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 Sirius is a five-axis tool grinder in the listed figures, covering tool diameters of 1 to 32 mm and a maximum grinding length of 280 mm. A model under the plain name Sirius is absent from Schneeberger's current lineup, so anyone weighing a machine offered under it should look first at two rows of the table: probing and loading.
In-process probing is an optional integrated probe. Loading is described as robot loading compatible, which is an interface and not a loader. Neither row says that a machine has a probe or a robot. A machine with both can be set up to run unattended and to measure between tools; a machine with neither is a manually loaded grinder that relies on the operator to measure. Ask which it is before anything else.
The grinding head has two spindles with automatic indexing, running up to 10,000 RPM on 7.5 kW. Two wheel positions cover a roughing and a finishing pack, but a tool needing a third wheel set means a changeover. The base is thermally stable granite composite, with positioning accuracy listed as ±0.001 mm and repeatability as ±0.0005 mm. The control row reads Fanuc with Schneeberger MARS software. For scale, the Aries NGP is listed with an HSK 50 spindle of 5 kW (100%) and the Gemini NGM with 10 kW (100 %) or 24 kW (100 %), which puts the 7.5 kW here between the two.

Strengths & Limitations
Strengths
- Listed as robot loading compatible, so a loading robot can be added through the automation interface
- Optional integrated probe for in-process probing
- 2-spindle grinding head with automatic indexing, 7.5 kW and up to 10,000 RPM
- Thermally stable granite composite base, with repeatability listed as ±0.0005 mm
Limitations
- The integrated probe is optional and the robot is not part of the machine, so automation depends on how the machine was equipped
- Only two grinding spindles on the head; tools needing a third wheel set require a changeover
- Tool diameter ends at 32 mm and grinding length at 280 mm

Frequently Asked Questions
01
Not as listed. The automation row says robot loading compatible, meaning the machine can work with a loading robot, not that it includes one. On an existing machine, check whether a robot was supplied and whether the interface is installed and working.
02
No. In-process probing is listed as an optional integrated probe. Without it, tool position and ground dimensions are checked outside the cycle, so confirm whether the probe is fitted if unattended running is the plan.
03
The listed tool diameter range is 1 to 32 mm and the maximum grinding length is 280 mm. Those limits define the machine as a grinder for small and medium shank tools; larger cutters and long tools fall outside the listed range.
04
Two, on a head that indexes automatically. Spindle power is listed at 7.5 kW and spindle speed at up to 10,000 RPM. With two wheel packs mounted, a typical sequence of roughing and finishing runs without a wheel change.
