The portal machining centre VPC-U displays its entire strength in 5-side machining of workpieces with its tilting spindle and the rotary table integrated into machine bed. The spindle swivels around the Y-axis while the NC-rotary table turns the workpiece into the right position in line with the specifications. The complete machine table consists of a combination of fixed tables and rotary table that is set higher than the fixed tables for the horizontal machining.

Traverse ranges:

X = 2300 mm - 3400 mm (vertical)
X = 2000 mm - 3100 mm (horizontal)
Y = 1200 mm - 2200 mm
Z =   600 mm - 1100 mm

 

  • Main design

    Main design

    • Extremely rigid, static and dynamically well balanced ground frame construction
    • Spacious and easily accessible machine tables
