Abstract

Disclosed are a dual-wheel abrader and dual-wheel polisher comprising a head housing (1), an end cap (5) arranged at the front of the head housing, and an electric motor fixed on the head housing, with the electric motor having a rotor gearwheel (6), the rotor gearwheel being connected to a forward driven wheel (2) and a reverse driven wheel (3), the forward driven wheel being connected and fixed to a main shaft (7), an end of the main shaft being connected with an inner wheel, the reverse driven wheel being connected and fixed to an inner drive sleeve (4), an end of the inner drive sleeve being connected with an outer wheel (9), an end face of the inner wheel and an end face of the outer wheel being on the same plane and being concentrically rotatable in opposite directions. The forward and reverse rotations of the inner wheel and the outer wheel in opposite directions at the same time of the dual-wheel abrader and dual-wheel polisher improve the abrading effects, and since the counter-acting force caused when an object is abraded is automatically counterbalanced by the inner wheel and the outer wheel, the service life of the dual-wheel abrader is extended while reducing the labour intensity of the operator.
