Abstract

PURPOSE: To cut the part of pin of crankshaft precisely and easily by moving the turning internal cutter up and down vertically on shifting the work, both ends of which are fixed, horizontally in the direction perpendicular to the axis.
CONSTITUTION: When the part of pin of crankshaft of the engine, which is to be coupled with the cone rod, is cut, both ends of the work are fixed to respective chucks of the work heads 2 on putting the work in the internal cutter 13 of the tool rest 7, and the respective parts are set so that the center of internal cutter of internal cutter 13 coincides with the center of journal. Next, the working is started, the internal cutter 13 which is being turned by the motor 14 is ascended together with the tool support 9 which is raised by the up-down feed motor 11, the cutting edge 13b is made come in contact with the pin, and the quadrant of the pin is cut by driving the horizontal feed motor 3. Successively, respective motors are synchronously controlled with fixed relations among them to complete the desired working.
