How much does the Voumard 1000 cost?
Estimated price range
Our best estimate for a cnc grinding machine in this class — not a quote from United Grinding (Voumard). Configuration moves it a long way.
Overview
The Voumard 1000 is an internal grinding machine for bores from 1 mm (0.04 in) to 100 mm (3.9 in), in workpieces up to 200 mm (7.9 in) in diameter and 200 mm (7.9 in) long. It is not in the maker's current lineup, and the listed figures have not been checked against a manufacturer page, so this page is written for someone weighing up a used machine.
The bore range is the reason to look at it. A 1 mm (0.04 in) bore takes a very small wheel, and a small wheel only cuts properly at very high rpm. The listed grinding spindle speed is up to 100,000 RPM, and the table adds that it is spindle dependent. On a used machine that qualifier decides a lot: ask which grinding spindles come with it and what speed each one reaches, because the spindles fitted determine which end of the bore range the machine can cover as delivered. The workhead is listed at up to 3,000 RPM.
For accuracy the table gives a positioning accuracy of < 0.001 mm and a bore roundness of < 0.001 mm. Treat both as values to prove with a test part on the machine in front of you. The control row names the C.O.R.E. platform, and machine weight is listed as ~3,500 kg (7,716 lb), the figure to hand to the rigger.

Strengths & Limitations
Strengths
- Bore range from 1 mm (0.04 in) to 100 mm (3.9 in) on one machine
- Listed grinding spindle speed of up to 100,000 RPM, depending on the spindle fitted, for very small wheels
- Listed positioning accuracy of < 0.001 mm and bore roundness of < 0.001 mm
- Machine weight of ~3,500 kg (7,716 lb) keeps transport and foundation demands moderate
Limitations
- Workpieces are limited to 200 mm (7.9 in) in diameter and 200 mm (7.9 in) in length
- The 100,000 RPM figure is spindle dependent, so a used machine may not reach it with the spindles it comes with
- Not in the maker's current lineup, and the listed figures could not be checked against a manufacturer page
- The table has no travel, power or wheel size rows, which leaves those to be confirmed on the machine

Frequently Asked Questions
01
The listed figures give a minimum bore diameter of 1 mm (0.04 in) and a maximum of 100 mm (3.9 in). Which part of that range a particular machine covers depends on its grinding spindles, since the listed speed of up to 100,000 RPM is marked as spindle dependent.
02
Up to 200 mm (7.9 in) in diameter and up to 200 mm (7.9 in) long. The table gives no workpiece weight, so ask for the workhead load limit before quoting heavy chucked parts. The workhead speed is listed at up to 3,000 RPM.
03
The table lists a positioning accuracy of < 0.001 mm and a bore roundness of < 0.001 mm. These figures could not be checked against a manufacturer page, and the model is not in the maker's current lineup, so have a test bore ground and measured before buying a used machine.
04
Three things follow from the listed figures. First, which grinding spindles are included, because the top speed of 100,000 RPM is spindle dependent. Second, whether the machine still holds the listed < 0.001 mm roundness on a test part. Third, handling: the weight is listed as ~3,500 kg (7,716 lb).
