A Frame That Fits When It Reaches Your Assembly Line

A machine frame carries the guides, motors and gearboxes of your machine. If a mounting face is out of flat or a bore is out of position, assembly stops. We plan welding and machining together: datum faces and machining stock are agreed at the drawing review, the frame is welded in fixtures, and faces, bores and bolt patterns are machined after welding.

Critical dimensions are measured by CMM and reported. Frames leave us painted in your colour, with machined surfaces protected, and packed so they arrive the way they left. See our precision machined fabrications.

How we work

From Your Drawing to a Frame Ready to Assemble

  1. Datum plan

    Datums, machining stock and critical features agreed at the drawing review.

  2. Fixture welding

    Frames welded in fixtures with a weld sequence that limits distortion.

  3. Check and relieve

    Distortion measured; stress relief where the tolerance needs it.

  4. Machine

    Faces, bores and patterns machined in as few set-ups as possible.

  5. Measure and report

    Critical dimensions measured by CMM and reported.

  6. Paint and protect

    Painted in your colour, machined faces protected, crated.

FAQ

Questions from Machine Builders

Which tolerances can you hold on welded frames?

Tolerances follow your drawing. Faces and bores are machined after welding, so flatness and position are set by the machine, not by the weld.

Do you stress-relieve frames?

Yes, when the tolerance or the drawing requires it, before finish machining.

Do you supply measurement reports?

Yes. Critical dimensions are measured by CMM and reported with the parts.

Can you build in series?

Yes. Fixtures and programs are kept per part number for repeat orders.

Can we visit or audit?

Yes. Customer audits and first-article inspections are welcome.

Contract manufacturing for OEMs

Machine Frame Manufacturing in Türkiye

Machine builders in Germany, Benelux and Scandinavia outsource frames and housings when their own welding or machining is full, or when a part combines heavy fabrication and precision machining. We build to print, from one prototype to repeat series.

Welding and machining planned together

For very large beds see large-part machining.
