The example illustrated in the figure refers to broaching a square on a hub, using the REV BROACHING TOOL. As in the previous example, this case also involves a piece that can be defined as 'special'. Executing the square is extremely simple as it involves repeating the same operation to create one side of the square four times, turning the C axis by 90°. Using the REV BROACHING TOOL for this type of machining not only offers the advantage of not having to move the piece, but also that of achieving a perfectly centred square on the piece, making it possible to correct measurements without difficulty. On the contrary, using traditional machines such as slotters, this operation of executing a square is time consuming and difficult, and it is not possible to achieve perfect centring between square and lathed piece. For the execution of square or hexagonal holes, our company can provide specific programmes for any CNC machine currently on the market.
