Rockwell hardness tester in the use of the process encountered failure has how to solve

Rockwell hardness tester is suitable for metal Rockwell hardness test. This test method is characterized by measuring the indentation depth and reading the hardness value of the sample directly on the dial or digital display screen of the hardness tester, which is convenient, simple, rapid and high efficiency. Small indentation, small damage on the working surface of the parts, suitable for batch parts testing; Rockwell hardness test has a wide range. Because the hardness tester is affected by external and...

The operation of the tensile testing machine should not be sloppy at all

Tensile testing machine operating procedures: 1. Preparation of the specimen: The tensile testing machine takes the mark distance in the middle of the specimen or uses the foot mark gauge at...

Look at this! TABER wear testing machine maintenance procedures

TABER abrasion testing machine since its introduction. This precision instrument is widely used for accelerated wear testing, providing reliable material wear test data in minutes. Widely used in plastic, paint, laminate, leather, paper, ceramic, carpet, glass and other materials wear test. TABER wear testing machine is suitable for wear resistance test of leather, cloth, paint, paper, floor tile, plywood, glass, natural rubber, etc. The method is to cut the specimen with a standard cutter, wear it with a specified type...

Experience to share TABER wear testing machine calibration method Quick look

TABER abrasion testing machine is suitable for leather, cloth, paper, paint, plywood, leather, floor tile, glass, natural plastic and so on. The test method is that a pair of grinding wheels are mounted on the rotating sample, and the specified load is applied. When the sample rotates, the grinding wheel is driven, so as to wear the sample, and the weight loss is the weight difference before and after the test. The abrasion tester produced by Taber is the...

Ten minutes to read DIN wear testing machine test operation methods and principles

DIN wear testing machine is an important indicator of the wear performance of many rubber products. Widely used in rubber tires, chariot tracks, soles and other rubber products with wear resistance as the main performance of the physical property test, with high efficiency, good reproducibility and easy operation characteristics, is to assist the industry to control the quality of the product state of the weapon. Tensile: maximum force, tensile strength, elongation at break, modulus of elasticity, etc. Bending resistance: maximum strength,...

These small details of using TABER wear testing machines cannot be ignored

TABER wear testing machine is suitable for cloth, paper, paint, plywood, leather, floor tile, glass, natural plastic, etc. The test method is a pair of grinding wheel on the rotating test material, and the specified load, the test material rotates to drive the grinding wheel, for the wear test material, the wear loss weight is the weight difference before and after the test. Generally used to test leather products, the test specimen is rotated on a horizontal platform, two...

Look for these advantages before buying a load displacement curve

The load displacement curve is suitable for the elastic displacement test of large-size switch keys, and can be applied to the pipeline signal trigger test to send out good and bad product signals to achieve the purpose of quick detection of OK and NG products. The measurement curves are memorized by the computer and can be enlarged or reduced at any time. N curves can be placed arbitrarily on an A4 paper. The computer directly prints and stores load-travel...
