Gemini NGM

Gemini TAP


Gemini GHP


gemini NGM represents a large grinding volume in a compact machine with efficient automation. The possible configurations range from high-powered flute grinding to profiling of hobs with high-frequency relief grinding. Generous axis travel don’t just cover the workpiece dimensions, but allow plenty of space to include processes such as dressing, measuring and loader access.

Remarkable features of the gemini NGM are power, mechanical and thermal stability and absolute precision. The dynamically relevant axes can be configured with linear motors, supporting oscillating processes or the rapid change over of auto loading or dressing processes rendering the work effortless.

Thanks to the compact machine design, the high-performance gemini NGM is also highly efficient. The robot compartment is located very close to the tool holder. Tools are changed reaching through the rapid collapsing doors in seconds. The loader space can be conveniently observed from the outside. The swiveling control console allows accessibility to make loading or creating production jobs easier all around. The wheel magazine for 8, 14 or 24 wheel packages with wheels of up to 250mm (10″) in diameter offers absolutely no limit for designing complex grinding processes.
