PTI Turret Interface

Uniformity, performance, and flexibility are the outstanding features of the new PTI (polygonal turning interface) turret interface. As a uniform mechanical interface, it lays the foundations for equipping modern lathes with flexible, precise, high-performance tool holders and driven tools. The media supply (coolant, air) and the data and energy transfer round off the PTI interface.

  • Coolant and sealing air supply
  • Tool holders can be used for either left or right machining
  • Data and energy transfer
  • Small size
  • Manual quick change
  • Automatic clamping possible
  • Takes other interfaces into account
  • Designed for standardization
