A new generation of giants

FERMAT’s series of colossal floor-type horizontal boring mills has just beefed up and cut the fat.  With an even stronger build and a firmer design, the new-and-improved heavyweight champions need less headroom and can reach farther down to strike terror at ground level.

FERMAT’s clever cabal of machine tool designers came up with a hefty answer of slapping two 100 mm-diameter ball screws onto the Y axis.  Each ball screw is turned by its own powerful, water-chilled motor connected to a right-angle gearbox that reduces the machine’s height without compromising vertical travel of the headstock.

With such great motors and gearboxes, the team threw them also onto the X axis, allowing the headstock to travel even lower than before, by 300 mm.  The rapid traverse along the X axis is 40 meters/minute.

Not satisfied with just motors, gearboxes, and ball screws, the craftsmen added new telescopic covers to the X axis that smoothly slide over each other, contributing to a higher maximum speed of column travel.  Then, they decorated the front and back of the column with new, snazzy shutter covers which take up less space than the earlier guillotine ones.

The machine’s ram, built on linear guideways, is 1.5 meters long.  And, as an option, this new generation of WRF floor-type horizontal boring mills (2G) can come with a tilting headstock (0° to -8°), with its accuracy guaranteed by a rotary sensor and locked in place by hydraulic brakes.
