Practical Production Experience with Surface Broaching 340114
ACTUAL production experiences with several types of surface-broaching machines are cited by Mr. Chapman, who states that the shape of the piece, the number and the location of the surfaces to be machined and the required hourly production all affect the selection of the most suitable type of equipment.
The parts chosen by Mr. Chapman for citation are: A steel yoke, a front-wheel control-arm, a steering knuckle, a steering-gear cross-shaft, a free-wheeling cam, a small malleable cast housing and another small part that presented an unusual problem.
In each case cited, Mr. Chapman considers the part under the headings: Material, description, condition, operation, limits and stock removed. Regarding the production equipment, the headings are: Machine, fixture, broach, operation, production, and broach cost.
