Serving increasing demand for precision and reliability with grinding solutions
Hartmut von Fugler
Particular precision and process reliability have characterized automotive engineering for many decades. With the establishment of e-mobility, however, these demands are increasing once again, because many e-motor components need to be manufactured even more "perfectly."
In most cases, this involves the highest surface finish in the micrometer range so that no loud running noises occur on the gear components. In a quiet e-motor, for example, these noises would be audible.
In this context, the technology of EMAG SU is drawing the attention of many production planners. Among other things, the specialists developed highperformance solutions for gear grinding - including short chip-to-chip times, intelligent axis concepts, thermal and mechanical stability, and a high degree of user-friendliness. Which machines and processes are the focus here?
Outstanding solutions for the field of gear profile grinding include the G 250 machine and the G 160. The G 160 is used for components up to module three and with a maximum O/D (outer diameter) of 160 millimeters. It is considered the fastest machine on the market for this application, thanks to two parallel workpiece tables that alternately move to the grinding wheel at high speed.
The larger G 250 machine also scores with precision, minimal chip-to-chip times and short setup times.
The G 250 achieves a comparably high productivity level when machining pinions with a strong crowning in the tooth flank profile and normal crowning in the flank line. In addition, energy consumption is massively reduced. The whole thing is made possible by a dual-tool system with two different tool spindles in the machine: one for finish-machining by hobbing and one for finish-machining by grinding.
"You could certainly say that we guarantee our customers competitive advantages and a fast return in investment," says Alexander Morhard from EMAG SU. "To this end, we continuously invest in research and development to further increase the efficiency and environmental friendliness of the machines. The result is perfect solutions for the production of ultra-fine surfaces with different contours."
