Cnc Deep Hole Drilling Machine for cylindrical parts, on-center holes



  • The deep hole drilling machines of the IMSA Series MFTB are dedicated to cylindrical workpieces that have to be drilled on their rotation axis.
  • Deep drilling method: in the intermediate diameter range between the Gun Drilling and the BTA Drilling, we propose a Double-Setup flexible solution we called IMSA “GDK” System. Our machines of the GDK Series work with 2 different deep drilling methods: BTA tool and Gun Drill tool. This enables you to better take advantage of both tool types.
  • Drilling depth in single operation:
    • MFTB 1000 /51 GDK: 1000 mm
    • MFTB 1500 /51 GDK: 1500 mm
    • MFTB 2000 /51 GDK: 2000 mm
  • Hole diameter range 8 – 65 mm:
    • with gundrill tools, solid: 8 – 24 mm
    • with BTA tools, solid: 18 – 51 mm
    • drill tube: 51 mm
    • drilling dia. in counter boring: 65 mm
  • The workpiece is in counter-rotation in respect to the gun drill, in order to obtain the maximal drill straightness and process speed.
  • Specific IMSA functions to control the deep drilling process:
    – Electronic check of cutting parameters,
    – Double electronic check against gundrill-breaking, by reading the cutting effort.
  • Temperature, pressure and oil cleanliness are fundamental parameters to ensure continuous trouble-free gun drilling operations. The IMSA MFTB …/51 GDK deep hole drilling machines are equipped with the best solutions that automatically manage these three parameters to the most suitable value:
    – high-pressure pumps with inverter;
    – for oil clarification: a complete 3-level filtering system;
    – for oil cooling: a heat exchanger.


  • Automatic door opening at workpiece side,
  • Workpiece loader,
  • Automatic chip cleaner.
