Deep hole drilling machine INNSE BERARDI
FMM

The multi spindle machines Model FMM are used to perform the deep holes in the tube sheets for heat exchangers in Nuclear or Chemical plants.

The machine main features are :
• High dimensional hole accuracy
• Fully automatic drilling operations
• Complete monitoring of all drilling parameters as:
- oil delivery
- axial drilling thrust
- drilling power
• Dedicated drilling cycles
• Operator graphic support
• Customized fixturing design
• Elevating and safe operator platform

The multi spindle machines Model FMM are proposed with different number of spindle units, 2-3-5, and with different type of spindle unit movements:
• Common feed for all spindle units

• Independent feed for each spindle unit
The multi spindle drilling machines Model FMM can be used with two drilling systems :
• BTA System
• GUNDRILL System
On the machines with more than 3500 mm of vertical stroke , the longitudinal sliding (X-axis) is designed on hydrostatic oil bearing, to guarantee the max. rigidity and the best accuracy.
