Taber Abrasion Tester

Model: UT4073TA. ASTM D4060, ASTM D1044, ASTM D3884, ISO 5470-1, ISO 9352

Taber Abrasion Tester (also known as the Taber Wear Tester or Rotary Platform Abrasion Tester) is a globally recognized standard device for accelerated testing of material wear resistance. By simulating actual working conditions through rotational friction, it quickly evaluates the material's surface wear resistance, scratch resistance, and durability. It is widely used in the fields of material science and industrial quality control, mainly to quantitatively assess the wear resistance of materials.


Its core function is to measure the amount of mass (weight) lost or the depth of wear generated by a material after a certain number of rotations under specific friction conditions (such as particular friction wheels, loads, and speeds), thereby calculating the material's wear resistance indicators (such as amount of wear and wear resistance index).

General Introduction

Taber Abrasion Tester (also known as the Taber Wear Tester or Rotary Platform Abrasion Tester) is a globally recognized standard device for accelerated testing of material wear resistance. By simulating actual working conditions through rotational friction, it quickly evaluates the material's surface wear resistance, scratch resistance, and durability. It is widely used in the fields of material science and industrial quality control, mainly to quantitatively assess the wear resistance of materials.


Core Functions: 

Its core function is to measure the amount of mass (weight) lost or the depth of wear generated by a material after a certain number of rotations under specific friction conditions (such as particular friction wheels, loads, and speeds), thereby calculating the material's wear resistance indicators (such as amount of wear and wear resistance index).

Quantitative Abrasion Resistance Test: Measure the material's mass loss, thickness loss, gloss/transparency changes, and wear mark morphology under standard abrasive wheel, load, and speed, and calculate the Taber Abrasion Index. 

Accelerated Aging Simulation: Complete wear equivalent testing of several years of actual use within minutes, significantly shortening R&D and quality control cycles. 


Test Methods: 

Square or circular flat samples with a size of 100 millimeters are mounted on a rotatable platform, with a fixed platform rotation speed. The thickness of the sample material is 6.34 millimeters (materials greater than 6.35 millimeters but less than 40 mm are tested using optional attachments). Two TABER abrading wheels are pressed onto the sample surface under a specific pressure.

Taber Abrasion Tester

When the turntable rotates, the sample drives the wear wheel to rotate in the opposite direction from the sample's axial tangent direction. One wear wheel rotates outward, and the other rotates inward. At the same time, a vacuum removes the particles generated by friction. The wear wheels grind a complete circular ring on the sample surface, demonstrating the material's wear resistance from all angles. The friction-generated circular pattern has an area of about 30 square centimeters.


Each turntable has two precisely balanced wear arms. They can be independently raised or lowered to install or inspect the sample. Each arm, precisely balanced, applies a force of 250 grams, not including the weight of the wear wheel. With additional weights, the force can be increased to 500 or 1000 grams, and balance weights can be installed to reduce the force (using 50, 125, 150, or 175 gram weights).

Standard

ASTM F2068 Fatigue test system of Femoral Prostheses Implants, Hip Implants Testing

ASTM F2068: Standard Specification for Femoral Prostheses – Metallic Implants


ASTM F2068 covers metallic stemmed femoral prostheses used to replace the natural hip joint by means of hemi-arthroplasty or total hip surgical procedures. Prostheses for hemi-arthroplasty are intended to articulate with the natural acetabulum of the patient. Prostheses for total hip replacement are intended to articulate with prosthetic acetabular cups. Prostheses may have integral femoral heads or cones designed to accept modular heads. 

The mechanical strength (fatigue test ISO 7206-4, ISO 7206-6, shear strength test ASTM F1044, tensile test ASTM F1147, abrasion resistance test ASTM F1978), corrosion resistance, and biocompatibility of the head portions of one-piece integral implants are covered by this specification.

Instructions and Operating Steps

1. Preparation before the test

(1) Sample preparation

• Shape: round (φ100–110 mm) or square (100×100 mm), flat plane.

• Thickness: standard ≤ 6.35 mm; ≤ up to 40 mm (special fixture required) Taber Industries.

• Quantity: 3 parallel samples ≥ each group, taking the average.

• Pretreatment: Cleaned according to standard, constant temperature and humidity adjustment (e.g. 23°C/50% RH, 24h).

(2) Equipment and consumables preparation

• Choose a matching grinding wheel (e.g., CS-10 universal rubber wheel, H-18 hard grinding wheel, S-42 wire wheel).

• Calibrate the grinding wheel: The new grinding wheel needs to be pre-ground (50–100 revolutions) to remove surface burrs and stabilize before use.

• Setting parameters: speed (60/72 rpm), test speed (e.g. 1000/5000 rpm), load weight (250g/500g/1000g).

• Check the vacuum system: Ensure proper suction power to remove abrasive debris.


2. Test the operation steps

2.1. Install the specimen: Fix the specimen flat on the rotating platform to ensure no loosening or warping. 

2.2. Installing the grinding wheel and loading: Install the pre-grinding grinding wheel on the left and right arms, lower the arm body, and load the specified weight. 

2.3. Start test: turn on the vacuum→ start the rotating platform→ start counting→ reach the set number of revolutions and stop the machine automatically. 

2.4. Stop and clean: Raise the grinding wheel arm→ close the vacuum→ remove the specimen→ clean the grinding wheel and platform grinding chips. 

2.5. Repeat test: Replace the specimen or grinding wheel with a new specimen to complete the parallel sample test. 


3. Data processing

• Mass loss method: weighed with an analytical balance (accuracy 0.1mg) before and after the test, calculated:

o Wear rate = (initial mass - final mass) / number of revolutions tested (in mg/1000 revolutions).

o Taber wear index = 1000 / wear rate (the higher the value, the more wear resistance).


• Cosmetic evaluation: Visually/microscopically observed for abrasion, fluffing, peeling, discoloration, graded according to standards. 

• Optical / Thickness Measurement: Transmittance / Haze measurement of transparent materials; Measure the depth of wear marks on hard materials.
