Description MF1250/2FL

IMSA GUN DRILL AND MILLING MACHINE

FOR MIDDLE-SIZE MOLDS AND BLOCKS

 

• The IMSA gun drilling and milling machine MF1250/2FL is suitable for molds/blocks up to 6 tons. A workpiece having a diameter as large as 1900mm maximum can rotate inside the machine structure. 1000x1000mm Rotary/Tilting table, infinite-position rotation movement, infinite-position ±22,5 degrees inclination.

• New liquid-cooled spindles.

• Drilling depth in single operation: 1250 mm. Deep drilling method: gun drill. 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.

• Straight drilling (3-axes machining), single-angle drilling (4-axes) and compound-angle drilling (5-axes machining thanks to rotary-tilting table)

• Specific IMSA functions for deep drilling process control:
  - Electronic workpiece approach
  - Electronic check against gundrill-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 MF1250/2FL 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.

• Auxiliary milling head ISO40, power 13 kW, 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 required for switchover gundrilling/milling and back. High-pressure oil (50 bar) through milling spindle. Automatic tool changer for milling head.

• MF1250/2FL 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 MF1250/2FL self-supporting structure integrates table and gantry column, and requires no foundations. The movable-column concept, compared with traditional movable-table structures, only occupies a compact area in the workshop while offering a wide horizontal machining travel. Floor panel included in standard machine configuration.

• 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.

* NEW in 2018-2019: Flex aluminum oil-proof front door. This new front door is more resistant and long-lasting in respect of the previous design with Lexan sheet.
