TABER ABRASION TESTER - STANDARD MATERIAL STRENGTH ASSESSMENT DEVICE

The Taber Abrasion Tester is a specialized device used to assess the abrasion level and strength of materials through a rotating friction mechanism. The product provides crucial reference data to help businesses optimize their material selection process.

OPERATING PRINCIPLE & MAIN FUNCTIONS 

• The upper part of the device is designed to include a sample clamp and a pair of abrasive wheels.

• During operation, the clamp containing the test sample is rotated by a motor, creating a driving force that causes the abrasive wheels to rub directly against the sample surface. • After a certain number of friction cycles as set, the device will automatically stop.

• The operator removes the sample and observes the wear level to assess the material's wear resistance.

INTERNATIONAL APPLICABLE STANDARDS 

The product perfectly meets the most stringent wear testing methods currently available, conforming to the following standards:

• DIN-53754, DIN-53799, DIN-53109, DIN-52347.

• TAPPI-T 476.

• GB/T1768-2006.

• ASTM D 4157, ASTM 4060.

DETAILED TECHNICAL SPECIFICATIONS 

• Rotation speed: 60 rpm and 72 rpm.

• Counting System: Counter with intuitive LCD display. Allows setting the number of runs with forward counting (from 0 to the set level) or reverse counting (from the set level to 0).

• Standard Sample Size: Outer diameter 100mm, inner diameter 6.35mm, thickness 3mm.

• Grinding Wheel Specifications: Outer diameter 52mm, distance between wheels 52.4mm.

• Wheel Load: Default load is 250g without added weights. Users can add 250g or 750g weights to increase the load to 500g or 1000g.

• Dust Suction Distance: Maintained at 3mm from the sample surface.

• Overall Dimensions: 480 x 320 x 310 mm.

• Machine Weight: 18kg (excluding dust suction unit). • Power supply: AC220V 50Hz 5A.

METHOD OF EVALUATING RESULTS (HOW TO READ ERRORS AND CALCULATE WEAR).

To determine whether your material is durable and scratch-resistant, after the machine has completed the set number of cycles, we have two ways to evaluate the results:

1. Visual evaluation (Observing the degree of damage) The simplest method is that after reaching the set number of friction cycles, the inspector will observe whether the sample is damaged or record the degree of damage on the material surface. This method allows for a quick assessment of the surface appearance of the product after the friction process.

2. Evaluation using precise data (Calculating Wear Index)

To obtain specific figures for comparing the quality of different materials, the principle is used: The more a material is worn, the more its mass decreases. The procedure is very simple:

• Step 1: Before testing, use an accurate electronic scale to weigh the initial weight of the sample.

• Step 2: Run the machine to abrade the sample surface at the specified rotation speed.

• Step 3: After testing, remove the sample and weigh it again.

• Step 4: Apply the formula to calculate the Wear Index: 

Wear Index =                                   

Explanation of the parameters in the formula:

• W1: Weight of the sample before being put into the testing machine (Example: 100 grams).

• W2: The weight of the sample after testing (e.g., the sample is worn down and lighter, weighing only 98 grams).

• W1-W2: This is the weight of the material that has been worn away into dust (in this example, 100 - 98 = 2 grams).

• N: The number of rotations the machine performed on the sample.

Simply put, the smaller the Wear Index, the less material is lost. This means your product has excellent durability and wear resistance. Conversely, the larger the index, the more easily the material is worn down.
