  • Multicurve CityCrown Lathe
  • CNC Lentucular CityCrown Lathe

CityCrown has built and supplied more machine systems to manufacturers of Contact Lenses than any other company.

Although CityCrown ceased manufacturing new machines in 1999, the company supports several thousand machines worldwide and continues to service and rebuild machine systems to their original specifications.

CityCrown Limited is a wholly owned subsidiary of Sterling Ultra Precision Limited (Aylesbury, United Kingdom).

Sterling also acquired the assets and technology of ARM Electronics, which produced all the proprietary electronics and software used by CityCrown machine systems.

The combination of complete spares inventory, trained personnel and access to all source code and electronic design, has enabled the company to continue to produce “upgrades” for machine systems even when original parts manufacture has been disrupted by third party suppliers.
