Mass-Centering Machines for Crankshafts 400 SBRZ, 600 SBRZ, 400 MBRZ

Modular design, change over for various crankshaft types through different carriages
Fully automatic operating sequence
Direct integration with production lines
Processing of unbalance data from the final balancing machine for optimization of the manufacturing process

Design

Mingle or multi-station machines with automatic sequence. Loading and unloading manually with a suitable lifting device, automatically by loading gantry or by integrated lift and carry transport.

Flexible machine design, especially suitable for varying crankshaft programs. Manual or automatic length
adjustment for change-over to various crankshaft lengths. Balancing frame supported on the machine base by round springs. Two carriage units mounted on the balancing frame with integrated externally rotating end discs mounted on precision bearings, each with two adjusting gears. Hydraulic spindle drill units or electro-mechanical carriage drill for center drilling, either integrated into the measuring station or arranged in a separate centering station.
