Rockwell testing machine

It is defined as the resistance to indentation, and it is determined by measuring the permanent depth of the indentation. More simply put, when using a fixed force ( load) and a given indenter, the smaller the indentation, the harder the material. The Rockwell test determines the hardness by measuring the depth of penetration of an indenter under a large load compared to the penetration made by a preload. There are different scales, denoted by a single letter, that use different . Electronic scale conversion.

Adjustable timing function.

Includes standard accessories. Manually handles test force and preliminary test force selection. Motor drive controls loading sequence. HM-2Series with AVPAK Software. This system is available in Regular, Superficial or Twin Scale models and capable of testing in all of the regular and . Often found in testing laboratories and workshops, these testers are built to sit atop a work bench and test sample blocks.

Bench models come in two types: Analog models display the test result through a dial on the front of the machine. They are simple and easy to use and very accurate.

Digital models display the test result . In this test, hardness is measured by determining the depth of residual penetration by a steel ball or a diamond point under load. Hardness Testing Machine. Rockwell testing is the most commonly conducted hardness testing, ashe testing procedure is simple and the readings can be directly attained from the testing machine.
