Crankshaft Machines

UH - series

The UH series stands for highest productivity in the mass production of large crankshafts and other rotary workpieces. The modularly designed machines are characterized by high stability and precision accuracy as well as consistent quality with maximum availability. The UH series can also be used for machining other rotary workpieces such as camshafts, connecting rods and common rails of passenger car, commercial vehicle and large industrial engines.

Description

  • UH 700 for passenger car crankshafts (up to V12)
  • UH 1500 for commercial vehicle crankshaft machining
  • UH 2500/3000 for crankshaft up to 3000 mm
