BTA/單管鉆 BTA/Single Tube Drilling
STS單管系統(tǒng)也稱為BTA系統(tǒng)
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(dǎo)器或連接器在機(jī)床主軸上供應(yīng)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
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.
