What we do
We machine parts that OEMs design: switchgear housings, bogie connection parts, gearbox shafts, turbine transfer plates. Most of them go to assembly lines in Germany, the USA, France, Switzerland and Sweden.
Our job comes down to three things: hold the tolerance, prove it by measurement and deliver on the agreed date.

Frequently asked questions
Can Yağmaksan machine my part?
Most likely, if it fits these envelopes: milling to 1,600 × 800 × 700 mm, 5-axis to 800 × 800 × 550 mm, turning to Ø670 × 1,512 mm, Swiss-type bar work to Ø42 mm and gears to Ø260 mm and module 6. The machine park lists every machine. Send the drawing and we will name the machine it runs on.
Do you make prototypes or only series?
Both. We run single prototypes, first articles and series on the same machines, with the same inspection.
Which processes are outsourced?
Heat treatment, surface coating and painting, forging and casting. They run at approved suppliers under our quality system and are inspected in our laboratory on return. Everything else is done in our own facilities.
Which file formats do you accept?
STEP, IGES, DXF and PDF, up to 50 MB per request through the quote form.
