ONO SOKKI – VC-3200 –

1. TEDS Function

It avoids setting errors, saves your time and effort of troublesome calibration and measurement preparation.
 

2. Logarithmic bar chart indicator

Easily viewable small level vibration
 

3. Headphone volume MUTE function

Mute function protects ears from impulsive sound when a sensor is attached.
 

4. Power averaging operation/judgment function

Power averaging operation and its judgment are possible.
 

5. ISO 2954:2012 compatible filter

Enables rotation and mechanical vibration measurement of rotating and reciprocating machines.

Quality judgment of products using vibration

– Pass/fail judgment of bearing using vibration
Rotate the bearing and detect the vibration value for judgment. By focusing on the frequency band, it is possible to know the content of detected defect (flaw, foreign material inclusion, imbalance etc.). Speed sensor is also used along with accelerometers. In that case, it is necessary to set the VC-3200 in external input mode.

Detection of abnormal operation of machine tools

– Detecting axial runout of a machine tool
Axial runout of machine tools has a great influence on the accuracy of finished product. Basically the runout of axis is measured by displacement gauge, which, however, is difficult due to environmental conditions, working conditions, cost, etc. Because the VC-3200 can detect abnormality of axis according to vibration level, it is not influenced by environmental conditions and can be used for usual monitoring. The greater the axial runout, the greater the vibration level. In other words, monitoring the amount of vibration continuously and checking it lead to finding abnormality of the machine tool.

Facility monitoring

– Monitoring vibration to detect abnormality of bearings, gears and other parts of production facilities without attendance
Facility diagnosis used to take a lot of work and time. An operator must measure and keep watching vibration from the facility because the vibration change gives an indication to know the timing of parts replacement or even abnormality. The VC-2200 / VC-3200 can continuously monitor vibration to detect unusual movement, prevent it from serious breakage and save the labor. The frequency band can be specified that might indicate the abnormality.

Detection of break and wear of tool

Detecting drill bit break, tool bit break etc of operating machine tool without attendance
For the machines which process quite a large quantities of parts, such as NC machine, unattended operation is employed. If the drill bit or other tool is broken during unattended operation, it causes defective products. Reprocessing or disposal of these defective products is nothing but waste of money. The VC-2200 detects vibration when the drill bit is broken and makes stop the operation if occurred, as a result, minimizes producing defectives. Worn drill bit also lowers processing accuracy. Monitoring vibration change and checking the operation help to improve the processing accuracy.
