Key takeaways

  • Tight tolerances = perfect fit — no screw-locking, no part misalignment in your assemblies.
  • High-precision CNC machining holds critical features to ±0.01 mm.
  • Custom parts with stable lead times you can plan production around.
  • Metals and engineering plastics; prototype to low-volume production.

Why fit and tolerance matter

In automation equipment, a few hundredths of a millimetre decide whether parts assemble cleanly or bind. Loose tolerances cause misaligned holes, screws that won't seat, and mechanisms that jam. Precision CNC machining controls hole position, flatness and dimensions so mating parts fit first time — and stay reliable over the machine's life.

Precision machining for automation parts

  • Tight tolerances: ±0.01 mm on critical features; controlled hole position and true flatness for clean assembly.
  • Perfect fit: mating faces, bores and threads made to spec so fasteners seat and parts align.
  • Repeatability: consistent parts across a batch, so every unit fits the same.
  • Stable lead times: dependable scheduling for your build plan.

Frequently asked questions

How tight are your tolerances?
Standard is ISO 2768-m (±0.1 mm), with critical features held to ±0.01 mm using precision machining and verified by CMM inspection.
Why do my automation parts misalign or bind?
Usually loose tolerances on hole position, flatness or overall size. Precision machining controls these so mating parts align and fasteners seat correctly, first time and every time.
What are your lead times?
We offer stable, dependable lead times you can plan around; exact timing depends on part complexity, material and quantity, confirmed with your quote.
