GDC Gantry Type Series (Bridge Plate)

Code pro010

CTR 622


  1. GDC-4000 with high speed spindle up to 2000rpm, support cooling thru spindle & rigid taping for heavy duty drilling & high efficiency.
  2. GDC-4000 is gantry type high speed drilling machine, it’s suitable for large dimension plate drill job, such as steel structure bridge plate.
  3. Drilling diameter from 6~50mm, this machine also can apply in most usage of steel construction, joint plate, heat changer tube plate drilling job.
  4. Rigid BT40 taper spindle, with spindle air cooling system & air positive pressure system to protect the spindle.
  5. CNC system: Dama-Syntec Special purpose CNC system, Windows CE base for plate drilling jobs with ease operation interface.
  6. Provide alignment function, plate no need parallel with guide rails also can execute the drill jobs.
  7. Provide the hold-down mechanism to keep work part stable before drilling.
  8. Max drilling thickness up to 100mm, users can load many plates as layers & drills in one term while drill small piece joint plate.
  9. Standard 12T umbrella type ATC with tool life management, users can set up the max Z feeding distance, once over the setting value, the machine will change the tools automatically.
  10. Longitudinal axes (2 sides ) with Auto clamping device, they will hold & clamp the machine body tightly during drilling & enhance the machine satiability.
  11. File transfer software (DXF to G.M code) , part program easy produce.
