How We Work
From Idea to Part in 5 Steps
We manage every project through a disciplined, transparent process – from the first technical drawing to delivery.
Technical Drawing
We analyse your request and clarify the drawing and material plan together with you.
CAM Programming
The part's CNC toolpaths are optimised and programmed in CAM software.
CNC Machining
The part is machined to tight tolerances on our lathes and milling centres.
Quality Control
Every part is inspected with measuring equipment and a quality report is prepared.
Delivery
Approved parts are packed and delivered to you on time.

Frequently Asked Questions
Your Questions Answered
The most common questions about our CNC machining processes.
We offer CNC turning and milling across a wide range of materials, including steel, stainless steel, aluminium, brass, copper, bronze, cast iron and engineering plastics (POM, PA).
Depending on part geometry we machine to tolerances as tight as ±0.005 mm, inspect every part with measuring equipment and provide a quality report.
Yes. We accept orders of every size, from a single prototype to high-volume series production. With rapid prototyping we turn your design into metal in a short time.
Once you send us your technical drawing or sample part, our engineering team usually gets back to you with a price and lead-time quotation the same day.
Yes. Using reverse engineering we can measure your sample part, create a technical drawing and reproduce the part one-to-one.

Konya, Ankara, Izmir: Anatolia's Machinery Manufacturing Centres and CNC Capacity
Turkey's machining capacity is not limited to Istanbul and Bursa; Konya, Ankara and Izmir are Anatolia's machinery manufacturing centres, each with a different sectoral character. Konya for agricultural machinery, casting and automotive suppliers; Ankara for defence, aerospace and rail; Izmir for machinery manufacturing, stainless and port access. This article compares the three centres in a table, examines each one's strengths and weaknesses for European buyers, lists other Anatolian centres, offers a practical evaluation and visit plan, gives an example of three parts from three cities and answers FAQs.

Deep Hole Drilling and Thin-Walled Parts: Challenges, Methods and Design Recommendations
Holes longer than five times their diameter and parts with wall thickness below 1 mm are two classic challenges that multiply cost and risk in CNC machining. Drill drift, chip packing and heat in deep holes; clamping deformation, chatter and thermal expansion in thin walls. This article covers both from the supplier's and the designer's perspective: when a hole counts as deep, the problems, methods including gundrilling and BTA, deep holes on Swiss-type lathes, when a wall counts as thin, workholding solutions, design recommendations, cost impact and FAQs.

Swiss-Type Turning for Electronics and Connector Parts: Pins, Housings, Contacts
The electronics and electromechanical sector is the most natural market for Swiss-type turning: pins, sockets, contact housings, sensor enclosures and cable glands with Ø0.5–20 mm diameters, ±0.01 mm tolerances, plated surfaces and volumes in the hundreds of thousands. This article is a practical guide for electronics and connector manufacturers: typical part families, material selection, tolerance and surface, the plating chain, volume and delivery model, quality system and documents, points to watch when sourcing from Turkey, an M12 sensor connector example and FAQs.
