DEVICE AND METHOD FOR PROCESSING CURVED TOOTH BEVEL GEAR USING GEAR CUTTING PROCESS OF CONTINUOUS TOOTH CURVE FORMING TYPE

摘要

PROBLEM TO BE SOLVED: To enhance the use life of a gear cutting tool and the working efficiency so as to reduce the processing cost while enhancing the roughness of a finished surface of a workpiece by carrying out removal of chips and cooling under such a cutting condition that a cutter and the workpiece bite with each other. ;SOLUTION: In a method of machining a curved tooth bevel gear with the use of an annular milling cutter and a gear cutting process of continuous tooth curve forming type, cutting oil is fed from an external oil pressure source to a gear cutting part of a gear cutting tool 7 through an oil passage 18 formed in a cutter body 6. The cutting oil is fed only to the gear cutting tool 7 located in the machining area, by means of a cutting oil passage shut-off mechanism composed of a plunger 19 and a disc cam 12.;COPYRIGHT: (C)1997,JPO
