Machine overview: IMSA MF1750EVO Gun Drilling and Milling Center

“GUNDRILLING AND MILLING IN SINERGY”: EVO-Series Gundrilling and Milling Center for molds that require multiple-axis waterlines.
IMSA Dual Spindle configuration: gun drilling spindle, tapping/milling auxiliary spindle. Long unmanned machining thanks to dual-spindle headstock. 45 kW - 4,500rpm - 430 Nm liquid-cooled milling spindle.
Drill-guiding steadyrests with IMSAUTOFOCUS system.
IMSA vertical gantry structure: column supported bottom and top.
Inductive scales provide top-level accuracy and repeatability. X axis 3,250 mm.
U-axis enables rotation of large molds into machine structure.
High loading capacity for compact table size (30 t - 1,600x 1,800mm in video).
4-side machining with an only workpiece setup on table. Inductive measuring system on table perimeter.
Best structural stiffness withstands forces in every position of Y axis.
Headstock W axis 600 mm. Milling quill Z axis 500 mm. Table overlap.
Optimized useable travel also when headstock is angled. New transmission with zero-backlash hypoid gearbox.
Demo machining:
Rough milling, 3 mm depth, Ø 80 mm cutter.
ISO50 tool storage (with 40 pockets in this video).
Contouring F5000, 0.5 mm depth, Ø 16 mm cutter.
Pocket milling: Ø 29.7 mm. Air nozzles outside tools.
Chamfering. Table overlap facilitates 4-side machining.
Tapping 38 mm depth, 1” NPT. Spindle effort 55% only. Oil nozzles outside tool.
Helical drill Ø 40 mm. Oil through milling spindle.
Full-automatic switchover between gundrilling and milling spindles. Electronic approach to workpiece. Gun drilling from Ø 5 to Ø 50 mm without pre-hole. Gun drilling spindle: 15 kW - 4,200 rpm.
Specific IMSA/HEIDENHAIN functions control the deep drilling process.
Long tool life thanks to structure rigidity and oil management.
