Toolholders for a 30-60-Degree Angle
Groove ‘N Turn toolholders are available in 3/4" and 1" square and are used for making undercuts and thread reliefs at a 30-degree/60-degree angle.
Far from being outdated by the latest machine tool technology, angle heads often prove an ideal complement by pushing done-in-one capabilities even further. Proper application, however, requires attention to their limitations as well as their benefits.
Horn USA has developed quick-change tooling systems to drastically reduce set-up and toolchange times for Swiss-type lathes, including those with through coolant.
The force that holds the toolholder in the machining center's spindle can weaken over time. If you haven't checked drawbar force in a while, this may be the weak link in your process.
