GT1818/3 CNC boiler barrel drilling machineI .Machine application:Mainly used in drilling of boiler drum and similar workpiece , with working capacity ,9 Meters workpiece ,max drilling dia. 1800mm.II .Machine structure and Mechanism This machine includes the following parts : Machine bed I.Designed to carry the head and end of machine bed ,slipway,under support. And the head & end of the bed equipped with hydraulic chuck to clamping workpiece;Machine bed IIDesigned to carry the longitudinal slide carriage , drilling head, hydraulic slipway, fore clamping pressure device , used to install drilling device; Besides that, it also includes back support, chip collector & cooling, hydraulic system, electrical system, Laser alignment device etc. 1. NO. I Machine is mainly used to carry the workpiece .On side of machine body , installed fixed bed head , and on the upper surface installed two Rectangular guideway , which will realize the sliding of bed back and bottom support . Installed hydraulic pressure three jaw chuck on the bed head and back separately , to center locating clamp of boiler drum with clamping dia. range 200 -1800 mm; installedlifter on the back support for saving workpiece during working . The longitudinal moving of bed back will realize working of 2-9m boiler drum . On the head of machine body, installed CNC scale division facility , realize the rotation scale division on the range of ±180 degree. 2.NO. II Machine is mainly used to carry the longitudinal moving of drilling. Equipped with three independent drilling head , its moving relies on the longitudinal slide carriage, hydraulic slipper on the NO. II machine , with hydraulic lock . Drilling head can realize stroke control automatically by hydraulic slipper and automatic exchanging of fast infeeding, working infeeding, fast back . Through adjust the blot space of contactless switch ,it Can also be achieved automatically stop when the drill bit in the end of the drilling exit a certain distance,
