MFT 750 /6 CR


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


  • The deep hole drilling machine IMSA MFT 750/6 CR is dedicated to workpieces up to 750mm, that have to be drilled on their rotation axis for diameters from 1,5 to 6 mm. A typical application is the medical industry.
  • Deep drilling method: gun drill tool. Drilling depth in single operation: max. 120 mm from dia. 1,5 to 3 mm (40-50 times the diameter); max. depth 750 mm (160 times the diameter) from dia. 3 to 6 mm. Drilling spindle 5,8 kW, 15.000 rpm, liquid-cooled.
  • The workpiece is in counter-rotation in respect to the gun drill, in order to obtain the maximal drill straightness and process speed. Counter-rotation 150 rpm.
  • Specific IMSA functions to control the deep hole 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. MFT 750/6 CR is equipped with the best solutions that automatically manage these three parameters to the most suitable value:
    – for oil supply to the gundrill: two different high-pressure pumps;
    – for oil clarification: a complete two-level filtering system;
    – for oil cooling: a heat exchanger (chiller).



  • Workpiece automatic loader,
  • Controlled CR head movement,
  • Automatic door opening,
  • Automatic chip conveyor,
  • Steadyrest for workpiece support,
  • Digital pressure measurement.
