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.
Design
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.
