Abstract

PURPOSE:To enhance the durability of a cutter for cutting the blade slot of a rotor of a pneumatic motor and accurately form the blade slot at the rotor in a short period of time. CONSTITUTION:A rotor 3 is eccentrically and rotatably journaled within the cylindrical bore 2 of a pneumatic motor body 1. The proper number of drilled holes 4, 4' are formed in parallel with the axis thereof at a position to be formed with a blade slot to be provided at the rotor body 3, and a blade slot 5 is cut by a cutter from the surface of the rotor 3. In this case, the holes 4, 4' are formed slightly larger in diameter than the width of the slot 5 in such a manner that the holes 4, 4' cross the slot 5. Since the rest at both sides of the holes 4, 4' becomes the escaping passage of cutting chips, it reduces the cut amount of the cutter so as to increase the life of the cutter and to accurately cut the slot at the rotor 3.
