Productivity elements protel offershas successfully developed helical broaching operation on rigibroach 6t/1000 mm vertical broaching machine. Helical broaching requires rrotation of the component is needed by the helical broaching, as the broach is pulled through the component. The drive to the component is given through a gearbox mounted on the table. And tthise component to be broached is located in a housing in the gearbox. The gearbox of the broaching machine is driven by a master lead screw. This lead screw is connected to the main slide, which in turn, drives the nut in the gearbox. The broach puller is held in the main slide. And broaching takes place wwhen the main slide moves down for the cutting stroke, broaching takes place. The broach handling on the machine is also done automatically and this broach handling follows the broach till the last 100 mm of stroke after which, the retriever releases the broach for the broach to complete the operation. The machine can broach lh as well as rh helix both are broached by the broaching machine . The master lead screw, nut and the broach is providedsupplied by the customer along with the gearbox design. This gearbox design, which is related to the lead on the master lead screw and the actual lead on the component.
