Crankshaft balancing system

Contactless, rotationless

The very high precision and full (100%) raw crankshaft digitization operation localizes very quickly all eccentric weights and calculates instantly the ideal "tooling axis", leading to a final "balanced" crankshaft result. It helps :

  • to drastically optimize and reduce the tooling costs
  • to instantly compare the raw crankshaft to its CAD/CAM model
  • to discard, prior to initial tooling step, faulty crankshafts

    More than 82 millions crankshafts are produced every year (2012 data)

    • Automotive, thermic engine production
    • Rotating parts production
    • Balancing systems manufacturers
    Digitization time: 12 seconds
    Total cycle time: 25 seconds (Production line compatible)
    Balancing precision: 5g.centimeter
    • Raw crankshaft full digitization (100%)
    • No targets nor markers necessary
    • Option: "fine Tuning" balancing by portion

Volume calculation

Precise & fast measurement of complex volumes

From rock quarries, recycling industries to transport and logistic markets, the precise and fast measure of complex volumes, using 3D optical tools, improve production quality and optimize costs.
The volumetric weight is a mandatory data to precisely calculate the transport costs of logistic centers and their customers.
The addition of a 3D scanner and volume calculation system to a weighing unit optimizes freight and transport costs calculation.

  • logistics
  • Air, terrestrial, navy freights
  • Internet resellers
  • Weighing scale manufacturers
Volumetric precision: 2/1000th of the volume (example : 600L wastebag)
Cycle time: 1/2 second

3D Macroscope

High resolution 3D scanning
Wide field - Direct 3D measures


The system digitizes several views (3 000 to 10 000 dots/mm2) of an object and automatically fusion successive 3D point clouds. The volume is displayed in true colours, and can be manipulated an measured in 3D using the 3D GUI.

Adaptative meshing of the volume improves measurements accuracy and allows the 3D volume file transfer into standard CAD/CAM systems.

Automatic deburring

Robotized deburring

This operation, quite usual on production lines, removes burrs of each produced part, by tooling (or cutting) excess matters, often an unwanted result from industrial parts production processes.

Some deburring operations can be complex and delicate to achieve, and part surface condition can be altered by this process.

It can be interesting to quantify excess matter importance in advance, to avoid early tool wearness or breakage.
It can be optimized both production time and tooling costs by scanning in 3D each part and compare its shape to CAD/CAM model.

In this aim, an industrial study has been held in 2007 :

The following video shows 3D digitization (by means of a single 3D head) of a part. The real 3D shape is then compared to the CAD/CAM model. Deburring is then operated by a robot : Its trajectory takes care of a possible large excess of matter, which can be removed without any tool breakage risk.

An industrial version of this system would digitize the part in a few seconds, then proceed to the selective deburring of the excess matters. Moreover, any wrong shape would be discarded before entering the tooling unit.

Glass frame tracer

A new reading

The VIDEOMETRIC patent «3D geometry measurement of hollow ring, using axial stereovision with two opposite cameras" has been published recently.

Patent : "Hollow ring measurement" (in French)

This patent protects a fast and precise 3D measurement method for "hollow ring" objects, and by extension any "hollow shape".

A usage example can be the 3D digitization of the glass frame inner contour, a mandatory measurement for optical glass grinding, to fit the lens into the frame.

The optical principle consists in placing two cameras in opposition, on both sides of the ring.

Images are then handled thru VIDEOMETRIC 3D calculation to extract quickly,and with high precision, the inner contour 3D data.

System variant is using one real camera and one virtual camera, created with a mirror (flat, concave or convex) positioned opposite.

System benefits :

  • Reliability (No moving parts)
  • Compacity
  • Measurement speed
  • High 3D precision
