QUINDOS Cylindrical WormMTW-510-WHX-001


Measurement of Cylindrical Worms on a Coordinate or a Gear Measuring Machine.


Cylindrical worms of the type ZA, ZI, ZN, ZK and ZC (see DIN 3965) can be inspected on a precision Coordinate Measuring Machine or a Gear Measuring Machine with the option QUINDOS Cylindrical Worm.
The worms might have single or multiple starts, with left or right hand leads.

The measurement of worms on a Leitz Coordinate Measuring Machine equipped with QUINDOS software can be done in vertical as well as in horizontal position, without a rotary table.
A significant advantage when measuring long worms, compared to a dedicated Gear Measuring Machine using a rotary table.


Leitz Worm Gear Measuring Technology: fast, precise and cost-efficient!

The following features of a cylindrical worm can be evaluated:

  • The lead at any diameter
  • The axial profile at any position
  • The axial pitch
  • The runout for a given sphere diameter
  • The tooth thickness at the reference diameter or at a given distance from the outside diameter.
  • Dimension over balls (pins)
  • Topography (flank form)

Measurement of a Cylindrical Worm with a Leitz Coordinate Measuring Machine and QUINDOS is as easy as with a dedicated Gear Measuring Machine: after entering the worm parameters, QUINDOS generates automatically the moving path and all required probing points and scan lines, including start and stop points and probe changes for the Coordinate Measuring Machine (CMM).

Due to the usually tight tolerances of Worms, only high precision Measuring Machines with a small probing error P and scanning capability (i.e. Leitz PMM-C) should be used for such measurements.
