XT40-2镗铣主轴头配电机+自动换刀+中心出水
XT40-2-BT40-MB+CTS
主轴头选用中空油压打刀缸配合增压式打刀器使用，专为主轴中心出水而设计；结构紧凑，高速自动换刀的优势。以压缩空气为动力源，油为介质，将输入压力变换，以较高压力输出产生强大推力的工作原理。主轴贯通内冷装置，由精密旋转接头，高压冷却装置组成及冷却液精过滤装置组成，是当今CNC机床高效加工和保证主轴长效运转的首选装置，需选择与主轴锥度匹配的中空内冷专用刀柄、拉钉(CAT40A)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 (CAT40A) and the cutting tool
中心出水内冷的特点：(CTS The characteristics of the cold)
※由于中空内冷主轴的冷却液是从刀具上喷出的，能够直接作用在工件上和刀具的切削部位，冷却效果要优于普通主轴，使加工件的表面质量更好，外冷却由于受刀具旋转离心力的影响冷却液大部份被刀具甩出因此冷却效果不佳。
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.
※更适合于深孔加工，在加工深孔时，通过主轴中心的贯穿孔将冷却液输送到刀柄并通过刀柄及刀具上的贯穿孔喷出，所以对刀具的切削部份和工件的冷却效果明显要好于外冷却装置，而且切屑通过高压冷却液能顺利地通过钻头的螺旋槽快速排出，从而能实现连续切削，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.
※由于主轴高速旋转加工时冷却液经过主轴中心孔时能带走一部份热量，这就更有利于提高主轴的使用寿命与主轴精度，同时也能够避免主轴热变形而影响加工件精度的问题。
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.
