  • Page 12: Preparation & Testing

    COPPER 45～315 2.5 Leeb Hardness Testing Principle The basic principle is: use an impact body of certain weight impacts against the testing surface under certain test force, then measure the impacting velocity and the rebounding velocity of the impact body respectively when the spherically test tip is located 1mm above the testing surface.
  • Page 13 (2)Too big roughness of the being measured surface could cause measure error. So the surface of the sample to be measured must appear metallic luster, smoothing and polish, without oil stain. (3)Support of test sample. Support is no necessary for heavy sample. Medium weight parts must be set on the smoothing and stable plane.
  • Page 14 though its weight and thickness is big enough, and accordingly, the test value may not be accurate. So the sample should be reinforced or supported at its back. (8)Magnetism of the sample itself should be avoided. Table 3 3.1.2 System Setting See 4.5 for details.
  • Page 15 3.2.1 Start-Up (1)Insert the plug of the impact device into the socket of impact device on the tester. (2)Press key，now power is connected. The instrument is in testing condition. Table 4: 3.2.2 Loading Pushing the loading-tube downwards until contact is felt. Then allow it to slowly return to the starting position or using other method locking the impact body.
  • Page 16 The action direction should pass the axis of the impact device. (2)Each measure area of the sample usually need 5 times of testing operation. The result data dispersion should not more than mean value±15HL. (3)The distance between any two impact points or from the center of any impact point to the edge of testing sample should conform to the regulation of Table 5.

    6 Malfunction analysis and maintenance <1> When using standard Rockwell hardness block to testing, if all the error is bigger than 2HRC, it may be the invalidation of impacted ball top caused by abrasion. Changing the spherical test tip or impact object should be considered. <2>When the hardness tester appears some other abnormal phenomena, please do not dismantle or adjust any fixedly assembled parts.
