1 There are six CNC axes 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.
2 Each spindle box can be drilled separately or at the same time.
3 Equipped with BT40 taper hole, it is convenient for tool changing, and can be used to clamp twist drill and cemented carbide drill. The performance of drilling and tool changing is stable, and it has a wide range of applications. The speed can be continuously variable in a large range to meet a variety of speed requirements。
4 The material is fixed by hydraulic clamping. There are five hydraulic cylinders for horizontal clamping and vertical clamping respectively.
5 In order to meet the processing of multiple hole diameters, the machine is equipped with three in-line tool magazine, each unit is equipped with a tool magazine, and each tool magazine is equipped with four tool positions.
6 The machine is equipped with material width detection and web height detection device, which can effectively compensate the deformation of the material and ensure the machining accuracy;
7 The machine adopts the trolley feeding, and the CNC clamp feeding mechanism.
8 Each spindle box is equipped with its own external cooling nozzle and internal cooling joint, which can be selected according to the needs of drilling.
