DEVICE FOR TESTING ABRASIVE TOOL Russian patent published in 2007 - IPC G01N3/46 

FIELD: testing engineering.

SUBSTANCE: device comprises the base with the stand, pendulum pivotally connected with the stand, unit for measuring angle of pendulum deviation, unit for adjusting depth of scratch, and electromagnetic members for locking the pendulum connected with a power source. The unit for measuring the angle of deviation of the pendulum is made of a pickup for measuring angular movement and is mounted on the axle of the pendulum. The unit for adjusting of scratch depth is made of a loading table mounted on the base for permitting vertical movement and rotation around the vertical axis. The table is provided with a three-component dynamometer. The pickup of angular movements and three-component dynamometer are connected with a computer.

EFFECT: expanded functional capabilities.
