회전 부품 가공
터닝센터의 발전은 회전부품의 비중이 상당하다 (누군가는 그것이 약을 차지한다고 추정합니다. 1/2). 돌리는 것 외에도, 밀링과 같은 작업, 교련, 그리고 태핑도 필수. 게다가, 회전체의 각 공정에 대한 처리 시간이 상대적으로 짧습니다.. 그러므로, 공작기계의 한번의 클램핑으로 회전체에 대한 다공정 복합가공이 시급하다, 마침내 1970년대 복합 터닝 센터가 개발되었습니다..
Compared with ordinary CNC lathes, the turret tool post of the turning and milling center is equipped with power tools that can rotate the milling cutter, drill and tap. 동시에, the machine tool spindle also has the C-axis function that can be accurately indexed according to the CNC program and interpolated with the X-axis or Z-axis. This 3-axis (엑스, 지, 씨) the control can be performed at a turning center of one clamping part turning body turning, 갈기, 교련, 태핑. So far, it is still the most used composite machining machine tool for rotating parts in industrial production.

Since then, the turning center has further developed in the direction of expanding the range of processing technology. In order to drill or mill holes or slots that deviate from the center line of the rotating body, a turret tool holder with Y-axis control has been developed. And correspondingly introduced a turning center controlled by 4 축 (엑스, 와이, 지, 씨). 하지만, no matter how the single-spindle turning center expands the process range, it still cannot solve the problem of the secondary machining of the back side of the rotating body under one clamping (그건, the machining of the workpiece clamping end). 결과적으로, double-spindle turning centers appeared in the 1980s. Most of the two spindles of this machine tool are arranged oppositely on the same axis, 회전체의 주단부를 선회 가공한 후, 두 번째 스핀들이 자동으로 스핀들에서 공작물을 집어 올려 클램핑 끝부분을 처리합니다..
클램핑 엔드의 가공 작업은 일반적으로 상대적으로 간단하기 때문에, 두 번째 스핀들은 일반적으로 서브 스핀들이라고 불립니다., 그리고 그 힘은 상대적으로 작습니다.. 이중 스핀들 터닝 센터에는 하나의 공구대를 장착할 수 있습니다., 하지만 대부분은 두 개의 도구 기둥입니다, 가공 효율성을 향상하고 공작 기계의 잠재력을 최대한 활용하기 위해. 기계의 같은 쪽에 있는 몸체의 축, 서로 반대되는 스핀들이 장착되어 있습니다. (18.65kW) 보조 스핀들 (11kW). 두 스핀들의 속도는 0~4000r/min입니다., 둘 다 C축으로 제어할 수 있습니다.. The sub-spindle can also move along the axis to pick up the workpiece that has been machined on the spindle. A 10-tool turret tool post is provided above the main spindle and below the sub-spindle. Each tool position on the turret tool post can be equipped with a powered tool with a power of 3.7kW and a speed of 80-8000r/min. The upper tool post is controlled by 3 축 (X1, Y1, Z1), and the lower tool post is controlled by 2 축 (X2, Z2).
The rise of the turning center developed from the turning center. The 5-axis control (엑스, 와이, 지, 비, 씨) turning and milling center became a hot spot in the late 1990s. Not only has it further increased the B-axis control (to make the tool post rotate around the Y-axis), to drill and mill bevels. And instead of using the traditional turret tool post of the turning center, a high-speed and more powerful electric spindle tool post is used instead.
Since the electric spindle on the tool post can only be equipped with one tool at a time (the electric spindle is locked and does not rotate during turning), it is also equipped with an automatic tool changer and a tool magazine like a machining center. The milling and drilling capacity of this machine tool is equivalent to a small or medium-sized machining center. Its essence is to integrate a CNC lathe and a machining center, so it is named a turning-milling center.
The turning speed of the turning and milling center table is higher than that of the original machining center. 동시에, the (전기 같은) spindle of the machine tool must be locked and a turning tool can be installed. The newly developed turning-milling center DMU80FD of German DMG company belongs to this type. The structure of DMU80FD is exactly the same as the company’s DMUP series machining center, and it has 5-axis and 5-face high-speed milling of the P series machining center. For all processing functions, the worktable of this machine adopts direct drive technology, the maximum speed is 500r/min, and the maximum speed of the machine tool spindle is also 2000r/min. 그러므로, after the workpiece is clamped on this machine tool, 5-sided and 5-axis machining and compound machining from milling, 교련, 지루한, tapping and turning can be realized efficiently.
