ABSTRACT:
Base seat of a pneumatic grinder, including an air way and a water way disposed in the base seat to respectively communicate with an air chamber and a water chamber formed in the base seat. Several water outlets and a predetermined number of air rooms are disposed on a bottom face of the base seat. The water outlets communicate with the water chamber, while the air rooms communicate with the air chamber. Multiple ball bodies are respectively rollably disposed in the air rooms, the bottom edge of the ball bodies protrude from the bottom face of the base seat. When high pressure air and water are conducted into the air way and water way, the air is conducted by the air way to flow into the air chamber and to blow to the ball bodies in the air rooms making the ball bodies rolling easily. The water flows through the water way into the water chamber and then flows through the water outlets out of the bottom face of the base seat to reduce frictional force against the bottom face of the base seat.
