Machining Cast Iron GTS-70-02

GTS-70-02 is a Malleable cast iron material with a Machinability rating of 62% and Hardness 265 HB.

Malleable cast iron is a much tougher (ductile) material, with lower sensitivity to cracking and better impact resistance (compared to grey and nodular cast iron). As a result, it is harder to break the chips (compared to other types of cast iron) and can also be machined with geometry that is suitable for alloy steels

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.

Summery:

For general Turning of Cast Iron GTS-70-02 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 Below Chart, or use the Grades Wizrad.

Recommended Cutting speed range for turning at stable conditions is 390 - 540 [SFM] / 120 - 165 [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). Learn More ⇒

Recommended Cutting speed range for milling with stable clamping and short overhang is 260 - 360 [SFM] / 80 - 110 [m/min]
