CNC turning service
We translate the diameters, runout, concentricity, threads and surface requirements on your drawing into one production route. CNC turning, C/Y-axis turn-mill, sliding-head production, deep-hole drilling, grinding and honing stay under the same quality plan. A one-off replacement and a repeat series therefore follow the same approved revision and inspection record.

FAQ
CNC turning questions
What is the maximum CNC turning size?
CNC turning capacity extends to Ø700 mm diameter and 4000 mm length. This range covers long shafts, heavy flanges, rings and tubular components.
What tolerances and finishes do you hold?
Typical tolerance on turned features is ±0.02 mm. Cylindrical or internal grinding and honing produce tighter fits and surfaces down to Ra 0.4 µm.
Can you machine long shafts and deep bores?
Yes. We turn shafts up to 4 m with a steady rest and deep-hole drill axial bores to the same maximum length. Runout, straightness and bore-axis checks are recorded in the inspection plan.
Do you produce small turned parts at high volume?
Yes. Sliding-head automats run Ø10–20 mm bar for high-volume pins, connectors, spacers and similar small components. Series control uses a sampling plan and requested Cpk records.
