Details and advantages

1. The drilling machine is mainly composed of bed, CNC sliding table (3), drilling spindle (3), clamping device, detection device, cooling system, scrap iron box, etc.
2. There are three CNC sliding tables, which are fixed side CNC sliding table, mobile side CNC sliding table and middle CNC sliding table. The three sliding tables are composed of sliding plate, sliding table and servo drive system. There are six CNC axis on the three sliding tables, including three feed CNC axes and three positioning CNC axes. Each CNC axis is guided by precision linear rolling guide and driven by AC servo motor and ball screw, which ensures its positioning accuracy.

7. The machine is equipped with beam width detection and web height detection device, which can effectively compensate the deformation of the beam and ensure the machining accuracy; The two kinds of detection devices adopt the wire encoder, which is convenient to install and reliable to work.
8. The machine adopts the trolley feeding, and the CNC clamp feeding mechanism is composed of servo motor, gear, rack, detection encoder, etc.
9. Each spindle box equipped with its own external cooling nozzle and internal cooling joint, which can be selected according to the needs of drilling. Internal cooling and external cooling can be used separately or at the same time.
