Ball Wavimeter
Our Ball Wavimeter makes fast, accurate measurements of the waviness and roundness of balls used in ball bearings. It does this by using a specially designed spindle to rotate a ball at several hundred rpm while detecting the vibration speed with a contact sensor and displaying the waviness and roundness on the screen of a Synchro Wave Analyzer.
Features
- High-precision measurement: Practical measurement accuracy of 10 nm.
- Dedicated compact speed sensor with flat characteristics (10 times greater sensitivity than laser Doppler vibrometer) originally developed and manufactured by Sugawara.
- Speedy measurement: Real-time measurement (time required for race setting: 30 sec or less).
- It is possible to choose between two different drive units so measurements can be performed over a wide range of ball sizes including miniature ball bearings (0.3–60 mm)
- Dedicated Pusher for stable measurement.
- Replaceable Arbor for measurement of rings of different sizes.
- Measurements can be made in a total of 15 different units, including nmWcla, nmPC, nm, and nm/rad
- Measurement results can be displayed on the analyzer in various ways, such as numerical values in the L, M, and H bands, polar graphs, spectral plots, and vibration waveforms
- The equipment can record and play back up to 30 seconds of vibration noise, allowing quality control to be performed based on the raw vibration waveforms
- Recording data, measurement data, measurement conditions, and screen copies can be saved to a USB memory
- Hard copies of the screen display can be made using an optional USB thermal printer
Synchro Wave Analyzer SWA- series
This wave analyzer works with all Wavimeters. The measurement results are divided into numerical values by frequency band and displayed as spectral plots and in polar coordinates. In addition, since the waviness waveform is displayed in real time, it can also be viewed in the same way as an oscilloscope.
