Emag’s innovative grinding solutions are revolutionizing the gear manufacturing industry. With their advanced G series gear-profile grinding machines, Emag offers unparalleled precision and efficiency. The G 160 and G 250 models, in particular, have set new standards for gear-profile grinding.
The G 160 Gear-Profile Grinding Machine
The G 160 is designed for components up to module three with a maximum outer diameter (OD) of 160 mm. It boasts two parallel workpiece tables that move alternately at high speeds, allowing for continuous operation as one component is machined while the other is loaded or unloaded by an internal robot. This model eliminates the need for a tangential axis by using simultaneous Y- and Z-axis movements to create a “virtual” tangential axis, ensuring minimal ghost frequencies on the component surface.
The G 250 Gear-Profile Grinding Machine
For larger components with a maximum length of 550 mm, the G 250 steps in with its double table design, similar to the G 160. It features minimum chip-to-chip times, short setup times, and a rigid design that prevents thermal growth during operation. The G 250 can retool for different processes in minutes and supports Emag’s “Sky Grind” process, which allows for dry grinding without the need for coolant.
Comparative Table of G 160 and G 250
| Feature | G 160 | G 250 |
|---|---|---|
| Max Component Size | OD 160 mm | Length 550 mm |
| Tables | Two parallel workpiece tables | Double table design |
| Axis Movement | Virtual tangential axis | Standard axis movement |
| Grinding Process | Simultaneous Y- and Z-axis | Main grinding spindle |
| Special Feature | Prevents ghost frequencies | Supports “Sky Grind” dry grinding |
Emag’s gear-profile grinding machines, particularly the G 160 and G 250, offer high-speed, precision grinding with innovative features that enhance productivity and quality. Their intelligent design concepts and thermal stability make them a top choice for manufacturers seeking to optimize their gear grinding processes.
