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 Corvus is listed here as a five-axis tool grinder for small tools: a tool diameter range of 0.5 to 25 mm and a maximum grinding length of 200 mm, on a granite composite base with a footprint of 1,800 x 1,600 mm. Schneeberger's current lineup has no model under this plain name, so the listed figures should be confirmed against the documentation of the machine in question.
The grinding side is defined by a three-spindle head with automatic indexing. Each spindle can keep its own wheel pack mounted, so the head indexes from one operation to the next instead of an operator changing arbors. Spindle speed is up to 10,000 RPM and spindle power 5.5 kW. That power is in proportion to a 25 mm upper diameter: adequate for fluting small carbide tools, with little in reserve for anything heavier.
Coolant pressure is listed at up to 60 bar. Near the 0.5 mm end of the range the wheel contact is tiny and the flutes are narrow, and pressure is what keeps the wheel clean and the tool cool there. Positioning accuracy is given as ±0.001 mm and repeatability as ±0.0005 mm. Control is listed as Fanuc with Schneeberger MARS software. Axis travels, machine weight and any loading system are missing from the listed figures.

Strengths & Limitations
Strengths
- Three-spindle grinding head with automatic indexing, so several wheel packs stay mounted
- Tool diameter range starts at 0.5 mm and runs to 25 mm
- Coolant pressure listed at up to 60 bar
- Listed positioning accuracy of ±0.001 mm and repeatability of ±0.0005 mm
- Granite composite base on a 1,800 x 1,600 mm footprint
Limitations
- Tool diameter stops at 25 mm and grinding length at 200 mm
- Grinding spindle power is 5.5 kW, which limits stock removal on the larger tools in the range
- The listed figures contain no axis travels, no machine weight and no loader

Frequently Asked Questions
01
The listed tool diameter range is 0.5 to 25 mm and the maximum grinding length is 200 mm. Those two figures place it at the small end of tool grinding, where the low limit of 0.5 mm matters as much as the upper one.
02
As a 3-spindle head with automatic indexing. The spindle speed is listed at up to 10,000 RPM and the spindle power at 5.5 kW. With three spindles, separate wheel packs can stay mounted and be indexed into position as the cycle calls for them.
03
The listed machine footprint is 1,800 x 1,600 mm, on a granite composite base. No machine weight is given in the listed figures, so floor loading has to be taken from the machine's own documentation or nameplate.
04
Coolant pressure is listed at up to 60 bar. Positioning accuracy is given as ±0.001 mm and repeatability as ±0.0005 mm. The listed figures do not say how or over what travel the accuracy was measured, so ask for an inspection report with a machine.
