400 SBRZ, 600 SBRZ, 400 TBTZ, 400 MBRZ Mass-Centering Machines for Crankshafts • 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 Range of application Mass-centering of face milled raw crankshaft castings or forgings in a variable program. Processing of symmetrical and asymmetrical crankshaft types by change over. Conceived for use by engine manufacturers in mid-volume and high-volume production. Manuel loading and unloading of the machine by lifting device or automatically by interfacing with customer's conveying equipment. Integration of preceding or subsequent process steps in the complete line. 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.

400 SBRZ, 600 SBRZ, 400 TBTZ, 400 MBRZ Mass-Centering Machines for Crankshafts Measuring station for determining mass eccentricity by dynamic unbalance measurement. The crankshaft is loaded and unloaded from above, clamped at the main journals and driven between synchronous-rotating end discs by an amply dimensioned drive unit. Clamping and setting elements are easily exchanged for various crankshaft lengths. Adjuster gear with drive through separate stepper motors. Processing of asymmetric crankshafts by offset of the measuring unit.Single-station machines are equipped with integrated...
