100 mm Flap Disc Burst Test with Unexpected Results

The test sample is a 100mm flap disc. Conduct visual inspection and eliminate samples with notches, cracks, edge chipping, moisture-induced deformation.

Inspect the test machine spindle, flanges and clamps. The flange size shall match the abrasive disc. Tightening torque shall comply with standards to avoid clamping slippage.

Reference burst-speed value for this sample: 22918 rpm, peripheral speed 80 m/s.

We increased the tester speed to over 23000 RPM, exceeding the critical burst specification.

After continuous high-speed operation, open the protective chamber.

As can be seen: this 100mm flap disc remains intact, with no cracking, edge chipping or bursting. Overall performance is stable..
