Our best estimate for a cnc grinding machine in this class — not a quote from Schneeberger. Configuration moves it a long way.
Overview
The Schneeberger Gemini, going by the listed figures, is a five-axis grinder with two operating modes: tool grinding and cylindrical/form grinding. The pairing is what separates it from a pure tool grinder. On paper a blank can be ground round or to a profile and then have its cutting geometry ground in the same clamping. The plain Gemini is not in Schneeberger's current lineup. It is a different entry from the Gemini NGM, whose table gives 500 mm, 400 mm and 380 mm of travel and a weight of 7000 kg.
For tool work the range is 1 to 40 mm in diameter with a maximum grinding length of 320 mm. The grinding head has three spindles and indexes automatically, runs up to 10,000 RPM and is rated 9 kW. Three spindles matter more on a dual-mode machine than on a tool grinder, since cylindrical wheels and fluting wheels have to be mounted at once.
Positioning accuracy is given as ±0.001 mm and repeatability as ±0.0005 mm, on a thermally stabilized granite composite base. In-process gauging is optional, and for the cylindrical mode it is the option to look for, because without it diameters are held by the axes alone. The control is listed as Fanuc with Schneeberger MARS software. Wheel sizes, axis travels and weight are not among the listed figures.

Frequently Asked Questions
01
The listed operating modes are tool grinding and cylindrical/form grinding. With both on one machine, the round or profiled body of a tool and its cutting edges can in principle be ground without re-clamping, which removes one source of runout between the two.
02
A tool diameter range of 1 to 40 mm and a maximum grinding length of 320 mm. The grinding spindle is listed at 9 kW and up to 10,000 RPM, on a 3-spindle head with automatic indexing.
03
No, the listed figures mark in-process gauging as optional. If cylindrical grinding to size is the reason for buying, confirm that the gauge is fitted. Listed positioning accuracy is ±0.001 mm and repeatability ±0.0005 mm.
04
The two have separate tables and should not be mixed up. The Gemini NGM is listed with 500 mm, 400 mm and 380 mm of travel, HSK 50 or HSK 80, spindle power from 10 kW (100 %) and a weight of 7000 kg, while the listed figures for the plain Gemini give a 9 kW spindle and no travels or weight.
