TOOLING AND WORKHOLDING Modern Machine Shop 119 Broaching Tool Eliminates Cleaning Process for Serrated Turned Parts Schwanog's broaching tool eliminates the cleaning process step when machining serrated turned parts, creating a single-operation approach using a conven- tional lathe with a C axis. The tool has a quarter-circle geometry with six teeth. The first tooth carries a com- plete finish depth profile, while the remaining five teeth are considered roughing teeth. Broaching of serration is a two-step process. With the first step, the spindle does not move and the broach feeds three times until the first tooth is completely established. With the second step, the spindle starts indexing and the five successive teeth are con- tinuously broached until the finished depth is reached. The faster production cycles enabled by this system are said to reduce setup times and part cycle times. | Schwanog LLC 888-870-1055 schwanog.com Cutter Prevents Chipping in Spot Drilling Big Kaiser has introduced two versions of the C-Centering Cutter, a multi-function cutter capa- ble of spot drilling, center- ing and chamfering. The specialized insert can start a hole from a solid piece. It can also perform spot drill- ing and 90-degree cham- fering at the same time. The coolant hole enables cooling of the cutting edge, which reaches high temperatures during spot drilling, and enables immediate chip evacuation to prevent chip- ping during spot drilling. | Big Kaiser 888-866-5776 bigkaiser.com
