According to Samputensili, the G 160 features a new concept for the high-productive grinding of gears up to 160 mm in diameter with double work spindles. As is explained, separate X1 and X2 axes, driven by linear motors, replace the typical rotary turret. This concept is claimed to allow a faster workpiece change and a chip-to-chip time of less than 2 seconds including meshing, synchronization and simultaneous repositioning of the tool. A further advantage of the machine is that no additional axis is needed to perform the dressing cycle. The dresser is mounted on the X1 axis slide next to the workpiece spindle. As a result, the precise and highly dynamic motion of the linear motor can also be used to fine-tune the geometry of the grinding wheel and the corresponding gear. This enables topological modifications of the gear flank at a very high quality. As the manufacturers point out, having the dresser located on the same slide as the workpiece spindle makes it totally insensitive to thermal or other types of deviations.
Wet grinding machine with new axis concept
Samputensili will be unveiling the new G 160 gear generating machine for the first time at a European trade show. This wet grinding machine is reportedly characterized by a unique machine structure that is designed to optimize dynamic stiffness in comparison to current standard machine architectures.
