The requirement for this tester was to quickly determine the effects of heat treatment on steel bearing races.Working Procedure – Rockwell Hardness Testing Machine Working Procedure – Rockwell Hardness Testing Machine 1) Check - Level of Machine should be proper. 2) Check - Machine should be in unload condition. 3) Check - Indenter Placement. 4) Check - Dial’s hands should be stationary. 5) Select - Proper Indenter according to Table A.
5.2.1 There are two general classifications of the Rockwell test: the Rockwell hardness test and the Rockwell superficial hardness test. 5.2.2 In the Rockwell hardness test the preliminary test force is 10 kgf (98 N). Total test forces are 60 kgf (589 N), 100 kgf (981 N) and 150 kgf (1471 N). In the Rockwell superficial
Depending on the model, the hardness tester covers load ranges from 0.3-250 kg or 3-3,000 kg. The macro hardness tester covers optical methods and differential-depth methods for your hardness testing applications. This includes Vickers, Brinell, Knoop or Rockwell.The 574 Series Wilson Rockwell Hardness Testers offer quality, durability, and an industry leading Gauge Repeatability and Reproducibility (GR&R) making this hardness testing machine best in class. This system is available in Regular or Twin Scale models and capable of testing in all of the regular and superficial Rockwell hardness scales and .profiles. The Rockwell test is the most popular indentation hardness test and is used in a wide variety of applications. Advantages of the Rockwell Test There are several reasons for the popularity of the Rockwell test. The test itself is very rapid. On a manually operated unit, a Rockwell test takes only five to ten seconds,
