There are many types of hardness meters, the most commonly used Luo, British, Vita, and microscopic hardness testing.The Lowl hardness measurement method is one of the most common hardness test methods.It is represented by the plastic deformation concentration of the material (including the preset load and the main load) of the material (including the pre -load and the main load), which is represented by the pressure head (including the diamond cone or quenching steel ball).
How to use the hardness meter
1. Prepare work before the test to adjust the speed of the main test force. The handle is placed in the unloading position, and the handle is transferred to the position of 1471N.The block raises the main axis, plus the test force, pull the handle and the main test force, and observe the big pointer from the beginning to the stop time.Repeat until the right.2. The choice of test force to rotate the handlebar to align the red spots for the selected test force. However, when the test force is changed, the handle must be placed in the rear limit position.3. When installing the heading head, you should pay attention to eliminating the gap between the head and the spindle end surface. The method of eliminating is: install the pressure head, and then use the screws to gently fix it.After the wheels plus the initial test force, pull the handle to add the main test force to the head, and then tighten the screw to eliminate the gap between the spindle and the head.
