The invention discloses a machining technology for bearing holes in the two ends of a product shaft hole. In the two ends of the product shaft hole, at least one end is provided with an axial protruding part, and the center line of the axial protruding part coincides with the center line of the product shaft hole. The axial protruding part stretches into a fixedly-arranged positioning sleeve to be positioned. A first machining tool is used for conducting bearing hole machining at the end, away from the positioning sleeve, of the product shaft hole. A second machining tool stretches into the product shaft hole to conduct bearing hole machining at the other end, close to the positioning sleeve, of the product shaft hole. By the adoption of the above scheme, the second machining tool stretches into the product shaft hole to conduct bearing hole machining at the other end of the product shaft hole, the positioning sleeve is used for positioning the positioning hole of the axial protruding part, and conditions are
