The structure of CNC drilling machine for tube sheet :
1. The machine tool of the tube sheet CNC drilling machine adopts the form of fixed bed table and movable gantry.
2. The machine tool is mainly composed of the bed, worktable, gantry, power head, numerical control system, cooling system and other parts.
3. There are 3 axes in the CNC drilling machine for tube sheet. The bed is equipped with heavy-duty linear guide rails. The gantry can move longitudinally along the guide rails (x-axis). The gantry beam is also equipped with linear guide rails, and the slide plate can move laterally along the guide rails ( y axis), the slider is equipped with a slider, the power head is equipped with a guide rail, the power head can move vertically on the slider (z axis), and the x, y, and z axes are driven by CNC servo motors and ball screws.
4. The control adopts Kaiendi numerical control system, the electric drive adopts high-precision value series servo motor drive, equipped with RS232 interface and color display screen, Chinese operation interface, on-site/external USB input workpiece, easy operation, equipped with all-digital high-speed handwheel , making your operation more convenient and faster. In order to ensure the reliability of the machine tool, the imported parts catalog is adopted for the key parts.
5. The bed, column, worktable, and gantry are HT250 casting structural parts, and the bracket is a rectangular tube welded part. Before processing, it is annealed at high temperature, and after semi-finishing, secondary annealing is used to remove stress, and then finishing is performed to ensure stable machine tool accuracy. ,The bed surface adopts the integral cast iron worktable to finely mill out the T-shaped groove, and the tabletop is CNC finely ground to ensure the accuracy of the worktable.
6. The power head spindle adopts precision spindle and is driven by servo spindle motor, which can be steplessly adjusted according to needs. The spindle can clamp drill taps or milling cutters through BT40 collets, and is equipped with a pneumatic tool cylinder to realize one-key tool change, with higher precision and high-speed cutting.
7. The machine tool is water-cooled, equipped with coolant supply, recovery and circulation system, and equipped with automatic oil lubrication system to ensure the smooth and long-term effective operation of linear guides and ball screws.
