taber wear test machine, wear test machine

taber wear-resistant testing machine, wear-resistant testing machineThe principle of the instrument:

The wear resistance of leather and plastic materials is mainly tested through rotary grinding, using various types of friction wheels to rotate on the sample. Select the default applicable weight set for testing material properties. Detect weight loss on the outer surface of the sample, such as obvious mechanical damage.

Specifications:

Test piece: outer diameter 108 mm, inner diameter 8 mm, 3 mm (D)

Grinding wheel: diameter 2”(M*45mm)1/2”(W)

Center distance grinding wheel: 63.5mm

Center distance grinding wheel and test wheel : 37~38mm

Rotation speed: 60/72rpm

Weight: 250g, 500g, 1000g

Counter: LCD, 0~999,999

Volume: 530 ×320×310+vacuum cleaner

Weight: 18 kg (excluding vacuum cleaner)

Power supply: 1φ, 220v/50HZ

Wear index calculation Formula: Wear Loss Weight/Formula Number of revolutions×100 *Wear process:

Lay the material to be tested on the turntable and two grinding stones press on it the material with a certain weight to make it wear.

When a sample with an area of ​​10 x 10 cm is subjected to abrasion, the surface material of the sample is abraded by full angle particles or silk fabrics to form a complete ring.

The grinding wheel rotates with the rotating surface of the sample disc, resulting in relative movement and wear, and the offset of the grinding wheel axis from the rotating axis of the turntable during the rotation process produces a sliding motion, causing the material is abrasive.

Simulate actual conditions of use or meet the test conditions specified in the standard:

- You can use a variety of different abrasive media and fittings are tested differently

-Can repeat the test on the same point of a material, up to 0.5\" of the material is broken or abraded

- Configurable Two speeds (60, 72 rpm), 0-50000 revolutions (100, 500, 1000 or 2500 revolutions can be set quickly) and 3 loads.

Vacuum cleaner to remove dirt:

The suction arm of the vacuum pump is connected by a hinge to the adjustable device on the back of the instrument, and the height can be precisely adjusted. adapted to different sample thicknesses

Ensure the stability and accuracy of the test:

Strict control ensures reliable results

Selected The selection of grinding wheel abrasives is subject to strict quality control, with high quality and good stabilityit
