Ceramic Zirco-Blocks Gauge Blocks

Opus ceramic gauge blocks


Opus ceramic gauge blocks (Zirco-Blocks) are manufactured from an exceptionally pure grade of  zirconia ceramic.

The commonly held belief that all ceramic materials are brittle and prone to catastrophic failure can now be dispelled with the remarkable zirconia ceramic    material which used to manufacture Opus Zirco-Blocks blocks.

 


 

Opus Zirco-Blocks are an effective substitute for the traditional steel gauge blocks and out perform them in many applications.The exceptional material combined with Opus’s specially developed lapping techniques and strict quality control produces a gauge of exceptional quality and value

Main features include:

  • Coefficient of thermal expansion close to steel
  • Good abrasion resistance - up to 10 times that of steel
  • Very high corrosion resistance
  • High thermal stability - does not react quickly to handling
  • Very good wringing properties
  • Highly resistant to knocks and drops
  • Does not burr easily

Opus Zirco-Blocks ceramic gauge blocks are rigorously checked for flatness of their measuring surfaces using a laser flatness interferometer. Each gauge is then calibrated in our own UKAS (United Kingdom Accreditation Service) accredited laboratory for length and graded according to the relevant national or international specification. You can view our UKAS accreditation schedule here.

Gauges can be supplied in sets or as individual sizes, special sizes up to 100mm (4 inches) in length can also be supplied upon request. To see our standard set compositions please click here.
