G-one HolderPAT.P
A Solution to the problem of
multi-blade boring cutters
- One-shot machining for high precision & high efficiency made possible by its special designed structure.
- NO need of edge run out adjustment
→ 45% setting time reduction - Use of standard inserts
→ 20% cost reduction - A single cutting edge
→ improves machining accuracy

“Amazing Ideas / Facts!”
The G-one holder consists of roughing and finishing edges.
By using a single finishing edge and standard inserts for roughing, the setting time is largely reduced (no need of skilled workers to set up).
Hence high productivity, high-precision machining and reduced costs are achieved.

Background / Point for Development
Background
- One shot machining with multi edged tools (instead of conventional rough & finish)has been established for high accuracy aluminum machining, to reduce the cycle time.
- However, “multi edges” always required longer setting up time and the run out adjustment.
Point for Development
- The G-one Holder integrates multiple cutting edges into a single holder.
By articulating each edge's function, it successfully reduced the setting up time and minimizing the total tools cost.
