MF1000/2F

IMSA GUN DRILLING/MILLING MACHINE

FOR MIDDLE-SIZE MOLDS AND BLOCKS

• The IMSA gun drilling and milling machine MF1000/2F is suitable for molds/blocks up to 6.5 tonnes (depending on the selected table configuration). A workpiece having a diameter as large as 1600mm can rotate inside the machine structure.
• MF1000/2F can be equipped with one of these tables:
  – standard rotary table size 800×1000 mm, load 4000 kg;
  – larger rotary table 1000×1200 mm, load 6500 kg;
  – rotary/tilting table size 1000×1000 mm, load 5000 kg, for compound-angle machining, with 360° rotation, 22.5…-22.5° tilting movement, both with radial resolution 0,001°.

• IMSA machining unit with separate spindles for deep hole drilling and milling, both optimized for their specific operation. Switching between the two spindles takes place automatically in 8 seconds via M function, without operator intervention.
• DEEP HOLE DRILLING. Drilling method: by gun drill tool. Drilling depth in single operation: 1000 mm. Deep drilling spindle, power 11 kW, 6000 rpm, for gun drilling Ø 4-25 mm, max. 32 mm counterboring or in short-chipping materials. This spindle is generally utilized to drill water lines in molds.

• Specific IMSA functions for deep drilling process control:
  – Electronic workpiece approach
  – Electronic check against gun drill breaking, by reading the cutting effort
  – Special coordinate transformation function for angled machining.

• Temperature, pressure and oil cleanliness are fundamental parameters to ensure continuous trouble-free gun drilling operations.
  For this reason the MF1000/2F is equipped with the best solutions that can automatically manage those three parameters to the most suitable value:
  – for oil supply to the gun drill: two different high-pressure pumps;
  – for oil clarification: a complete filtering system;
  – for oil cooling: a heat exchanger (chiller). The chiller is on a parallel oil circuit, and can be flexibly positioned around the machine.

• Chip conveyor as standard equipment.

• MACHINING: ISO40 milling spindle, power 13 kW, speed up to 6000 rpm. The milling head is positioned on the headstock, on top of the drilling slide, and is optimized for machining operations that prepare and complete the deep holes (spot facing, spade drilling, rigid tapping or thread milling). No intervention is required to switch from drilling to milling and back: operator attendance is not necessary.
• Automatic tool changer for milling head.

RIGIDITY AND CLEANLINESS:

• MF1000/2F has a vertical gantry structure, resulting in better rigidity: bending moment 4 times lower than in low-supported column structure, 16 times higher rigidity. The gantry column ensures the best performances all along the Y axis travel.

• This machine is conceived with a “shell-like” structure. That is, the MF1000/2F self-supporting structure integrates table and gantry column, and makes foundations unnecessary.

• A modern coverage encloses the whole machine, so that oil is contained inside the machine and cleanliness of the workshop area is ensured. The frontal door ensures spacious access for workpiece loading with hall crane or fork lift.
