1ES/3ES
 The traditional heavy and rigidity of CMU machines are above all kept in synchronized press brakes so that limit flexion and to bear heavy working load, heaving high bending precisions. The heavy monolitic frame along with strong dimensioned shoulders, is taken together in the bottom by the bed and a boxsheet, in up side by box-sheet containing a tank oil, forming an unic rigid structure. Bed is completed of a manual crowing to adjust bed flexion and eliminate shimming and a raceway take matrice. On the ram is plated a big orizzontal beam with adjustable screws, and the tool intermediaries with adjustable wedges, to adjust any ram flexions. Duty pre-lubricated slidiways and an additional manual grease lubrication are keeping the ram all the time well guided. The CMU hydraulic system is at 3 level of security. The pump is with high performances and at low level of sonority. The CNC electronic programmers is alphanumeric type or on request bidimensional coloured graphic screen, or tridimensional able to adjuste from 3 to 13 axes. The back gauge, - is interly designed and made in home. It is a multiaxes back gauge and can arrive till 6 axes (X - X1+X2 - R - R1+R2 - Z1+Z2). It is placed on the side shoulders, made by heavy dimensioned components at ball screws. Electrical board made in according to the CE regulation and at low tension of 24 volts. The DNC programmer and board buttons are placed on a box-sheet taken by a side mobil arm.
High precision performances:
- cylinders parallelism: Y1+Y2 = ±0,01 mm (± 0,0004”) -
back gauge: axe X = ± 0,1 mm (± 0,004”) axe R = ± 0,2 mm (± 0,008”)
- back gauge speed: axe X = 300 mm/sec. axe R = 120 mm/sec.
Serie 1ES
With the oleodinamic cylinders placed on a bottom flange and fixed on front of the shoulders, are dimensioned for presses from 300tons upper.
Serie 3ES
With the oleodinamic cylinders placed on the
front of the shoulders, are dimensioned for presses till 250tons..
