Studies to avoid breaking tool in manufacturing by broaching operation

pdf PDF


In the paper is presented a study on the conditions to be met by the clamping device for the processing of the internal surfaces on the broaching machines. It is especially emphasized that in most cases, devices with spherical support are used for clamping the parts on the machine tool. They provide good conditions for avoiding the breaking of the broaching tool and meeting the dimensional, quality and geometrical conditions required by the technical documentation of the parts. The paper specifies the maximum and minimum limits between the size of the spherical device for a good execution of the broaching operation.
