High-speed milling with ceramic significantly reduced cycle time compared to the current carbide inserts. (Single pass process went from 40 min. down to 15min.) SX6 achieved 1.4 times more tool life.

Tooling costs are reduced by utilizing negative inserts, increasing the number of corners.

As for competitor’s milling cutter, we needed to change inserts to new ones due to the wear progress and lower clamping force of work material after machining 60 pcs.
This was caused by increasing sutting force.

NTK NEW Milling cutter “FU-HA MILL” achieved 2 times longer competitor’s.
Low cutting force avoided the problem occurred by competitor’s milling cutter.

*Please make use of the above tables, understanding that they are approximations only to use as a guide.

Tips for utilizing the above tables
  • The assumption is that gray cast iron is machined at a cutting speed of 800m/min 2600 SFM , with the cutter diameter shown as the width of cut (ae= 100% of the cutter diameter).
  • The required power becomes approximately half (50%) if the cutting width ae or depth of cut is halved. (The power is proportional to ae or ap.)
  • The required power is reduced to approximately 60% if the number of inserts is halved.
  • Machines that have an output of 22kw or greater are recommended.
