Abstract
A grinding machine tool for reducing hotness of a casing, includes a casing and a drive assembly. The casing is divided into a head and a body; includes casing parts; includes an air inlet provided on the body and an air outlet provided on a side of the head; and forms a motor cover on the head, and the motor cover does not contact the casing parts to form an airflow passage in the casing. The drive assembly includes a circuit board, a motor placed into the motor cover, and an airflow generating member rotating synchronously with the motor. When the airflow generating member rotates, it generates a first heat dissipation airflow passing through the airflow passage and dissipating heat of the circuit board and the head, and a second heat dissipation airflow dissipating heat on a side of the motor facing the airflow generating member.
