)措施在小直逕長(zhǎng)距離水平工程孔施工中比較罕見(jiàn)。
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.
