FAQ's

What is the difference between the Linear Abraser and Taber Rotary Abraser?

The Linear Abraser incorporates a "free-floating head" that strokes in a linear motion, and can test virtually any size or shape specimen. Adjustable settings enable the user to select stroke length, speed, and load. Plus, interchangeable attachments can be used to convert the instrument from a Wear Tester to a Scratch Tester; Crock Meter; or custom configuration. When used as a wear tester, a ¼" or 1/2" wide wear linear wear path is generated from 0.5" to 4" in length.

The Taber Rotary Abraser can test up to ½" flat specimens, 4" x 4" or 4" diameter. Two abrasive wheels contact the surface and as the table rotates, a circular wear path is generated. Because the wheels traverse a complete circle on the specimen surface, abrasion resistance is revealed at all angles relative to the weave or grain of the material.

What can be tested with this instrument?

Virtually any size or shaped material can be tested with the Linear Abraser. If you are not sure if this instrument will work for your application, submit specimens through the "Taber Test Your Samples" program.

How does this instrument test contoured surfaces?

Attachments (i.e. wear collet or scratch) are mounted on the end of a spline shaft. A precision bearing on the shaft creates a "free-floating head". This bearing is mounted on the end of the stroke arm, and permits vertical movement of the spline shaft. As the arm strokes in a linear motion, the spline shaft travels up and down to follow the contours of the surface.

How are the test parameters changed?

The Linear Abraser has eleven (11) operating stroke lengths that are adjusted manually. By changing the location of the crank pin, a connecting rod can be set to standard lengths between 0.2" and 4.0". A reference label under the cover indicates proper set-up for changing stroke lengths.

What types of abradants are available?

The standard abradants used with the Linear Abraser are referred to as a Wearaser™. Manufactured from the same materials as the world famous Taber wheels, both Calibrase^® and Calibrade^® Wearasers™ are available. Custom abradants are also available by contacting Taber Industries.

Over time, the inside of the collet may wear with use. Before replacing, we recommend cleaning the outside of the Wearser with a cloth and Isopropyl alcohol. If this does not resolve the issue, contact Taber Industries to purchase a new collet.

What are the differences between RUN and REFACE modes?

For testing convenience, a separate REFACE mode is included to allow the user to reface the Wearaser™. This eliminates the need to reprogram the number or cycles, and avoids adding additional strokes to the counter during a test. During normal testing, the Linear Abraser should be set to RUN mode. Both modes are user adjustable from 0 to 999,999 cycle counts.

What is the minimum load that I can test with? What is the maximum load?

Without any supplemental weights, the base load of the Linear Abraser is 350g. This consists of the weight support, spline shaft and attachment (wear collet, scratch attachment or universal head). The base load of the crock test is 418g. By removing the weight support, you can reduce the load by approximately 73g.

Using five (5) supplemental 250g weight discs, the maximum load of the Linear Abraser is 1600g (or 1668g if you the instrument is set-up to perform crock tests).

With optional accessories, the minimum load is 60g and the maximum load is 2600g.

What is the power requirement?

The instrument can be connected to 115 or 230 volt, 50/60 circuits. Two power cords are provided along with the appropriate fuses.

Can I correlate the results with a Taber Rotary Abraser?

Due to differences in how the wear paths are generated, testing parameters and the unique wear properties of each material, there is no standard formula to correlate test results between the Linear Abraser and Taber Rotary Abraser. If you are attempting to correlate the results, Taber recommends correlating through experimentation to determine the appropriate settings.
