Abstract

PURPOSE: To greatly shorten the time of machining and raise the accuracy thereof, by revolving a tool in a hole while feeding the tool in the axial direction of the hole and by ejecting a cutting agent to a machining point to wash chips away.
CONSTITUTION: When a flexible shaft 25 is rotated by a motor, a turning force is transmitted to a spindle 8 through a coupling 19. An attachment 31 is rotated together with the spindle 8. As a result, whetstnes 6aW6c are spread by the centrifugal force and strongly thrusted onto the inside surface 4 of a turbine rotor to grind the inside surface. At the same time, a machining head 5 held by support bars 7 in the hole is moved by the motor in the axial direction of the hole to uniformly grind the inside surface 4 of the hole in the axial direction. Cutting oil is ejected to the whetstones through an oil passage 26 of the machining head 5 and an ejection port 27 to prevent heating due to the machining.
