  • Verification of the number of items in the delivery
  • Cleaning
  • Demagnetisation
  • Visual inspection for damages

Profiled master ring

  • Determination of the gearing data by means of standards and existing drawings or
  • Creation of an inspection equipment drawing (on request at extra cost)
  • Removal of smaller damages on the gearing, wherever possible
  • Size inspection of the gearing by hand with the Abbe length measuring device or the Abbe-type length comparator
  • Form inspection such as profile, tooth curve, pitch and radial runout on gear measuring centres

Master gear

  • Issuing of an inspection certificate
  • Electronic archiving of the measurement results at FRENCO
  • Re-marking (on request at extra cost)
  • Wrapping in antirust foil

Delivery is approx. 2 weeks from receipt of the inspection equipment or measurement items (in Altdorf). Delivery can be expedited if agreed with Frenco (at extra costs). Delivery for calibrations is 6 weeks from receipt (in Altdorf).

Documentation:

An inspection certificate is issued for each inspected instrument. It includes:

Concentricity ring gauge

Taper mounting
mandrel

  • Inspection equipment data, nominal sizes, actual sizes and the overall evaluation on the cover page
  • Depending on the delivery volume and type of instrument, the graph of the gear measuring centre including profile, tooth curve, pitch and radial runout on the inside pages and
  • the explanation of the used abbreviations, traceability and measurement uncertainties on the back page.
