The Innse-Berardi multi spindle drilling machines model FMM are used to perform the deep holes in the tube sheets for heat exchangers in Nuclear and Chemical plants. The FMM machines are proposed with 2-3-5 spindle units either with common or independent feed and adjustable pitch.

Both BTA and GUNDRILL systems are provided. On the machines with high vertical stroke the longitudinal sliding (X-axis) is designed on hydrostatic oil bearing to guarantee the max rigidity and the best accuracy.
