Products Specifications
The calibration anvil is used for calibration for test hammers.
The anvils are made of quality steel and tool steel, the mating surface between anvil core and body is treated with fine grinding process, the anvil core surface hardness is HRC58-62.
After 5000-8000 times operation, the test surface should be smoothed again, but the anvil core hardness shall be still kept in HRC58-62, otherwise it can't be used again.
The anvil shall be kept in dry and dust-proof place, should avoid any collision on the test surface.
