MACHINABILITY OF 1006 STEEL
Steel 1006 is a Low Carbon Steel material with 0.1% carbon content. Most Carbon steels have between 0.08% to 1% carbon content. The machinability is very sensitive to the amount of carbon since carbon directly influences the hardness of steel. The "Sweet Spot" that yields the highest rating is 0.2%-0.3%.
Since Steel 1006 has a low carbon content, it is very soft. Thus, it is almost impossible to break the chips, and a "build up edge" ( BUE) is easily formed on the cutting edge.and a "build-up edge" ( BUE) is easily formed on the cutting edge. Therefore, although Its machinability rating is 55%, it's a problematic material to machine. It is best to cut Steel 1006 with a sharp cutting edge to reduce the built-up edge.
You can find here a list of machinability Ratings for different Carbon Steels.
Summary:
For general turning of Steel 1006 at stable conditions,use a grade with a rigid substrate and CVD coating.
If you are running at a cutting speed lower than 490 SFM (150 m/min), using a grade with a hard substrate and PVD coating is better.
Hard substrate and PVD coating.
For general milling, use the grade with a semi-hard substrate and thin PVD coating.
For detailed carbide grades recommendations,check the table below.
Recommended cutting speed range for turning at stable conditions is 670 - 900 [SFM] / 205 - 275 [m/min].
Recommended cutting speed range for milling with stable clamping and short over hang is 410 - 560 [SFM] / 125 - 170 [m/min]
For detailed cutting speed recomendations, check the Below Table.
