YOU-check Cross

The test specimen consists two cross-shaped lines in which ceramic measuring inserts are inserted at periodic intervals. These are arranged in such a way that the measurement is performed in the neutral fiber. This in turn ensures the highest accuracy.

Application
YOU-check is placed on the machine table and aligned. This is followed by the probing and measuring of the measuring inserts using the machine touch probe. The deviation of the center points from the desired deviations determine the accuracy of the machine. Compared to known ball plates, YOU-check has the advantage that the touch is performed from the inside. This makes the measurement extremely fast.

Clever functionality
With YOU-check, the advantages of aluminum (lightweight, minimal deflection and even temperature distribution) can be used as an ideal basis, while at the same time it can be used with any expansion factor.

In the test standard, a rod with almost zero expansion is used. This rod does not (almost) expand with increasing temperature. On the other hand, the test standard is evenly extended. The difference, ie, the difference in length, is used to recalculate the instantaneous length to the desired expansion factor (e.g., steel). The conversion is carried out automatically in the included software YOU-check, without the temperature being measured.

Option Plus
The optional Plus version provides additional, internal measuring surfaces for measuring the straightness and squareness with a sensor lever probe. The measuring surfaces are manufactured in the highest precision and are protected by their position extremely effectively against damage. The arrangement allows additional measurements in the center of the axle travel ranges. With this clever variation all deviations such position deviation, straightness and squareness can be measured.

Advantages:

  • Easy to use
  • Fast
  • Sophisticated system
  • Ultra-light
  • High precision
  • Optional straightness and squareness measurements
  • Lowest deflection

 

The length-standard YOU-check is extremely robust and can be handled and transported without any problem and without special precautions.

There are various possibilities for mounting on the machine. All together is a 3-point support with kinematic support. Further possible: fixation with magnets embedded in the feet or mounted on pallet.

Delivery including Calibration, calibration certificate SCS (ISO/IEC 17025) and software program YOU-check.
