China CNC Gantry Moving High-Speed Plate Drilling Machine

Applicable Industry:
Mainly used for drilling tube plate, clapboard, flange and large plate in petrochemical, boiler, wind power, flange industries and also for connection plates in building, bridge, heat exchange, iron tower industries.
Product feature:
1. The machine consists of work table, gantry, slide carriage, power head, CNC system, cooling chips discharge system etc.
2. The machine works in mode of work table being fixed and gantry moving.
3. The gantry and work table are weld assembly, which was high temperature annealed before processing, was annealed again after half finished machining to remove stress, then finished machining so that ensure stable precision.
4. The machine has 3 numeric control axes; The gantry can make longitudinal movement along the guide(X axis); the power head can make lateral movement along the guide (Y axis).
5. The power head spindle is precision spindle of Taiwan KENTURN , which is driven by special frequency conversion motor and can make stepless speed regulation according to needs. The spindle is BT50 taper hole. The drilling head, reamer or milling cutter can be installed by splice bar. The spindle box has a loose cutter cylinder (air and hydraulic pressure) for easily changing cutters. It also can equip with cutter inter-cooled splice bar to realize high speed cutting.
6. The chip cleaner equipped beside of work table can discharge chips automatically. The drilling use water cooling with the system of cooling liquid providing, recycling, circulating and filtrating.
7. Numerical control uses FAGOR8055 system, with RS232 connector and LED monitor.
8. Protective covers are equipped for X/Y axis guides and lead screw of the lathe. Iron sheet cover is for X axis, and organ-protective cover for Y axis.
9. For ensuring the reliability of the machine, the key components use high quality imported products. See the main spare parts list for details.
