Chemical etching process Complex, burr and stress-free components with pinpoint precision

Chemical etching, sometimes referred to as photo etching or photochemical machining, is a metal machining process which uses chemical enchants to create complex and highly accurate precision components.

Precision Micro has advanced the principles of the chemical etching process, investing in new technologies and developing proprietary methods which have set the standard for accuracy and repeatability.

Chemical etching benefits

At Precision Micro we use digital tooling, which can be adapted and changed extremely quickly and cost-effectively. This ensures risk-free design optimisation without financial penalty.

Etched components are burr and stress-free with no mechanical force or heat used, leaving material properties unaltered.

As component features are machined simultaneously almost limitless part complexity is achievable, with accuracy to ±0.025mm.

Full range of chemical etching benefits:

  • Unlimited complexity – only pay for the first hole
  • No expensive hard tooling
  • Low-cost design iterations – fast
  • Burr and stress-free – metal properties unaffected
  • Lead-times in days, not months
  • Almost any metal
  • Accuracy to ±0.025mm
