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.

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.

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.
