XT60-1&2镗铣主轴头配电机 + 自动换刀 + 中心出水

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装置，需选择与主轴锥度匹配的中空内冷专用刀柄、拉钉及刀具。

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.
