Detailed operation procedures for HB-3000B's hardness tester

HB-3000B hardness tester for the determination of non quenched steel, cast iron, nonferrous metals and soft texture of the bearing alloy, such as the value of the hardness of the.

1, the installation of pressure head and test bench

According to the type of metal and the estimated hardness of the choice of A. pressure cleaning anti rust oil, put it into the spindle and the rotation of the screw.

HB-3000B the B. test bench is installed on the lead screw. And then the samples were stable and close to the test bench.

C. rotation of the hand wheel, so that the test bench is slowly rising, the test sample and the pressure head contact until the hand wheel and nut produce relative sliding.

D. press the head of the press to the flat of the fixed bar.

2, select the test force

According to the type of metal and the estimated hardness of the required testing force.

3, the choice of test force to maintain the time

Open hb-3000b Brinell hardness tester switching power supply, power supply is switched on, according to the type of metal and the estimated hardness test load holding time, press the test force keep time button.

4, formal test

The test sample is placed on the HB-3000B test bench, and the test bench is rotated, so that the test bench is slowly rising, and the specimen is in contact with the pressing head until the hand wheel and the nut generate relative sliding. Press the start button, the hardness tester can automatically complete a cycle of work.

5, test and determine the results of the test

After the test, turn the hand wheel, take down the sample, with a reading microscope to measure the surface of the indentation diameter of the sample, the phase table to determine the hardness value of the sample. HB-3000B on the hardness of the switch machine can not be too frequent, off after 3--5 seconds to boot again.

6, after the test, cut off the power supply of HB-3000B's hardness tester, and take down the weight and the weight rack, and then cover the cover.
