GT Series boiler drum CNC drilling machine
GT series gantry moving CNC boiler drum drilling machine is mainly used for drilling of boiler drum parts and similar parts in the boiler industry.
Can use special carbide tools to complete the drilling and welding groove processing at one time.

1.The headstock is made of high-strength cast iron with resin sand molding and reasonable reinforcement structure, with good rigidity and strong stability.
2.The CNC indexing head is fixed to one end of the machine base.The precision rotary support is adopted, and the CNC indexing is realized by the servo motor through the precision planetary reducer.The indexing head is fitted with a three-jaw self-centring chuck, which allows easy clamping and unclamping of workpieces and reduces the labour intensity of workers.
3.Each gantry is driven independently, and the number of gantry can be determined according to customer requirements.
4.The power head of CNC boiler drum drilling machine is strengthened at the weak link through finite element analysis to make the structure more reasonable.
5.The imported spindle group with excellent quality is selected, which has super large torque output capacity, and the spindle is in the form of synchronous pulley.
6.The boiler drum support frame adopts two kinds of lifting support frame and fixed support frame. When rotating, lift the support frame to lift the workpiece, and fall on the fixed support frame during processing to prevent the workpiece from slipping.
7.The CNC system adopts German Siemens 840D or 2 sets of 828D system, and is equipped with RS232 interface and LCD liquid crystal display. The drilling coordinates can be directly converted from CAD/CAM, and it is also equipped with the pre-drilling vacancy rehearsal and recheck function, which is very convenient to operate.
