摘要： The invention concerns a vertical broaching machine in which several work blanks, such as rings, can be simultaneously provided with grooves at one or more broaching positions to which the work blanks, for example rings, are fed into the machine on a feeding device such as a slide onto a transporting device which moves the work blank or blanks to a broaching position where the grooves are formed by means of tools that move downwardly from the top, and after forming of the grooves the blanks are turned by an angle of 120* and are transported either to another broaching position for forming additional grooves or to a discharge device for completely broached blanks.
