The electronic device Wilma is suited for straightness control of machine tool guides on which it is placed, related to a steel wire stretched at the ends by two adjustable supports with pulleys (optional). Any error is indicated by a LED display placed on the top of the instrument, and thanks to a digital micrometer table it’s possible to read the straightness deviation.

The instrument can store up to 254 measurements: using the appropriate serial cable all the measures can be uploaded to a PC and displayed by the software supplied. The instrument is powered by rechargeable batteries and is supplied in a ABS suitcase, complete with battery charger (220V-50 Hz), one coil spring steel, the “Wilma” Software CD-R and the user manual.

https://youtu.be/GOBaRl9UUfYWILMA Electronic device with laser for straightness testing with steel wire “Wilma” has been studied for straightness testing, for example of machine tools, on which it is placed, with respect to a wire fixed with two supports (not included) at the extremities. The eventual error is showed through a led display on the top of the instrument, while a digital micrometric table with reading to one thousandth gives the exact data. The device can stock up to 200 measures in a inner memory: then it is possible to transfer all the recorded data to the PC through the RS-232 interface. An electronic sheet will be automatically generated with a graphic of the straightness. Wilma is powered by rechargeable batteries and is supplied with battery charger (220 V – 50 Hz), one coil of harmonic steel wire, user’s guide and CD-R with “Wilma” Software.
