XT60-1&2鏜銑主軸頭配電機 + 自動換刀 + 中心出水
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。
The supercharged type cylinder is adopted for the spindle head, so that it has the advantages of compact structure and high-speed automatic tool change. It is mainly applied to the full-automatic equipment, and can realize to store a certain quantity of cutter and automatic tool changer completing the automatic exchange function of cutter by matching the various tool magazines. The processing efficiency of the CNC machine tool is further improved, and one clamping is realized, namely, many processes can be completed; and it is assembled into the CNC milling machine or component of the spindle system in the machining center. The gearbox is composed of the high speed (1:1), neutral gear and low speed (1:4); and the rough
machining and finish machining become possible at the same time by virtue of the high and low speed switching which can shift the gear.
中心出水內冷的特點 (Characteristics of internal cooling of CTS)
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。
As the cooling liquid of the hollow internal cooling spindle is ejected from the cutter, the cooling effect of the cutting part which can directly act on the workpiece and cutter is superior to that of the common spindle, so that the surface quality of the machined part is better. The external cooling is affected by the rotary centrifugal force of the cutter, and most of cooling liquid is thrown away by the cutter, therefore, the cooling effect is bad.
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。
It is more suitable for the deep hole working. When processing the deep hole, the cooling liquid is transported to the knife handle through the through hole of the spindle center and ejected through the through hole on the cutter,therefore, the cooling effect of the cutting part and workpiece of the cutter is obviously better than that of the external cooling device, and cuttings can be rapidly discharged through the spiral chute of the drill smoothly by virtue of the high-pressure cooling liquid, thus, realizing the continuous cutting, and improving the processing efficiency and cutter endurance.
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。
The cooling liquid can bring a part of heat through the spindle center hole when the spindle rotates and processes at high speed, which is more beneficial to improving the service lifespan and precision of the spindle, and meanwhile, being able to avoid the problems of affecting the precision of the machined part due to the thermal deformation of the spindle.
