Estimated price range
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 NGM is a five-axis tool grinding machine defined by its options: two grinding spindle ratings, ball screw or linear motor axis drives, a wheel loader in two capacities and robot loading from three pallet arrangements. Travels are 500 mm in X, 400 mm in Y and 380 mm in Z. Maximum tool diameter is 300 mm, maximum cutting length 300 mm and maximum workpiece length 500 mm, and the machine weighs 7000 kg.
The grinding head is a double ended, direct-drive spindle with HSK 50 or HSK 80. Schneeberger gives two power ratings: 10 kW (100 %) and 13 kW (60 %), or 24 kW (100 %) and 32 kW (60 %). A peak of 82 kW is listed too, without saying which spindle it belongs to, so ask for the power curve of the spindle being quoted. The larger rating is the one to specify when the work is fluting from solid toward the top of the diameter range.
Linear axis resolution is given as to 10 nm, with recirculating ball screws or linear motors as the axis drive. The A axis is an ISO 50 tool carrier and the C axis gives 380° rotation of the grinding head; both resolve 0.0001°. Because the head turns slightly more than one full revolution, either end of the double ended spindle can be brought to the tool. The control is a FANUC 31i-B5 with 5 controlled axes.
Automation covers both the tools and the wheels. A Fanuc robot loads from 2 pallets, 4 pallets or a stack with 10 pallets, each 300 x 300 mm. The wheel loader has 8 or 14 positions for 24 or 42 grinding wheels, so a mixed batch of tool types can run without anyone re-fitting the spindle between them.
Below it in the range, the Aries NGP has 420 mm, 360 mm and 260 mm of travel, an HSK 50 spindle of 5 kW (100%) and a weight of 1,700 kg (3,747 lb).

Strengths & Limitations
Strengths
- Two grinding spindle ratings to choose from: 10 kW (100 %) and 13 kW (60 %), or 24 kW (100 %) and 32 kW (60 %)
- Wheel loader with 8 or 14 positions for 24 or 42 grinding wheels
- Fanuc robot loading from 2 pallets, 4 pallets or a stack with 10 pallets, each 300 x 300 mm
- Linear axis resolution to 10 nm and 0.0001° on both the A and C axes
- C axis gives 380° rotation of the grinding head, more than one full revolution
- Takes tools up to 300 mm in diameter and workpieces up to 500 mm long
Limitations
- Maximum cutting length is 300 mm even though workpieces up to 500 mm long fit, so long-fluted tools are outside its range
- At 7000 kg it needs floor and rigging planning that the 1,700 kg (3,747 lb) Aries NGP does not
- Spindle rating, HSK size, axis drive, wheel loader size and pallet arrangement are all choices, so two machines of this model can differ widely
- The 82 kW peak figure is listed without the spindle option or the duty it applies to

Frequently Asked Questions
01
The grinding head is a double ended, direct-drive spindle with HSK 50 or HSK 80. Power is 10 kW (100 %) and 13 kW (60 %), or 24 kW (100 %) and 32 kW (60 %). Schneeberger also lists 82 kW peak but does not tie that figure to one of the two ratings.
02
The wheel loader comes with 8 or 14 positions, for 24 or 42 grinding wheels. Which size a machine has is a build choice, so check it against the number of wheel sets your tool families need before assuming the larger one.
03
By a Fanuc robot. Schneeberger lists three arrangements: 2 pallets, 4 pallets or a stack with 10 pallets. Each pallet measures 300 x 300 mm. The A axis that receives the tool is an ISO 50 tool carrier.
04
Maximum tool diameter is 300 mm, maximum cutting length is 300 mm and maximum workpiece length is 500 mm. The axes travel 500 mm in X, 400 mm in Y and 380 mm in Z, and the grinding head rotates through 380° on the C axis.
05
Either. The axis drive is listed as recirculating ball screw or linear motor, and linear axis resolution as to 10 nm. Since the drive type is a build choice, it is one of the first things to confirm on a quotation or on an existing machine.
06
Size, power and weight. The Gemini NGM travels 500 mm, 400 mm and 380 mm and weighs 7000 kg, while the Aries NGP travels 420 mm, 360 mm and 260 mm and weighs 1,700 kg (3,747 lb). The Aries NGP has one HSK 50 spindle of 5 kW (100%); the Gemini NGM offers HSK 50 or HSK 80 and up to 24 kW (100 %).
