XT50-2鏜銑主軸頭配電機+自動換刀+中心出水

XT50-2-BT50-MB+CTS

主軸頭選用中空油壓打刀缸配合增壓式打刀器使用，專為主軸中心出水而設計；結構緊湊，高速自動換刀的優勢。以壓縮空氣為動力源，油為介質，將輸入壓力變換，以較高壓力輸出產生強大推力的工作原理。主軸貫通內冷裝置，由精密旋轉接頭，高壓冷卻裝置組成及冷卻液精過濾裝置組成，是當今CNC機床高效加工和保證主軸長效運轉的裝置，需選擇與主軸錐度匹配的中空內冷專用刀柄、拉釘及刀具。  

Spindle head choose play knife hollow hydraulic cylinder with supercharged use knife device, specially designed for the spindle center water; The advantage of compact structure, high speed automatic tool change. With compressed air as power source, the oil as medium, the input pressure transformation to produce powerful thrust principle of high pressure output. Main shaft through the cooling device, by the precision rotary joints, high pressure cooling device composition and the cooling fluid of fine filter, is now the CNC machine tool efficient processing and ensure main shaft device of choice for long-term operation, should choose to match the spindle taper hollow cold inside the handle, pull nails and the cutting tool

中心出水內冷的特點：(CTS The characteristics of the cold)

※由于中空內冷主軸的冷卻液是從刀具上噴出的，能夠直接作用在工件上和刀具的切削部位，冷卻效果要優于普通主軸，使加工件的表面質量更好，外冷卻由于受刀具旋轉離心力的影響冷卻液大部份被刀具甩出因此冷卻效果不佳。  

Because of the cold inside the hollow spindle coolant spewing from the tools, can directly effect on the workpiece and cutting  

tool parts, cooling effect is better than ordinary spindle, make better surface quality of machined part, outside cooling due to the

tool most of the effect of rotating centrifugal force coolant was so poor cooling effect the cutting tool.

※更適合于深孔加工，在加工深孔時，通過主軸中心的貫穿孔將冷卻液輸送到刀柄并通過刀柄及刀具上的貫穿孔噴出，所以對刀具的切削部份和工件的冷卻效果明顯要好于外冷卻裝置，而且切屑通過高壓冷卻液能順利地通過鉆頭的螺旋槽快速排出，從而能實現連續切削，提高加工效率和刀具耐用度。 

More suitable for deep hole processing, in the deep hole machining, through the main shaft through hole in the center of the  

coolant to the through hole on the handle and through the handle and cutter, so the cutting part of the tool and workpiece

cooling effect is obviously better than the outer cooling device, and chip through high pressure coolant can smoothly through

the spiral trough rapid discharge bit, which can realize continuous cutting, improve processing efficiency and tool life.

※由于主軸高速旋轉加工時冷卻液經過主軸中心孔時能帶走一部份熱量，這就更有利于提高主軸的使用壽命與主軸精度，同時也能夠避免主軸熱變形而影響加工件精度的問題。

As coolant through spindle spindle high-speed machining center hole part can take away heat, it is more conducive

to improve the service life of the spindle and the spindle precision, but also can avoid the spindle thermal deformation  

and affected the accuracy of machined part.
