Abstract
The utility model provides a grinding mill specially used for a stress corrosion test sample, which comprises a mounting plate. A step wheel type central large rotating wheel is arranged in the center of the mounting plate and is connected with a motor, and a plurality of identical grinding power heads are uniformly arranged on the mounting plate; and conical friction wheels of the grinding power heads are in frictional contact with an upper wheel of the central large rotating wheel to rotate, and at the same time, disk friction wheels of the grinding power heads are in frictional contact with a lower wheel of the central large rotating wheel to rotate. The grinding mill can grind one test sample separately or eight test samples simultaneously, and provides the rotation power for the test samples, so that not only the test samples conduct high-speed rotations around the axial lines thereof, but also grinding cloth added with grinding paste clamps the test samples and conducts reciprocating motions along the axial direction. The dimensional precision and the surface roughness of the ground test samples meet the processing requirements, and the surface roughness is below Ra0.05. The manual assembly and disassembly of the test samples do not affect the states of other working positions, and the work efficiency is high.
