First, clamping sample

Place the cut samples on the test bench according to the standard requirements.

Keep the sample flat, tighten the compression nut and gasket, and tighten the sample fixing ring with hexagon wrench.

Clamping grinding wheel and weight

Install the pre-ground standard grinding wheel on the inner front of the balance arm and tighten the nut.

Clamp the corresponding weight weight or counterweight according to the required pressure.

According to the specifications of the grinding wheels tested for different materials in the corresponding standards, the grinding wheels of the corresponding specifications shall be installed.

Second, the start

Turn on the power switch.

Set the preset winding number on the counter.

Press the start button and the motor drives the rotary plate to start rotating.

Note:

1. When the grinding wheel grinds to the sticker or the surface of the grinding wheel is abnormal, it shall be replaced.

2. Before each sample is tested, the grinding wheel shall be cleaned with a brush.

Sample result evaluation

After reaching the predetermined number of laps, the instrument will automatically stop or according to different standard requirements, determine to reach the end of the test is to press the red stop button to stop the test, turn off the vacuum cleaner. Samples were taken out for evaluation.

Evaluation method (for reference only, see the standard provisions for details) :

Mass loss method

Samples before and after the test (together with double-sided adhesive to hold the sample) were weighed using a balance accurate to 0.1mg to calculate the percentage of weight loss.

Force loss method

Strength test was carried out on samples before and after the test with a strength tester, and the percentage of strength loss was calculated.

Predetermined lap number appearance change

Appearance evaluation (usually wear through, light transmittance change, etc.) is performed after the predetermined laps
