CNC turning in Bayrampasa, Istanbul
If you are looking for a CNC turning manufacturer in Istanbul: Aster Otomotiv has made its own parts in its Bayrampasa factory for about 20 years, and on the same lathes it also runs contract work from customers' drawings or samples. You send the drawing or sample; we turn the part, finish it on a machining center if needed, and deliver. On repeat orders we continue with the same machine and setup.
Our turning fleet
| Machine | Qty | Bar / chuck | Max. part, Ø × length | Speed (rpm) |
|---|---|---|---|---|
| Ray Feng RC32Gang-type CNC lathe | 3 | Bar-fed, ø32 mm | ø32 × ~100 mm | 6.000 |
| Hyundai KIT450Gang-type CNC lathe | 1 | Bar ø44 mm | ø165 × 190 mm | – |
| Goodway GLS-200Horizontal CNC turning center | 1 | 8" chuck, ø65 mm bar passage | ø185 × 480 mm (std.) | 4.200 |
Our Ray Feng machines are gang-type: tools sit side by side, so tool change time is short and cycle times drop on small parts. With three identical machines a high-volume job runs in parallel, and one machine down does not stop delivery.
Parts that suit turning
- Shafts, pins, bushings, nozzles and fasteners
- Valve and fitting bodies, couplings, plugs
- Flanged and stepped round parts
- Parts machined from large-diameter bar cut on our band saw
We cut large-diameter stock to length on an automatic band saw and machine it on our lathes. The lathes have no driven tooling, so parts needing cross holes or milled flats are finished on our machining centers. Turning and milling stay with one supplier.
Materials
Brass, alloy steels, stainless steel alloys, aluminum alloys and engineering plastics.
Quantities and way of working
On turning we typically work on repeat orders of 1,500 pieces and above. For lower quantities, send the drawing and we will assess it together. We take sample approval before moving to series production.
In-process measurement uses calipers and micrometers. If you need a measurement report or special inspection, tell us at quotation stage.
