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


  • The IMSA deep hole drilling machine MFT 1000EVO is dedicated to cylindrical workpieces that have to be drilled on their rotation axis. Drilling depth in single operation: 160x diameter until a maximum of 1000mm. Hole diameter range 4 – 25 mm. Some applications: transmission shafts, gear shafts, lubricators, valves, in general all round workpieces that have to be drilled on-center.
  • Deep drilling method: gun drill tool. Drilling spindle: 9 kW, 6.000 rpm.
  • 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 MFT 1000EVO deep hole drilling machine is equipped with the best solutions that automatically manage these three parameters to the most suitable value:
    – high-pressure pump managed by inverter;
    – for oil clarification: a complete 3-level filtering system;
    – for oil cooling: a heat exchanger (chiller).
  • The MFT 1000 EVO version manages oil pressure and flow though inverter; moreover this EVO version enables a very quick setup thanks to full-cnc movements.


  • Workpiece automatic loader,
  • Small diameter adjustment to drill Ø 3 – 20 mm,
  • Large diameter adjustment to drill Ø 6 – 32 mm,
  • Drilling diameter increase up to 32 mm,
  • Automatic door opening,
  • Steadyrest for workpiece support,
  • Automatic 3-jaw chuck.


Drilling diameter range min-max: 4 – 25 mm.
Drilling depth 160xD, max. 1000 mm.
Workpiece counter-rotation 150 rpm.
Workpiece locking: by CNC.
Drilling spindle 9 kW – 6000 rpm.
Oil pressure max. 80 bar.


Axial deep drilling of custom sized cylindrical parts

Two I.M.S.A. MFT deep drilling machines, supplied to corporate clients this year between June and July, feature some improvements which the manufacturer highlights by adding the code EVO to the machine name. One model was built for a French tool manufacturer, while the other one was developed for an Italian company operating in the aeronautical field.
