On the gantry is a drilling power head, which can move up and down (Z axis direction) and rotate no more than 360 degrees. & ltbr & gt

2. The drilling power head is placed horizontally, with a small volume, the total length is less than 450mm, and the width is less than180 mm. The inner ring nozzle with an inner diameter greater than 800mm can be processed, and the outer ring nozzle is not limited. & ltbr & gt

3. The drilling power head can be positioned at will (manually) within the range of not more than 360 degrees, and the spray holes distributed on the inner and outer cylindrical surfaces of the annular piece can be processed separately as required. & ltbr & gt

4. The bit adopts Morse 5# taper hole, and when changing the tool manually, there is a hydraulic tools release mechanism (the company is arbitrary), so it is very convenient, safe and fast to change the tool. & ltbr & gt

5. The drill bit can complete drilling (holes with carbon steel diameter of 5-25), reaming and tapping (carbon steel diameter below 24) as required. Because it is automatic tool loosening, the efficiency is much higher than that of rocker drill. & ltbr & gt

6. The drilling power head can move up and down 400mm along the Z-axis ram, which is convenient for clamping and disassembling workpieces and can adapt to workpieces with different thicknesses. & ltbr & gt

7. The circular workbench under the gantry of this machine tool is a turntable that can be automatically indexed. The turntable is supported by the annular hydrostatic guide rail, which can bear a large load, and can be indexed at any angle driven by AC servo motor, with accurate positioning. & ltbr & gt

8. The turntable of this machine tool can move 2000mm in the X-axis direction, and the movement in the X-axis direction is also driven by AC servo motor with high-efficiency ball screw. Under the control of the machining program, the tool can be automatically returned after each working procedure. With the help of manpower, put on new tools and complete the next process. Ensure the consistency of machining size of each nozzle. & ltbr & gt

9. The machine tool is equipped with an efficient cooling system, so as to ensure the requirements of shape and position size and workpiece surface roughness during machining. & ltbr & gt
