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 conventional lathe with a C axis. The tool has a quarter-circle geometry with six teeth. The first tooth carries a complete 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 continuously 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.
Economic efficiency is an important consideration when choosing tools for challenging metals.
Applying ceramic inserts is not a simple substitution of one cutting tool material for another. There are significant process considerations that shops should examine carefully in order to realize performance and tool life expectations from ceramic inserts. Here's a look at some of the ways they are used.
Cutting holes by interpolating a face milling cutter may be a better process choice for many rough and even finish boring operations. Software improvements and better cutter designs allow expanding use of the versatile face mill for hole making.
