Taylor Hobson (Great Britain)

Devices for measuring the geometry of large-sized parts


Talirond 440/450 - measuring systems developed by Taylor Hobson for precise, complex measurements of geometry parameters of heavy products. They are used in various industries (automobile, bearing, aircraft, etc.). Depending on the design feature of the part, the 440 (with rotating table) model or model 450 with a rotating sensor is applicable.

Characteristic features of systems

  • Large measuring volume (diameters up to 450 mm, height up to 1.5 m)
  • High load capacity (up to 1000 kg)
  • High spindle accuracy (0.1 μm)
  • Management by computer (automatic or semi-automatic)
  • Measurements on three axes (rotation, vertical and horizontal)
  • Color graphical format of results with high resolution
  • Vector movement of the measuring arm
  • Possibility to program measurement sequence
  • Ability to save results in computer memory
  • Simplified operator / device communication

Measuring the cylinder block, connecting rod and crankshaft on Talironde 450


The lateral sensor has 100mm interchangeable probes used to solve various tasks. It is mounted in a special swivel lever, which allows the sensor to be placed in any desired position with respect to the measured surface (for measuring internal and external surfaces, from below, from above and at an angle). In the Talirond 440 model, the change of the sensor position is motorized, and control is performed from the program.


One of the innovations of Talirond 440 is the auto-tracking mode, in which, in the case of the sensor leaving the measuring range, the radial lever moves it to the return to the range. The resultant count is added from the sensor reading plus the reading from the scale of the radial arm.

ULTRA software allows analysis:

  • Circularity (deviation from roundness)
  • Vertical straightness
  • Horizontal straightness
  • Perpendicularity
  • Planarities
  • Parallelism
  • Concentricity
  • Alignment
  • Cylindrical-Beating
  • Harmonics
  • Radius
  • as well as makes measurements of discontinuous surfaces, remove (not take into account) uncharacteristic irregularities, defects.
