Precision CNC machining & turning
First In Service machines heavy components, shafts and complex geometries to ±0.02 mm (±0.0008 in) in Tallinn, Estonia. The envelope reaches Ø 2,700 mm (106 in) in turning, 13,000 mm (512 in) in length and 4,500 mm (177 in) in height on FERMAT boring mills, vertical turning lathes and horizontal lathes, with dynamic balancing of rotating parts up to Ø 4,000 mm (157 in) and 4,000 kg (8,800 lb).
Precision machining for parts too large for most CNC shops.
Our machine park is built for heavy components, shafts and complex geometries. We turn and mill parts up to Ø 2,700 mm (106 in) and 13,000 mm (512 in) in length, holding tolerances down to ±0.02 mm (±0.0008 in).

What is the maximum part size for CNC machining?
Diameter up to Ø 2,700 mm (106 in), length up to 13,000 mm (512 in), height up to 4,500 mm (177 in).
Do you machine complex alloys?
Yes. We regularly machine stainless steel, duplex, super duplex, titanium, Inconel and Hastelloy.
What documentation is provided for machined parts?
Dimensional inspection reports and material certificates (EN 10204 3.1, 3.2 on request) accompany every delivery.
How a heavy component crosses the shop
Machining heavy components is a different discipline from machining small ones. A 3-metre shaft or a 40-tonne housing gets a setup plan before it gets a spindle: how it is supported so its own weight does not distort the datum, in what order features are cut so residual stresses release early rather than after the final pass, and where in the sequence dimensional checks catch drift while there is still material to correct it.
Our engineers review every drawing for manufacturability before quoting. Sometimes that means telling you a ±0.02 mm (±0.0008 in) tolerance on a particular feature will survive transport and temperature swing only if the mating part is match-machined, and sometimes it means telling you a looser tolerance would work and cost less. That conversation at the quote stage is worth more than any machining hour rate.
Duplex, super duplex, titanium, Inconel and Hastelloy are machined with tooling and parameters proven on previous work rather than improvised job by job. Every delivery ships with its dimensional inspection report and material certificates.
