BTA/單管鉆 BTA/Single Tube Drilling

STS單管系統(tǒng)也稱為BTA系統(tǒng)。冷卻液通過壓頭裝置供應到工具，壓頭裝置密封并夾緊零件。此外，冷卻劑通過鉆桿和正在鉆孔之間的空間被引導到切割面這種正向冷卻液流既提供了鉆頭潤滑，又提供了適當?shù)呐判剂髁俊Ｋ樾己屠鋮s液的組合通過工具和鉆桿的內(nèi)徑在內(nèi)部返回，然后返回冷卻液。

The STS Single Tube System or sometimes referred to as the BTA system. Coolant is supplied to the tool through a pressure head unit which seals and clamps against the part. Also, the coolant is directed to the cutting face via the space between the drill tube and the hole being drilled. This positive coolant flow provides both drill head lubrication and proper flow for chip removal. The combination of chips and coolant returns internally through the l.D. of the tool and drill tube and then back to the coolant.

雙管鉆/噴吸鉆 Double Tube Drilling/Ejector Drilling

雙管系統(tǒng)“DTS”或有時被稱為鉆孔“噴射器”系統(tǒng)，是指通過特殊的冷卻液誘導器或連接器在機床主軸上供應冷卻液。此外顧名思義，該鉆井系統(tǒng)由一個外管和一個內(nèi)管組成，該外管和內(nèi)管一端連接到冷卻劑誘導器，另一端通過一個快速導程四起點螺紋連接到鉆頭。

The double tube system “DTS"or sometimes referred to as the "Ejector" system of drilling is where the coolant is supplied at the machine spindle through a special coolant inducer or connector. Also, as the name implies, this drilling system consists of an outer and inner tube that is connected to the coolant inducer at one end and to a drill head at the other end by means of a fast lead, four-start thread.
