Overview

Machine builders buy a wide mix of parts: precision-machined shafts, housings and plates, welded frames and bases, sheet-metal guards and enclosures, gears and transmission parts. Volumes are usually low to medium, drawings change between machine revisions, and many parts are needed again years later as spares. That makes flexible CNC capacity, reliable welding and clear revision control more important than extreme volume.

Türkiye has a broad machinery supply base, from job shops with 5-axis machining centres to fabricators that weld, machine, paint and assemble complete frames. Many suppliers already build to European drawings and standards and ship regularly into the EU.

On Metraxio you describe the part and its requirements once; the platform structures them into process, material, tolerance and certification criteria and shows which facilities fit before you invite quotes.

Typical parts & components

  • Shafts, spindles, rollers and bushings
  • Machined plates, blocks and housings
  • Welded frames, bases and machine beds
  • Sheet-metal guards, covers and enclosures
  • Gears, sprockets and pulleys
  • Brackets, clamps and fixtures
  • Spare and wear parts for existing machines

The processes, materials and requirements below are an editorial reference of what is typical for machinery programs — not a statement about facilities in the Metraxio network.

Common manufacturing processes

Typical materials & grades

Certifications & compliance

What buyers in this industry commonly ask suppliers for. Exact requirements depend on the program, customer and part.

Supplier certifications

  • ISO 9001 Common

    Baseline quality system for machinery suppliers.

  • ISO 3834 Common

    Welding quality requirements for demanding welded structures.

  • EN 1090 Sometimes requested

    When parts are structural steel or aluminium components.

Standards & regulations

  • ISO 2768 Common

    General tolerances on machined parts.

  • EN 10204 Type 3.1 Common

    Material traceability for load-bearing parts.

  • CE Marking Sometimes requested

    Applies to the finished machine; suppliers support with documentation.

  • AWS D1.1 Sometimes requested

    Structural welding code used on some international projects.

Quality & documentation

  • Dimensional inspection reports on critical features.
  • Material certificates to EN 10204 3.1 where material traceability matters.
  • Welding to qualified procedures, with welding coordination per ISO 3834 for demanding welded structures.
  • Coating thickness reports for painted and powder-coated parts.
  • Clear drawing revision control, especially for recurring spare parts.

Typical tolerances & surfaces

  • Bearing seats and fits: typically ISO fits such as H7/g6, with ±0.01–0.02 mm on critical diameters.
  • General machined dimensions: often ISO 2768-m or -f.
  • Welded frames: fabrication tolerances per drawing, with functional faces machined after welding.
  • Surface roughness: commonly Ra 1.6–3.2 µm; ground surfaces Ra 0.4–0.8 µm.

Sourcing from Türkiye

Türkiye combines a deep contract-manufacturing base with short routes into Europe. Industrial goods move between Türkiye and the EU under the customs union, so buyers typically avoid EU import duties on qualifying parts.

  • Many European destinations can be reached by road within several days; actual transit depends on origin, destination, customs handling and cargo.
  • Common delivery terms are EXW, FCA and DAP; Metraxio keeps the agreed Incoterm attached to the quotation and order.
  • Welded and machined frames can ship as complete, painted sub-assemblies, reducing handling at your plant.

How Metraxio qualifies suppliers

Every request is checked against each facility's structured profile before any supplier is invited.

  • Hard criteria: the required process (e.g. 5-axis milling, welding), the specified material, part size limits and any required certifications such as ISO 3834.
  • Missing data is not a rejection. If a facility profile does not yet state something, the result is "Needs More Information" rather than "Not Qualified".
  • No match yet? You can continue with Managed Sourcing and the Metraxio team runs supplier discovery for you.
  • Facility identities stay anonymous during the technical assessment.

Example project

How a typical request moves through Metraxio

Welded machine base with machined mounting faces — 12 pcs per year.

  • The buyer uploads a welded assembly drawing in S355 with machined interfaces and a paint specification.
  • Metraxio structures the requirement: welding and fabrication, CNC machining after welding, carbon steel S355, painting, quantity per year.
  • Facilities are assessed on welding, machining envelope and finishing capability.
  • The buyer compares quotes from qualified facilities in a Supplier RFQ.

Frequently asked questions

Can I source single spare parts?

Yes. Single parts and small batches are common in machinery. Stating the quantity lets the assessment favour facilities that work at that scale.

Do parts suppliers need CE marking?

CE marking under EU machinery legislation is the responsibility of the machine manufacturer, not of the parts supplier. Suppliers typically support you with material certificates and inspection reports.

Can one supplier weld, machine and paint a frame?

Many fabricators offer welding, post-weld machining and coating in one place. List all steps in your requirement so facilities are assessed for the full scope.

How are drawing revisions handled?

Attach the current revision to the project. Quotations and orders reference the requirement, so it stays clear which revision was quoted and produced.
