Home · Services · CNC Turning Service · CNC turning · 01 Turn-milled parts in a single setup. Three turrets, twelve axes, sub-spindle. Complete machining of shafts, axles and hydraulic parts from Ø 10 – 250 mm. Send your drawing 06188 9953-0 At a glance Nakamura NTY³ · 12 axes · 3 turrets Diameter Ø 10 – 250 mm Bar work up to Ø 80 mm Chucked parts up to Ø 250 mm Length up to 1,200 mm between centres CNC turning is the backbone of our production. We have been turning precision parts for automotive, hydraulics and mechanical engineering since 1985. On the Nakamura NTY³ turn-mill centre three turrets work simultaneously — complex geometries are finished in one setup, repeatably, with no re-clamping errors. Capabilities What we turn.

Accepted Answer

From single parts and prototypes up to medium series. The three turrets of the Nakamura NTY³ make even complex parts productive — batch sizes from a handful to five figures are economical.

Question 2

What tolerances are realistic?

Accepted Answer

In turning we hold ± 5 μm on the diameter and Ra ≤ 0.4 μm on the surface. For tighter requirements we add CNC cylindrical grinding on the Studer S33 in-house — that brings micron tolerances and Ra ≤ 0.2 μm within reach.

Question 3

How long does it take to get a quote?

Accepted Answer

Once we have your drawing and quantity you will receive a quote without obligation within 48 hours.

Question 4

Do you machine hardened materials?

Accepted Answer

Yes — hard turning from HRC 45 to 62 with CBN inserts, followed by grinding where needed. Typical for hydraulic pistons and gearbox shafts.
