On 15 June 2018, FERMAT’s dauntless film crew team travelled all the way to the exotic, mystical, faraway capital of Moravia, Brno, to record FERMAT’s new 5-axis continuous milling machine outfitted with rotary table and a brand-new servo-drive universal automatic milling head (UHAmi SDHS).

The video’s in finalization and post-production; it should be out in a few weeks.  In the meantime, here’s a crisp rundown of the machine, its construction, and outstanding attributes.

Machine Dimensions & Technical Parameters

The machine, a new-and-improved version of an earlier FERMAT model (FGU), has an X axis of 5 meters, Y axis of 3 meters, and a Z axis of 2.4 meters.  All 3 axes are built on linear guideways allowing a rapid traverse of 20 meters/min.

The headstock has no boring spindle; instead, it has a drive shaft transferring power from the 53 kW, water-cooled motor all the way down to the milling head.

The headstock is fully enclosed within a double column.  It moves along the Y axis on 4 linear guideways by means of two ball-screws (diameter 63 mm). Two servomotors with gear boxes turn the two ball screws on the column, actuating the headstock’s linear movement.

The machine column moves along Z axis on 2 linear guideways with 8 carriages. The movement is actuated by a ball-screw driven by a servomotor with gear box.

The rotary table can hold up to 20 metric tons. The table carriage moves on 3 linear guideways on a rack-and-pinion driven by 2 servomotors and gear-boxes, master-slave.  The table-top clamping plate rests on cross-roller bearing. 2 motors, master-slave, with planetary gear-boxes and pinions, power the rotary B axis. Once set, the table is locked in position by 4 hydraulic brakes.

All main components, such as headstock, column, beds, tables, head are designed and manufactured by FERMAT.

Ahead of the rest

The servo-drive universal automatic milling head (UHAmi SDHS) has a speed of 5,000 rpm, thanks to 12 bearings on the drive mechanism and an advanced form of lubrication.  The head can rotate ± 180° on 2 axes (A and C), driven by a total of 4 servomotors with pinions, 2 on each rotary axis, master-slave, that eliminates backlash. With the two servomotors, there’s no need to stop during positioning—and both axes, A and C, can be moved simultaneously, allowing uninterrupted, continuous milling.

The position of the milling head on both the A and C axes is measured by absolute rotary sensors with an accuracy of 0.001°.  When set in place and no rotating’s needed, A and C axes are locked in place by hydraulic brakes.
