SINGLE-SPINDLE
GUN DRILL TOOL AND BTA/STS TOOL
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 /76 GDK: 1000 mm
- MFTB 2000 /76 GDK: 2000 mm
- MFTB 3000 /76 GDK: 3000 mm
- Hole diameter range: 8 – 76 mm:
- with gundrill tools, solid: 8 – 25 mm
- with BTA tools, solid: 20 – 76 mm
- drill tube max: 63 mm
- drilling dia. in counter boring: 85 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 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 …/76 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 multilevel filtering system;
– for oil cooling: a heat exchanger.
