MACHINABILITY OF GG10 CAST IRON

GG10 is a Grey cast iron material with a machinability rating of 170% and hardness 175 HB.

Grey cast Iron is the most brittle cast iron sub-group. It is the easiest to machine and produces tiny chips even when using a flat insert without a chip breaker

In Cast Iron, the material standards also define the allowed hardness range, and hardness is the top-ranking factor affecting the machinability ratings. For example, nodular cast iron is known to be harder to machine compared with grey cast iron. However, if a grey cast iron alloy has a hardness of 300HB is will have lower machinability than nodular cast iron with 200HB.

Cast iron is very brittle and produces short chips. Therefore, there is no need for a sharp cutting edge, and a strong geometry with a large honing or K-land is the best choice.


SUMMARY:
  • For general turning of Cast Iron GG10 at stable conditions use a grade with a very hard substrate and CVD coating.
  • In case you are running at a cutting speed that is lower than 490 SFM (150 m/min), it is better to use a grade with a very hard substrate and PVD coating.
  • For general milling use a grade with a semi hard substrate and CVD coating.
  • For detailed carbide grades recommendations, check the table below.
  • Recommended Cutting speed range for turning at stable conditions is 1080 - 1480 [SFM] / 330 - 450 [m/min].
  • Consider using CBN inserts. Although they cost more than twice, they enable increasing the cutting speed by 2-4 times (relative to carbide).
  • Recommended Cutting speed range for milling with stable clamping and short overhangis 740 - 1000 [SFM] / 225 - 305 [m/min]
  • For detailed cutting speed recommendations, check the table below.
