(1) Purpose
In order to improve machining efficiency using the machining center we have, we utilize a new tool "KC Polar End Mill" based on new processing technology.
(2) Points of introduction
- New three-bladed radius end mill based on low speed high feed processing technology
- Special 3D negative shape with 3 blades reduces vibrating and heat generation
- Adopting a pocket shape with high discharge of chips
⇒ high-efficiency processing is possible by roughing, medium finishing, and finishing processing.

Since it is possible to reduce vibration by machining at low speeds, we were able to reduce machining time by about 67% compared to conventional tools.
In addition, since the vibration and heat generation were suppressed, we were able to perform processing without tool wear.
