Brains and Brawn

In combining the strength of an immense, oversize CNC floor-type horizontal boring machine with one of the most precise universal micro indexing automatic milling heads on the market, FERMAT created a machine tool able to perform an array of machining techniques in extremely fine detail.  FERMAT’s in-house universal micro indexing automatic milling head (UHAmi 30), with indexing of 0.001°/0.001°, high precision bearings, ground gears, and speed up to 3,000 rpm provides excellent machining both inside and outside of any large or small workpiece.

All of FERMAT’s horizontal boring machines, even the large, massive ones are not only capable of powerful and heavy cutting but also detailed and precise work.  A machine test of FERMAT’s WRF 160 CNC using FERMAT’s custom-designed universal micro indexing milling head equipped with a vertical face milling tool and also a side milling tool, known as a “porky” cutter (porcupine milling cutter), can be seen here chewing away at an old-style milling head, executing light, exact face milling and circular interpolation :

When the cutting is less glamorous and more rough and rugged, you can take off the gloves and utilize the hard-hitting power of FERMAT’s top-of-the-line, heavy duty floor type boring mill, WRF 160 CNC, with ram stroke of 1,200 mm, spindle extension of 1,000 mm, and spindle diameter of 160 mm.  This monster horizontal boring machine is perfectly engineered for machining heavy or bulky workpieces, especially when equipped with its own FERMAT-designed rotary table that is incredibly precise, with no stick-slip problems, and boasts a herculean load bearing capacity.

Like all of FERMAT’s CNC horizontal boring machines, the ram for WRF 160 CNC is made of ductile iron, toughened and strengthened through annealing.  Its accuracy is enhanced using ball screws and linear positioning scales, ensuring perfect alignment even when milling difficult and punishing workloads.  The column is uniquely constructed for the utmost rigidity and firmness, allowing maximum power and precision throughout all machining techniques.
