Producing Gears in the Shortest Possible Time: G 160 Gear Generating Ginding Machine from EMAG SU
The G 160 gear generating grinding machine splits the X-axis of current machines into two linear slides (X1, X2), each of which carries one workpiece spindle.
So both work-spindles are under full position control anytime. Being driven by high dynamic 30 m/s linear motors, changing spindles comes down under 2 seconds including simultaneous repositioning of the grinding wheel. The machine architecture with only three axes instead of 4 axes concept of current machines, is a breakthrough.
The tangential axes are not in the machine and will be created by an interpolation of Z-Y-axes. This stiff machine concept ensures the best production times on the market. The increasing demａnd on efficiency and noise emission of the gears pushes the grinding process to its limits. The stiffness and stability of a gear generating grinding machine is the main design target for such a high dynamic process, and the G 160 presents a unique design to optimize the dynamic stiffness compared to current standard machine architectures.
