Brief definition

Titanium

Titanium and titanium alloys achieve the strength of steel at approximately 60 percent of the weight and are highly resistant to corrosion. Precisely the properties that make the material attractive for aerospace, medical technology, and the chemical industry also make machining difficult: low thermal conductivity, high toughness, and a strong tendency toward work hardening.

Challenge and solution

  • Challenge

    Heat accumulation in the cutting edge

    Low thermal conductivity means process heat is hardly dissipated via the chip – the cutting edge heats up significantly.

    Our Solution

    Pressurized internal cooling

    Coolant is delivered directly to the cutting edge; cutting speed is deliberately kept low.

  • Challenge

    Work hardening

    Insufficient tooth feeds harden the surface and cause premature wear on the subsequent cutting edge.

    Our Solution

    Defined feed per tooth

    We operate with a stable tooth feed rather than a cautious one – this protects both the tool and the surface.

  • Challenge

    Distortion of thin walls

    Clamping forces and residual stresses deform thin-walled structural components during unclamping.

    Our Solution

    Clamping concept + intermediate measurement

    The setup is determined in advance; critical dimensions are measured in the machine.

  • Challenge

    Tooling costs

    High wear makes tooling costs a relevant calculation factor.

    Our Solution

    Tool life monitoring

    Tools are replaced according to documented tool life – predictable rather than reactive.
Machining

How we machine this material

We machine titanium with low cutting speeds, high feed per tooth, and continuous internal cooling. Tools are replaced based on tool life, not on wear pattern – this keeps surfaces and dimensional accuracy stable.

  • High-pressure internal cooling
  • Tool life monitoring per tool
  • Clamping concept to prevent distortion of thin walls
  • In-process measurement

Frequently asked questions

FAQ Titanium

Which titanium alloys do you process?

The focus is on Ti-6Al-4V (Grade 5); Grade 2 in commercially pure titanium quality is also approved. Other alloys are reviewed on a case-by-case basis.

Why is titanium more expensive to machine?

Lower cutting speeds mean longer cycle times, plus higher tooling costs due to increased wear.

What tolerances are realistic?

With stable geometries, we achieve tolerances in the range of a few hundredths. For thin-walled components, we define tolerances together with you.

Do you provide material certificates?

Yes. Upon request, we provide material certificates as well as inspection reports with batch assignment.
