Dynamic 5-axis milling with GARANT PPC mills and PPC indexable inserts

Für kürzere Prozesszeiten und höchste Oberflächengüten beim Fräsen


Our extensive range includes a suitable PPC milling tool for all materials and applications.

The PPC milling process, using barrel milling cutters, represents a further development of ball nose slot drilling. PPC stands for Parabolic Performance Cutting. The main application are are finishing operations of complex free-form surfaces and complicated components in general machine tool building, tool and mould making. PPC tools are also used where very high surface quality is required – for instance for press tools, in order to minimise subsequent polishing operations.

New: PPC indexable inserts in straight and stub conical form as well as solid carbide barrel millling cutters for machining hardened steel (red ring).

Advantages of the PPC process

  • Shorter machining times due to the large stepover.
  • Lower set-up costs.
  • General purpose tool bodies and specific indexable inserts.
  • Higher surface qualities at shorter cycle times.
  • Outstanding process reliability.
  • Extreme wear resistance.
  • Increased productivity.

GARANT Parabolic Performance Cutting (PPC) - a new strategy for highest productivity

GARANT Parabolic Performance Cutting (PPC for short) is a revolutionary new  development for machining free-form surfaces. Since the PPC cutters have a ground arc segment, they are also called barrel milling cutters. The arc segment affects the engagement area on the workpiece, which leads to significant advantages compared to machining with normal ball nose slot drills. This video shows how these advantages can be proven mathematically, and shows the various tool profiles offered by the GARANT portfolio.
