Equipped with a \u003cstrong\u003eSiemens PLC control with touchscreen\u003c\/strong\u003e, it allows for automated programming of grinding cycles, with adjustable feed rates and automatic return at the end of the program. The \u003cstrong\u003e405 x 1020 mm\u003c\/strong\u003e table, with a longitudinal travel of up to 1130 mm and a transverse travel of 450 mm, supports workpieces up to \u003cstrong\u003e600 kg\u003c\/strong\u003e thanks to the 400 x 1000 mm magnetic chuck. The servo-assisted vertical feed allows digital adjustments from \u003cstrong\u003e0.005 to 0.05 mm\u003c\/strong\u003e, while the Ø 350 mm grinding wheel and 4.0 kW motor ensure consistent power and precision. The reinforced cast iron structure, with a total weight of \u003cstrong\u003e3700 kg\u003c\/strong\u003e, guarantees rigidity and absence of vibrations.
