Taber Abraser

The TABER Rotary Platform Abraser (Abrader) was developed to perform accelerated wear testing.First introduced in the 1930's, this precision built instrument rapidly became the world standard for evaluating abrasion resistance. Since its inception, the Taber Abraser has been used for quality & process control, research & development and material evaluation. Used to test a wide spectrum of materials, the abraser (abrader) has been referenced in numerous standards and specifications and is frequently called a Rotary Platform Dual (Double) Head Tester.

Description

Up to " thick specimens, are mounted to a rotating turntable and subjected to the wearing action of two abrasive wheels, which are applied at a specific pressure.

Characteristic rub-wear action is produced by contact of the test sample, turning on a vertical axis, against the sliding rotation of two abrading wheels. The wheels are driven by the sample in opposite directions about a horizontal axis displaced tangentially from the axis of the sample. One abrading wheel rubs the specimen outward toward the periphery and the other, inward toward the center. The resulting abrasion marks form a pattern of crossed arcs over an area approximately 30 square centimeters.

An important feature of the TABER Abraser (Abrader) is the wheels traverse a complete circle on the specimen surface. This reveals abrasion resistance at all angles relative to the weave or grain of the material.

Test parameters can be altered, which enables the user to determine the optimal setting for each product or material. The TABER Abraser (Abrader) allows you to select:

  • Load
    • standard range includes 250g, 500g and 1000g
    • optional counter weight increases range to 75g, 125g, 325g, 375g, 825g and 875g
  • Abradants
    • wide selection of Taber wheels available (resilient or vitrified)
    • specialty wheels
    • custom formulations
  • Vacuum level
    • programmable from keypad
    • adjustable vacuum nozzle clearance
    • range from 0% to 100%
  • Test Duration
    • programmable up to 99,999 cycles
  • Conditions
    • wet or dry

Each turntable has dual abrading arms that are precision balanced. Independently operated, the abrading arms can be raised (or lowered) to mount or inspect specimens. Each arm is loaded for 250 gram pressure against the specimen with the wheel mounting assembly in place (exclusive of the weight of the wheel). To increase the load to 500 or 1000 grams, a mount for auxiliary weights is located on the outside of the abrading wheel bearing assembly. The location ensures that weights are concentric with the abrading wheel. A stud on the rear end of the abrading arm is used to carry an optional counterweight (used to reduce the wheel load 125 or 175 grams). The stud is also used to hold an abrading wheel as a counterweight to compensate for the weight of the working wheel.

Taber Rotary Platform Abrasers (Abraders) are capable of providing reliable data in a matter of minutes, compared to the years that may be required by in-use testing

Models

The TABER Abraser (Abrader) is available in two models - with single or dual specimen tables. Both offer the same durable design and can be used interchangeably. Abrasers are available as 115V/60Hz or 230V/50Hz. When operated at 60Hz, the turntable rotates at 72 rpm. At 50Hz, the turntable rotates at 60 rpm.

TABER Abraser (Abrader) - Model 5130 / 5131
Models 5130 (shown in above picture) and 5131 feature a single specimen turntable.

  • Model 5130 - 115V, 50/60Hz [part# 985130-5]
  • Model 5131 - 230V, 50Hz [part# 985131-1]
  • CE approved

TABER Abraser (Abrader) - Model 5150 / 5151
Models 5150 and 5151 feature a dual specimen turntable, which allows you to perform two tests simultaneously (test two different or identical specimens for comparison or contrast). Separate function keys operate the turntables independent of each other.

  • Model 5150 - 115V, 50/60Hz [part# 985150-5]
  • Model 5151 - 230V, 50Hz [part# 985151-1]
  • CE approved

All TABER Abrasers (Abraders) are assembled in a sturdy, sealed aluminum housing and operated by a control panel membrane. Along with a numeric keypad, the control panel offers the following keys:

  • Cycle Selector Key - preset number of cycles
  • Vacuum Level Key - adjusts vacuum suction for test control
  • Cycles Completed Key - informs operator how many cycles have been completed (automatically activated once the start key is depressed)
  • Vacuum Only - enables user to operate just the vacuum (useful to clean the drive shaft and specimen table cavity or to operate the wheel refacer)

A vacuum system is included with each abraser (abrader), and is critical for the proper operation of the instrument. The vacuum suction pick-up nozzle(s) is hinged to an adjustable mounting at the rear of the housing. This allows the height to be modified for accommodating varying specimen thickness.

Precision stainless steel weights of 250 grams and 750 grams are furnished to provide standard wheel pressures of 500 and 1000 grams. NOTE: Weights are marked to show total load on each wheel. This marking includes the weight of the abrading arm.

Incorporated into the rear of the abraser (abrader) are three additional electrical receptacles. Conveniently marked, each receptacle has been designated for the vacuum system or optional accessory instruments, and enables the user to control the operation from the abraser (abrader).
